QUICK START INSTRUCTIONS
To fully benefit from your mixer you need a clean audio set up of the main
unit and eventually the extender unit.
MAIN UNIT CONNECTIONS
Make sure you start to connect the main unit only to your Control Room
Monitors and no other equipment. It means that the CRM cinch connectors audio
pin connects to pin 2 of an active monitor and the ground connects to pin 1
and 3 of the XLR of your active Monitor speaker set. Or use a ready made Cinch
to XLR cable. The AIRENCE is not grounded so your monitor speakers may be
grounded but not yet switched on.
NOTE: In 2022 we have designed new 12 volt 5Amp power supplies for both the
main and extender unit. Do NOT combine a new unit with an earlier design, it
will damage the electronics.
Now connect the power supply to the mixer and connect the the mixer to a power
source. Turn the CRM potentiometer fully left and switch the active monitors
(or your power amp) on. Turn up the input volume of the speakers half way and
listen if the speakers are quiet. If not remove the input cable from the
speakers and listen again. if this quiet again, then connect the speakers
again and pull the Cinch connectors out of the AIRENCE mixer and listen again.
if the noise dissappears, then check your cables carefully. Now turn up the
volume of the CRM potentiometer slowly and listen if the noise is not
increasing too much. (a little noise is acceptable). Now connect an audio
source such as CD player to one of the inputs and adjust the gain with the CUE
activated so the ledbar will indicate sufficient level. Now activate the ON
switch and slowly move the fader up until a sounf is heard. If it is getting
to loud reduce the CRM level until the fader is fully up. Now reduce the CRM
speakers input gain controls in a way the mixer’s CRM can be increased up to
75% and the signal is pretty loud. The next step is to connect your PC to your
system with a USB cable that came with the mixer. If the noise in the CRM
increases try to unground your PC or your monitor speakers. In some cases
(dependent upon PC brand) a high frequency USB noise can de detected. We then
advice to use an USB isolator in between the AIRENCE mixer and the PC.
Installation of the play-out software is instructed in the manuals of the
play-out software.
EXTENDER UNIT CONNECTIONS
Installation of the Extender unit goes as written below. Disconnect both the
Main unit and the Extender unit fror the power supply. Now use the 15 pole
Sub-D cable that comes with the Extender unit and connect it to the main unit.
Make sure the screws are tightened secure. Connect the power supply of the
Extender unit to the mains and also of the main unit. Switch the CRMonitor off
and connect the main unit and Extender to the mains power and switch on the
CRM. Now listen of there is an increase in noise (a little is acceptable). If
there is asubstantial increase in noise the following grounding can help. as
an option use and extra spare Cinch cable and disconnect the signal conductor,
so only the ground wire is still connected. Now push the cinch connector on an
unused Cinch connector on the main unit and on the Extender unit. This should
reduce eventually present noise. You can also use 2 XLR cables with only pin 1
connected by a thick ground cable. If this helps we can add a ground terminal
to your mixer if needed.

AIRENCE-USB Manual Page 4
AIRENCE MAIN UNIT BACKPANEL
The Main’s section back panel shows all the in and output connectors to
interface with your other equipment. The first 1 to 4 MIC/LINE/USB modules on
the right have balanced XLR mic inputs with a mic insert for voice processing.
A start connector to activate red light signalling individually or this reed
relay can be used to close (or pulse) a start contact to activate equipment
connected to the line input. Two cinch connectors accept these line left/right
input signals. Telco 1/2 have 2 RJ-11 standardized telephone connectors, a
stereo line input, in case you do not need the internal Hybrid modules and a
START jack that can switch (default) an external Telephone signaling device.
Or you can re-jumper the function of the start jack connector to control
external equipment when the line input is selected.
The master section houses all the in and outputs of the controls on the front
panel that we go into detail in other chapters. Most of the functions are self
explanatory, such as master right and left XLR’s and all the other in and
outputs. Worth mentioning is the redundant extra power supply connector where
an optional redundant power supply can be connected and the SUB-D slave
connection to the extender unit. And of course the USB connector that carries
all the 4 stereo audio signals to and from the PC (for both Windows &
Macintosh computers) as well as the Play-out systems control info from the
programmable Control section plus the Clock and meter information. This USB
feature will allow to connect to the Internet via your computer for “Live”
streaming of audio to the Internet.
AIRENCE-EXTENDER BACKPANEL
The back panel of the Extender unit provides you with 6 balanced XLR’s for Mic
input signals, an insert for processors, start switch and two pairs of Cinch
connectors for the stereo left right line inputs. On the left you see the 5
pin XLR connector for the external switched (high efficiency) power supply and
the Sub-D connectors for linking to the main unit and to possible extra
Extenders units. A 1 meter cable is part of the delivery of the Extender unit.
There is no limit in connecting more than one Extender unit to the main unit.
The extra inputs in a second (or third) Extender unit are connected to the
Sub-D connector labelled “to third(next) Unit”. Every Extender unit needs his
own power supply which of course is part of the delivery.
AIRENCE-USB Manual Page 5
AIRENCE MAIN UNIT TRIPLE INPUT MODULES 1-4
The input modules switches & controls of the main AIRENCE mixer have the
following functions: Each of Modules 1 thru 4 has three selectable inputs. The
three types of inputs consist of a Microphone input a stereo line input and an
USB input. In the Mic switch position, the module is a normal mono module.
When the Mic is switched out(up position), you have the choice out of a stereo
Line level inputs or USB stereo inputs to feed the stereo AUX send ,PROGRAM
and or SUB stereo mix busses.
GAIN
With the gain control (the first control knob below the modules number), the
source input level can be adjusted to the required internal mixer level. This
control adjusts both the Mic input and the stereo Line/USB inputs with the
same control depending on the switch positions. Mic gain can be more precisely
controlled with the small trimmer positioned just above the High EQ control. A
small flat screwdriver is needed. Try it in this way, if you cannot achieve
enough Mic gain when the gain control is fully turned clockwise, only then you
slowly turn to the right to increase the gain to the desired level. Also a mic
only low cut filter is built in, but this can only be reached/set when the
bottom of the console is removed. There are more jumper settings in the
console, so we advice to make a (jumper)plan for your situation and then do
all the internal jumper settings in one go. Or tell us through your dealer how
you want the jumpers selected and we deliver the console as requested.
STEREO LINE/USB
The stereo line input is a high impedance input ( >10 kOhm) for connecting the
stereo line level outputs of devices such as CD players/MP3 players etc. The
USB stereo signal comes directly from one of the 4 stereo USB channels from
your PC play-out software. These are already assigned in the Mixer by D&R. PC
play-out Channel nr 1 can be listen to in module 1 and this is also the case
for channel 2, 3 and 4. To match the incoming levels to a convenient control
range, internal trimmers are available labelled VR2 (right) and VR3 (left).
This also can only be done with the frame dismantled and should be done at the
same time that you do the jumper selections. Also the source selector for the
NON-STOP switching is on the module as a jumper. The main output XLR’s on the
mixer can directly receive a stereo signal from Program pre/Program Post/Sub
or Aux. A Picture will be shown in the manual how to achieve all these
settings the way you want it. If a USB signal is present the led on the right
side of the Line/USB switch will be lit.
MIC
The Mic input has a balanced XLR input connector with 48 volt phantom powering
for condenser mikes. The Mic-pre circuitry uses the latest technology studio-
class components as used in high end recording consoles, we use the That 1510
Mic-pre which is highly acclaimed for its low noise/distortion and transparent
audio. The low-noise design and excellent phase spec that D&R is known for is
integrated throughout the AIRENCE-USB which results in a phase coherent signal
path. Using balanced microphones & cables allows for the quietest and high
quality audio signals throughout your AIRENCE-USB mixer. You can use standard
balanced Mic cables available at any pro audio dealer or music store. The
AIRENCE-USB uses chassis-mount female XLR type Mic input connectors. Any
standard pro audio Mic cable will fit into this female XLR connector.
EQUALIZER
Each module has a stereo three band equalizer to control the high, mid, and
low frequencies individually. The D&R designers used carefully chosen
frequencies in the equalizer circuitry to enhance the Mic input as well as the
stereo A & B line inputs.
SUB
This switch routes the post Fader signal directly to the SUB buss, this SUB
buss can be used to make a sub mix for recording or any other creative
process.
PROG(RAM)
This switch routes the post Fader signal directly to the PROGRAM buss.
AUX SEND
The next control is a stereo Aux send that sends stereo source signals to the
stereo Aux send buss Master (or SUB buss) and then to the output connectors on
the Master back panel. The stereo Aux send is for external effects such as
reverb, echo or headphone amplifiers. Each Aux send can be set pre or post
fader by changing jumper settings on the circuit board of each module. The
factory default is post fader.
AIRENCE-USB Manual Page 6
CUE/COMMUNICATION BUSS
Below the AUX SEND is the stereo CUE switch (Pre Fade Listening), this switch
allows you to check the signal before you raise your channel fader up and mix
it with other signals in the mixer. Another smart function is that this CUE
bus can be used for communication. If you push a DJ’s Cue (let’s say channel
one) and if you then push the Telco Cue, the DJ as well as the caller can hear
each other outside the broadcast and even you, sitting behind the desk on the
monitor speakers. Note: Levels need to be carefully set to avoid feedback and
overdrive of circuits. The Cue switch also sends out HID signal over USB that
can be programmed to do specific functions in your play-out system. In the
Control section of the manual we will explain how.
ON
The ON switch is used to pass on the audio and at the same time generates a
start signal for turntables, CD players, and jingle or cart machines. This
switch sends out a momentary pulse or shortens continuously two pins of the
Start connector on the back panel of the console. A jumper setting on the PCB
let’s you choose between pulse and continuously. The ON switch also sends out
HID signal over USB that can be programmed to do specific functions in your
play-out system. In the Control section of the manual we will explain how.
FADER
Final audio level control is the high quality, 100 mm long throw K-Alps stereo
channel fader with integrated fader start switch. At the beginning of the
fader movement you will feel an integrated start switch that closes when you
bring up the fader. This switch activates the start circuitry that is
connected to the Start Connector on the module back panel as described
earlier. If the Mute-Act(ive) switch in the master section is activated,
positioned close to the CRM volume knob (and there is also one close to the
Studio volume knob), the control room level (or Studio level) will be dimmed
by 20dB when in the input module Mic is selected. At the same time a USB HID
(Human Interface Device) signal is sent to the USB bus for controlling a
function in your play-out software. On the pcb there is a jumper setting where
you can select if you want and extra 10dB of fader gain. Then the unity gain
position will be at the -10dB position. If you are a person that sweeps the
fader fully up and down, then do not select the extra fader gain of 10dB and
choose for a unity gain position in the fully up position of the fader. A
jumper setting page will be shown further in this manual to customize the
AIRENCE to your needs.
AIRENCE-USB Manual Page 7
AIRENCE MAIN UNIT TRIPLE INPUT USB MODULES 1-4
INPUT CONNECTORS
On the back of modules 1 thru 4, you find five connectors for each module. The
stereo line input uses Cinch female type connectors. Being un-balanced, the
shield and (-) or out of phase signal wire need to be connected together and
seen as ground during installation. In order to use the START switch, it
requires two pins in the ¼” stereo connector located on the back panel to be
wired. The tip and ring are shorted when the ON switch plus fader switch is
activated. Once you have done this, a quick start turntable can be started via
a shorted contact action in the ¼” stereo connector with the ON switch or with
the Fader, whatever your preference is, but only if the START connector is
wired on the back panel. If your turntable only needs a pulse to start, ask
your dealer. Or if you know how to temporarily remove the cover frame of the
AIRENCE you can change a jumper setting to a momentary action, so it can be
used as a pulse start switch. Connections on the START connector can only be
used for a maximum of 24 Volts at 50 mA. Please contact your dealer if you are
uncertain.
NEVER CONNECT AC POWER VOLTAGE TO THIS REMOTE-JACK
Or you can activate a function in your play-out software by USB HID
instructions that will be explained later in the USB CONTROL section of the
manual.
INSERT
This ring/tip/sleeve stereo jack socket let’s you insert signal processors
such as compressors/gates or special voice processing units to improve your
voice to sound like the ultimate announcer/D.J. The Ring of the stereo jack
sends the PRE-FADER channel signal and the Tip accepts the return signal. On
the right you see the type of cable you need when your processor has jack in
and outputs. Connect the tip from the stereo cable to the tip of one of the
mono jacks and the ring of the stereo cable to the tip of the other mono jack.
Now insert the stereo jack into the AIRENCE’s insert and connect the mono jack
that produces a hum when the tip is touched by your finger (and the related
channel fader is open) into the processors output. The other mono jack should
be inserted into the processors input.
In case your processor has XLR inputs connect the tip of the stereo jack to
pin 2 of the Female XLR and short pin 1 and 3 with each other and connect to
ground (sleeve), this also goes for the other Male XLR, connect the ring of
the stereo jack (which sends signals) to a male XLR pin2. Short here pin 1 and
3 and solder to ground (sleeve). This has to be done because the insert is not
balanced. See below the cable type you need.
MICROPHONE INPUT
The Mic input is a balanced female XLR type connector., see the left connector
below that should go into your mixer and your mic cable should end in a male
XLR as seen on the right section of the picture. 1=Ground/shield 2=Hot (in
phase) 3=Cold (out of Phase).
AIRENCE-USB Manual Page 8
SPECIAL OPTIONS FOR USB MODULES 1 – 4 (PCB AIRENCE-2)
Located on the input channel circuit boards are several jumpers that can be
changed to enable different configurations of the USB Triple input channel
settings. If changes are required, we advise you to contact your local dealer
to have these changes performed. But if you know something about electronics
and are not afraid to open up your mixer you can do it yourself. But… before
you do anything power must be removed from the console of course. The metal
cover frame must be removed to be able to reach the modules jumpers. This is
something you need to do only once before installation.
HOW TO REMOVE THE BOTTOM OF YOUR MIXER
First remove the 3 bolts below the faders that hold the cover, then put the
mixer upside down on a soft surface. You see on the back panel side of the
cover again 3 bolts that needs to be removed. Also on the left and right side
of the frame there are 2 bolts that needs to be removed. Once you have done
this you can lift the cover from the front and the back panel of the mixer.
Use a tweezer to lift and replace the jumpers. When the flat cables are in the
way, remove them by carefully lift the cables out of the headers. It is also
advisable to make up you mind how you want the AIRENCE to do his job for you.
Let me show you first a list of jumper settings and what you can achieve with
changing the jumper settings. I will also inform you about the factory default
setting and what is does. The jumper settings on the next page and trimmers
can be changed to adjust the AIRENCE to your needs.

SETTING UP THE USB MODULES
Above pictured you see a section of the USB pcb where you can decide which
output signal is sent to the USB connector. The default setting is PROG POST,
it means a post master stereo fader signal is sent to the USB connector and to
your PC. You can change this by moving both yellow jumpers two steps to the
left, now you have a PROG PRE master fader signal to the USB connector. There
are also options to get a signal from the Sub output or the AUX output. Be
aware that you always have to jumper for both the left and the right signal!
The level is set by the master faders of the mixer when PROG POST post
(default) is selected.
USB LEVEL TRIMMERS
On the top left of the picture above you also have two trimmers (VR2 and VR3)
that adjust the level that is sent to the USB chip in the AIRENCE and thus
adjust the outgoing level to your PC for left and right signal for the
selected jumper setting discussed earlier. This is especially important for
Windows 7 that recognizes the AIRENCE-USB chips we use as mic level signals. A
lower output level coming from the AIRENCE-USB will greatly improve
performance. We have no experience with WINDOWS-8 at the moment, but we will
update the manual as soon as we have done some tests. Also imbalances between
left and right could be corrected by these trimmers. An audio application
needs to run on your PC to be able to see the levels. Or else trial and error
is the only way. A free downloadable tool is to be found here
http://minorshill.co.uk/pc2/testgen.html To be able to adjust this level you
need to remove the bottom plate of the AIRENCE to access the trimmers, see the
description on page 8. The return signal coming from the PC USB is fixed but
can be adjusted with the AIRENCE modules Gain control.
A I R E N C E – U S B M a n u a l P a g e 12
SETTING UP THE USB MODULES
In order to set up a connection between your computer and the AIRENCE-USB mixer, use
a standard USB cable available from any local computer shop. (See picture). When con-
necting the AIRENCE-USB to your computer, the computer (PC or Mac) will recognize the
AIRENCE as new hardware and will establish a connection to any audio programs needing
audio hardware. After establishing a connection, there is no need to download drivers or
performing complicated setup routines, just plug in the USB cable to your Windows or Mac
computer and start tracking! (or playing a maximum of 4 stereo channels at the same time)

Telephone hybrids are hardware interfaces between professional audio equipment
and public telephone
networks. They provide protection for your equipment and the public telephone
lines, allowing for various line signals and line conditions. Automatically
canceling out the unwanted signal, they facilitate two-way communication when
using a single 2 wire telephone line. Each AIRENCE-USB hybrid module has a
Telephone line (WALL) connection and a handset connection. Thousands of D&R
Telephone Hybrids (also built into this AIRENCE-USB) are used in radio and
television broadcasting facilities around the World allowing external callers
to be connected to the studio mixer for live broadcast. Many of the D&R
Telephone Hybrids are supplied
to radio stations allowing extremely effective conversion between 4-wire audio
circuits and standard 2 wire telephone lines.
Specs:
Output Input R/C balance Separation
: Internally connected in the AIRENCE. : Line level 0 dBu balanced, internally connected in the AIRENCE. : fully adjustable. : more than 30dB.
TELCO SEND
With this control you adjust the level of the outgoing signal to the telephone
line.
PHONE / LINE INPUT SWITCH
When switched to the stereo line input, you have a high impedance line level
input for connecting cart machines, iPods, tape machines, or CD players. The
up position of this switch changes this module into a full blown telephone
Hybrid module. It is a Hybrid that can be connected to any standard telephone
line.
R-BALANCE
Internal potentiometer (screwdriver control) to adjust for maximum side tone
attenuation via top panel hole.
C-BALANCE
16 position rotary switch to select the optimum side tone (your own send
signal coming back from the telephone line) attenuation.
GAIN
With the GAIN control, the source level is adjusted to the internal mixer
level. This is for both the Telephone Line input and the Stereo Line inputs
(when selected)
CONNect
This switch (when pushed) picks up the phone line when a call comes in. Note:
the incoming call will not be heard until the CUE is pressed or the ON switch
and the fader are activated which brings the signal to the mixer. You can of
course have a handset with dial possibility to dial and pick up calls from the
caller first before you connect the caller to the mixer by pushing the CONNect
button. To hear the caller you have to push the CUE button and to bring the
caller on-air push the ON switch and pull up de fader.
TALKBACK
By pushing the TB switch on the Hybrid module, the internal talkback
microphone is activated and allows you to talk to the caller without being ON-
Air.
A I R E N C E – U S B M a n u a l P a g e 14
AUX SEND
Below the TB switch is the stereo Aux send that can be set to send stereo
source signals pre or post fader (pre or post jumper settings on the circuit
board). The factory default is post fader.
ROUTING
Each input module has SUB and PROG(ram) routing switches to route the stereo
signal to either the SUB bus, Program bus or both at the same time, or… not at
all.
CUE
Next you will see the stereo CUE switch (Pre Fader Listening). This switch
allows you to check the signal before you mix it with your other channel
signals in the mixer. A second very important function is that this Cue buss
is also designed to be a N-1 communication buss. It means that a caller hears
any signal connected to this Cue buss except his own signal. So communication
between a DJ channel and the caller is possible without having to mix in the
DJ channel and the caller in the broadcast.
RING (LED)
This LED lights to alert you when a call comes in,. You can also connect a
warning light to the START jack to be visually informed that a call comes in
(when you wear headphones).
ON
The ON switch is used to activate the module and generate a signal to start
turntables, CD players, cart or jingle machines. This switch sends out a
momentary pulse (default) or switches permanently (continuously) between tip
and ring of the Start connector on the back of the console. You can also use
this START connector to control an external Ring indicator that a call is
coming in. This is the default setting of the related jumper. You will notice
that the internal LED of the ON switch will not light when pushed as long as
the fader is not up alerting you that there is no signal sent to the busses
(Program or Sub).
FADER
Final control of the channel is the 100mm long throw K-Alps stereo channel
fader with integrated fader start switch. The channel fader sends the amount
of signal from the associated channel to the master mix buss. At the right
side of the fader you see a dB labelling starting at the top with no
attenuation (0) and sliding down it attenuates in steps of 5dB until it
reaches a full cut off below -90dB. When you are used to fully throw the fader
in its top position when opening a channel it is advisable to set the fader
gain jumper to 0dB (factory default). If you need a little bit of “playground”
for your audio, set the jumper to +10dB fader gain and see the -10dB (10)
position as your unity gain position. At the beginning of the fader movement
you will feel an internally built in start switch that is activated when you
bring up the fader. This switch activates the start circuitry and controls
externally connected devices such as CD players etc (via the Start connector
on the back).
INPUT CONNECTORS
On the back of each of the AIRENCE-TELCO modules 1 and 2 you find five
connectors. Two unbalanced stereo line RCA Cinch connectors for connecting CD
players, iPods, or any playback devices as long as they are line level
equipment. The level can be set using the gain control to match most source
levels. The left RCA/ Cinch connector is the right input and the right
RCA/Cinch connector is the left input. The shield needs to be connected to the
ground or case of the RCA/Cinch connector. The START switch has two active
connections to be wired. The tip and ring are shorted when the ON switch or
fader switch is activated. Default the tip and ring are shorted when a call is
coming in to alert someone is calling the studio. In case Fader start is
jumpered, you can start a turntable with the ON (if connected to the START
connector) switch on the back panel. These switches quick start turntables
through the remote jack by a continuous contact action between tip and ring at
the back of the mixer. If your turntable only needs a pulse to start ask your
dealer to modify the internal circuitry to change it into a momentary action,
so you can use it as a pulse start switch. NEVER CONNECT ELECTRICAL POWER TO
THIS REMOTE-JACK Connections on the START connector should only be made with
a maximum of 24 Volts by 50 mA. Please contact your dealer in case of doubt.
The two RJ11 connectors connect the
Module to the telephone utility companies phone line connection (Wall) and to
your telephone appliance (Phone) so you can dial-out to people you want to
interview or your radio program listeners.

SPECIAL AVAILABLE OPTIONS IN YOUR AIRENCE-TELCO MODULE
On the PCB of your TELCO AIRENCE module there are several jumpers and 2
trimmers that can be changed/trimmed to enable different configurations of the
channel settings. This should be done by a D&R dealer, service center or
yourselves if you are not afraid of electronics and screwdrivers. But… be sure
to remove the mains cable(s) first!!

VoIP-CHANNEL
In the AIRENCE USB we have built in an interface that let you connect to the Internet community by way of (for instance) Skype. Skype is freely available communication software that can be used to call and receive calls of your listeners to your broadcast station. We have designed a separate USB connector on the backpanel of your console to interface with SKYPE software. This could be on the same PC (on a second USB connector) as the Play-out system is installed or on a separate PC for dedicated use of the VoIP chan-nel with SKYPE software. For downloading the SKYPE software go to http://www.skype.com and then to your own language for more support. There are some SKYPE software settings you need to go through before this is working with your console. For some usefull instructions go to: https://support.skype.com/nl/faq/FA34541/een- perfect-skype-gesprek-voeren (Dutch instruction video, but I am sure there is one in your own language or in English of course).
GAIN
With the GAIN control, the source level is adjusted to the internal mixer level. This is for both the VoIP and the Stereo Line input (when selected)
VoIP(TELCO)-LINE SWITCH
When switched to the VoIP (Phone) position only the VoIP signal is received. When this switch is up, you have a high impedance stereo line level input for connecting an external Hybrid or… cart machines, iPods, tape machines, CD players etc.
VoIP (TELCO) SEND
With this level control the outgoing signal from the mixer is sent to the caller via Skype or and via an external connected Hybrid. This is for both the VoIP and the Stereo Line input (when selected). This Hybrid get’s it send sighnal from the cleanfeed output on the back of the console. .
CONNect
This switch (when pushed) picks up the VoIP/Hybrid signal when a call comes in. Note: the incoming call will not be heard until the CUE is pressed or the ON switch and the fader are activated which brings the signal to the mixer.

A I R E N C E – U S B M a n u a l P a g e 20
AIRENCE MASTER SECTION
The AIRENCE master section houses all the controls for the mix buss Program
faders and master controls for Aux return, EXT (2-Track) play-back, and master
outputs. Individual functions are described below in sections as shown on the
front panel below. Later version do NOT have the master faders anymore.
LEDBAR METERS
The master section has two high-res 11 segment LEDbar meters with VU meter
Ballistics. Depending on which switch is pressed (CUE on channels, AUX SEND
master, SUB, AUX RET, EXT, etc.), the master meters will allow the reading of
all input and outgoing signals. The attack and release time constants conform
to International VU meter standards, being 300mSec for attack and decay. The
green area of the LEDbar is the safe area and occasionally a red led on is no
problem. The output of your AIRENCE-USB is +6dBu (1.55v) (“0” VU) when the 0
green LED is on. Both led bars have trimmers for fine adjust and other
requested display levels.
PROGRAM MONO SWITCH
This switch turns the stereo signal into mono for both main outputs. Using
this switch is a convenient way to check and balance the left & right signals
before going to stereo as well as checking the overall Phase response. Also
when one side of the stereo signal is not available, the mono switch directs
the mono signal to both outputs.
EXTERN INPUT
The External(2 TRACK/OFF-AIR) switch allows for playback of the outputs from
stereo devices such as CD players, tape machines, computer sound cards, iPods,
or the OFF-AIR signal to be routed to the CRM (monitor buss). Its sensitivity
is -10dBv (300mV). Note: The Cue system (from anywhere in the mixer) will
interrupt the EXT signal when activated.
RECORD OUTPUT (Rec Out)
The AIRENCE has a Record output on Cinch connectors. These outputs can be fed
from SUB or from AUX or when both are in its up positions the main program
Signal is being send to these outputs.
AUX SEND
The stereo AUX SEND master controls the sum of the entire individual stereo
Aux send signals coming from the input channels. A Cue button let’s you hear
what is on the Aux send buss in stereo.
AUX CUE
The AUX SEND CUE switch allows for the master LED bar meters to display the
Aux output signal of the Aux master as well as listening to the signal from
the AUX buss. It is necessary to turn the AUX SEND master control up to be
able to create and show an outgoing AUX signal.
AUX RETURN
This stereo input is intended to be used for returning the stereo outputs of
reverbs or other effects gear and can be routed to the Program and SUB bus. It
can also be used to connect the output of other mixers so you don’t use input
channels.
CUE AUX RETURN
This switch enables you to listen to an incoming Aux return signal before the
AUX RET (Return) control pot.
SUB SEND
The stereo SUB SEND master controls the sum of the entire individual selected
Sub routing push buttons send signals coming from the input channels. A Cue
button let’s you hear what is on the Sub send buss
A I R E N C E – U S B M a n u a l P a g e 21
STUDIO
The AIRENCE has a separate Studio output that normally follows the Program
pre-fader left and right signals, but in case a guest wants to hear a caller
switching to Follow Phones enables him or her to listen tot the CUE system and
to communicate with the caller outside a broadcast. You can connect the inputs
of reverbs from these outputs (with Aux send jumpered to post fader) or use
them as a monitor output, after you jumper the Aux send in the channels to pre
fader.
FOLLOW PHONES
This switch is an input selector for the STUDIO output. Instead of listening
to the main outputs, it allows the user to listen to the phones output. This
feature is used by announcers and DJ’s that do not want to use headphones all
the time.
Mute by Mic
This latching switch (when pushed down) allows control signals (mic on) coming
from the DJ mic to mute the CRM speakers. This is to avoid signal feedback in
the studio area and keeps the DJ’s sound clear. At the same time a relay is
activated which is connected to the Red Light output connector on the back of
the master section. A jumper in the mic channel needs to be set to allow this
control signal to Mute the Control Room Monitors.
ANNOUNCER
The AIRENCE has a separate Announcer output that normally follows the Program
prefader left and right signals, but in case a guest wants to hear a caller
switching to Follow Phones enables him or her to listen tot the CUE system.
FOLLOW PHONES
This switch is an input selector for the announcer output. Instead of
listening to the main outputs, it allows the user to listen to the phones
output. This feature is used by announcers and DJ’s that do not want to use
headphones all the time. Also the CUE communication bus can be accessed to
communicate with anyone connected to it.
CRM SECTION (Control Room Monitor)
The CRM control is fed by the master outputs pre (before) the masterfaders.
This can be used as an extra stereo output for recording or a sound system in
which you do not want the master faders to change the out-going signal.
FOLLOW PHONES
This switch is an input selector for the CRM output. Instead of listening to
the main outputs, it allows the user to listen to the phones output. This
feature is used by announcers and DJ’s that do not want to use headphones.
BALANCE
The balance knob controls the balance between the main stereo Program output
and the stereo Cue signal when selected. With the balance control anywhere
between Cue and L/R you always have control over the main output signal even
when a Cue switch is activated. Note: The split switch de-activates the
balance control.
SPLIT
When the split function is activated the following listening situation is
created. The left side of the phones output gives the summed Cue signal and
the right output gives the summed left/right signal (pre fader). With the
SPLIT switch activated, the balance control has no influence on the
configuration any longer.
A I R E N C E – U S B M a n u a l P a g e 22
TALK BACK
The Talk back circuit has a built in electret microphone with routing to most
of the outputs. By selecting one or more of the routing switches, you can
communicate to the outputs SUB/AUX/STUDIO and Announcer. The Talk back level
is independent of settings of the master controls and Announcer outputs. An
exception is the AUX output, here the Talk back level is also dependant upon
the master level setting of the AUX master.The Talk back switch has a
momentary action to avoid being in the talk back mode when not wanted. As can
be seen in the Telco module there is a Talkback switch routing the built in
Electret mic directly to the caller. If an announcer who wants to talk to the
caller and is not sitting in front of the mixing consoles, he can use his
Presenters Mic, the engineer activates both the Announcers mic channel’s CUE
and the caller’s CUE and now both can talk with each other.
MASTER FADERS
The AIRENCE master faders are removed by many customer requests.
PHONES
The phones output (located on the front panel) automatically switches between
Main Program outputs and CUE from any input module or from the Master section.
Normally the left/right output is heard until a Cue switch is activated from
anywhere in the console. By pressing a CUE switch, you will hear the
associated signal rather than the left/right signal in the PHONES. The led bar
switches accordingly with this action. We advise you to use headphones with an
input impedance NO LOWER THAN 400 Ohms to avoid mismatch or distortion. An
8-32 Ohm set of headphones will produce distortion when cranking up the level
of the AIRENCE to high due to the fact that the impedance load is too low. If
you must use 8-32 ohm phones, a small power amp should be used to power the
phones. It is a load equivalent to the load that loudspeakers normally present
to power amps. The AIRENCE has no power-amp built in, sorry.
NONSTOP (on the left side of the control module)
The Non Stop switch is a very convenient function when you want to use your
mixer while NON STOP on-air. By activating this switch a by you pre selected
USB channel (1,2,3 or 4) sends its signal directly to the main XLR outputs,
making your mixer completely free for production. A CUE switch let’s you
listen to what you’re broadcasting directly out of your Play-out system. Two
Trimmers are available to even out any level differences between NON stop mode
and On-Air mode,
METERING
Part of the total AIRENCE package is a software meter application and clock as
seen below. All data are transported over the single USB 2.0 connection. An
accurate NTP clock time is taken from the Internet. Be sure to have access to
the Internet. The big left meter always shows the Program output, the other
big meter shows the SUB output level and the smaller meter on the right hand
side follows every signal selected by the CRM section.
A I R E N C E – U S B M a n u a l P a g e 23
MASTER BACKPANEL CONNECTORS
The master connector panel houses 18 RCA/Cinch connectors, 2 jack sockets, and
2 male XLR connectors. There are two power supply connectors, USB connector
and the SUB-D type connector to connect a slave unit to the main unit. From
right to left we will describe the functions and features of the master
connector panel.
AUX SEND
The aux outputs are on two RCA Cinch connectors with the signal coming from
the aux send controls in the channels. The level is +6 dBu (1.55 volt). You
can connect the inputs of reverbs from these outputs (with Aux send jumpered
to post fader) or use them as a monitor output, after you jumper the Aux send
in the channels to pre fader.
CRM SEND
The CRM (Control Room Monitor) outputs are on two RCA Cinch connectors
carrying the signal coming from the CRM volume potentiometer on the front
panel and its associated source selection. The level is +6 dBu (1.55 volt).
You can connect the inputs of Active monitors to Cinch connectors.
PROGRAM SEND
The PROG (Program) outputs are on two RCA Cinch connectors carrying the same
signal as is on the Master left right XLR’s and stays there also when the NON
STOP ON-AIR switch is activated. Then the main XLR outputs carry the USB
signal from one of the USB inputs. This non switched output can be used for
recording when the console is in its NON STOP mode. The Prog output connectors
are left and right outputs for connecting the inputs of a stereo audio
recorder or any other analog or digital device. Output level is -10dBv
(-7.8dBu / 300mV), the signal is post master fader.
AUX RETURN
The Aux return connectors are controlled by the Aux return control on the
master section. The signal is connected directly to the master main mix
busses. You can connect reverb returns or other stereo signals without using
any input modules. The input level should be at least -10dBV.
EXT(ERNAL) INPUTS
These inputs are for instance intended to return stereo ON-AIR signal in the
monitor section for checking live On-AIR signals. The input level should be at
least -10dBV.
CUE SEND
The CUE outputs are on two RCA Cinch connectors with the signal coming from
the CUE mix busses to be send to a separate CUE loudspeaker. The level is +0
dBu (0.775 volt).
STUDIO LEFT RIGHT
The studio outputs are on two RCA Cinch connectors carrying the signal coming
from the studio volume potentiometer on the front panel and its associated
source selection. The level is +6 dBu (1.55 volt). You can connect the inputs
of Active monitors to these Cinch connectors.
RECORD OUT
The Record Out cinch connectors normally send out the Program-Pre master fader
signals, unless its source selection is switched to from SUB or from AUX.
Output level is -10dBV (-7.8dBu / 300mV)
SUB OUTPUTS
The SUB outputs are on two RCA Cinch connectors carrying the signal coming
from the SUB summing amps. This non switched output can be used for recording
when the console is in its NON STOP mode, or for sending out channel selected
signals. The level is dependant upon the SUB master volume control and can be
listen to post SUB master by way of the CUE push button.
A I R E N C E – U S B M a n u a l P a g e 24
ANNOUNCER OUTPUT
The Announcer output is on a Stereo jack connector and carries the signal
coming from the Program Announcer amps. This output can be used for sending
signal to the announcer in the Studio. Normally this output carries the main
program signal unless the follow phones push button is activated, then the
announcer can be linked to Cue signals for communication with DJ’s and or
Callers. The level is dependant upon the Announcer master volume control and
is able to drive 400 Ohm headphones as a minimum impredance. If more
headphones need to be connect a separate headphone amp is a solution.
MIC ON
Directly beneath the SUB cinch connectors is a stereo jack socket (Mic On)
that can control a red light indicator. This stereo jack is connected to a
change over relay. This relay is capable of controlling external Red light
circuits as long as it doesn’t take a higher voltage than 24 volt and the
current doesn’t exceed 50 mA! Individual channels can be OFF jumpered from
this buss.
NEVER CONNECT 115/230 AC VOLTAGE TO THIS JACK!!
The C.C. (Center Contact) of the internal relay is connected to the Tip of the
stereo jack. The N.O. (Normally Open) contact is connected to the ring of the
jack. The N.C. (Normally Closed) contact is connected to the “sleeve or
ground” of the jack.

external power adapter.
A I R E N C E – U S B M a n u a l P a g e 25
MASTER OUTPUTS
The master outputs are 3 pin male XLR connectors and are electronically
balanced and can be connected to an input of a power amp, professional
recorder or On-Air processor. The output level is +6 dBu (1.55 volt).
POWER CONNECTOR
These two 5 pin XLR connectors accept external 36 volt 5A switched low energy
power supplies that are part of the delivery. DO NOT USE ANY OTHER POWER
SUPPLY THEN THIS ONE!!! Your AIRENCE can accept voltages between 90 AND 230
volts at 50/60Hz. The main unit of the AIRENCE works perfectly on one external
power supply unit, but incase redundancy is requested, a second unit can be
connected to the second power XLR connector. If one fails the other takes
over.
SUB-D CONNECTOR TO SLAVE UNITS
The AIRENCE has a Sub-D connector where you can connect an input slave unit
with 6 triple inputs to extend the number of inputs of your system. All (ON-
AIR) and CUE control signals are sent also through this low impedance module
link. And… there is no limit to the number of extender units that can be
connected, see it this way. The first extender unit plugs into the main unit
and the second Extender unit plugs into the first Extender unit and so on if
more input channels are needed.
OPTIONAL AES/EBU OUTPUT
It is possible to order an optional digital AES output. In some versions of
the AIRENCE-USB we use the second redundant Power supply connector for that
purpose. In other versions there is a third 3 pole XLR left of the Redundant 5
pole connector. Default the AES is set to the following values. HEADROOM:
-20dBFS (with jumper) No jumper means -9dBFS Sample Rate: 48kHz (with jumper)
No jumper means 96kHz

SET-UP ROUTINES MODULE 1-4
· Connect a power-amp, recorder, or transmitter to the Master left/right main
outputs. · Connect a high impedance (NOT BELOW 400 Ohm) headphone to the
“phones” jack socket on the master section. · Connect a microphone or line
level equipment. · Now, connect turntables, CD players, and jingle machines. ·
Connect a red light indicator to the master section when there is a need for
it. · The Studio and Announcer outputs can feed high impedance (400 ohms and
above) stereo headphones directly. · · Now with everything connected, follow
the adjustment procedure. · Note; for mikes, only activate the grey Mic
switch, for line level, leave this switch up and select line in the up
position of the
upper switch in the module. · Put on your headphones and turn the headphone
volume control to the “12 o’clock” position. · Set all the gain-controls and
the master faders to its minimum. · Set all equalizer-controls to the “12
o’clock” position. · All push button-switches should be in the up position,
except for the Prog routing switches in the modules. · Connect your external
power supply and connect this supply to the mains voltage, the first LED in
the LEDbars should be on.
SETTING UP AN INPUT CHANNEL
Push the CUE switch in a channel that is connected to a source. Now slowly
turn the GAIN control clockwise until you hear and see the input signal on the
LED bars in the master section. You can change the input sound by adjusting
the equalizer-section. If you adjust the equalization, once again check the
level on the led bar, because increasing specific parts of the frequency
spectrum can easily add more gain to the signal. If you can’t get enough gain
(when you have a low sensitivity dynamic microphone) the trimmer on the 2
o’clock position above the GAIN control knob could be trimmed for more or less
gain. The LEDbar indication should be between -6 dB and +6 dB to get a proper
level on amplifiers or recording devices. The LEDbar is a VU meter indicating
the absolute level that enters the console. It is calibrated to indicate 0 dB
on the scale corresponding with a +6 dBu output level. Release the CUE switch
so the led bar can now read the output signal again. Now push the ON button to
connect the input signal to the fader. Now move the fader to the “10” position
screened alongside the channel faders and turn up the master fader to the “0”
position. Further volume adjustments can be made on the equipment your signal
is send to, such as power-amps or transmitters. The other inputs are similarly
adjusted, using the “CUE” switches to (pre fade) listen to the connected
sources. Use the input gain for regular gain adjustment and the trimmer for
fine adjustments to create a convenient gain range to work with.
Be carefully not to place the AIRENCE near heavy power transformers such as
power amps. Although the AIRENCE is constructed using a thick metal frame,
this could cause hum.
SETTING UP THE USB MODULES
Input modules 1 to 4 are also capable of accepting stereo USB signals from a
PC where you have play-out software running. To be able to set up a connection
with your PC, use a standard USB cable from a local computer shop. (See
picture). When connecting the AIRENCE to your computer, the computer (PC or
Mac) will recognize the AIRENCE as new hardware and will establish a
connection to any audio programs needing audio hardware. Also all 4 stereo
channels will be automatically put in a natural sequence of 1 to 4. After
establishing a connection, there is no need to download drivers or performing
complicated setup routines, just plug in the USB cable to your Windows or Mac
computer and start tracking/ playing! If you first want to know more about USB
try this link http://en.wikipedia.org/wiki/Audio_Stream_Input/Output If you
are already familiar with digital audio recording, the latest versions of
Kristal Audio Engine and Audacity are available free of charge via the
Internet. Use this link http://www.asio4all.com/ for third party downloads.
A I R E N C E – U S B M a n u a l P a g e 27
SETTING UP THE TELCO MODULES
Connect the two wires of the telephone line’s wall connector to the RJ-11
connector labelled wall (LINE) and connect the telephone unit (the one
that has a dialer and handset) to the RJ-11 connector labelled PHONE. Note
that to originate calls, a local phone must be connected to the AIRENCE, so
you are able to dial a number. Once the dialed person has taken the call you
can talk to him via the handset and inform him that he will be in the
broadcast soon. You do this by pushing the connect button in the TELCO module.
if you now want to hear him or her again in the mixer push the CUE button in
the same channel you have pushed the Connect button and listen to the Cue
signal through the CRM (follow phones active) or via your headphone output. If
you want some else to talk to him or her also prior to the broadcast push any
CUE button and communication is established.
Now the internal hybrid is interfaced (fully balanced) between your telephone
appliance and its connection to the outside world. The hybrid can now split
the send and return signals.
Position both Telco send and gain potentiometers in the 12 o’clock positions.
If a local phone is connected, originate a call to a remote site (someone’s
phone). If no local phone is present, someone at a remote site must call you.
When a call comes in, the red RING LED (positioned between the CUE and ON
switches) lights up each time the phone rings. The line is picked up by
pushing the CONN button.
If you want to hear the caller, press in the same channel the CUE button to
listen to the incoming call. Adjust the Gain control to get a good input level
from the telephone line. To be able to talk to the caller press the TB
(Talkback) button and… talk to him or use another MIC input of the mixer and
push the CUE there too. Adjust the Telco send potentiometer to increase or
decrease the outgoing level to the caller. Note: This is all happening outside
the broadcast. If all is OK and both parties know what to do, you can press
the ON switch and fade up the caller ON-AIR, or, put the fader in its “0 or
10” position and activate the ON switch to put the caller on-air. Before going
“live” with your caller, you will need to adjust the optimum RC balance to
create the best separation of in and outgoing signals to the telephone line,
otherwise your listeners will be presented with bad quality audio and your own
voice will be influenced by crosstalk of your own signal feeding en returning
from the Hybrid. These adjustments are only required once when installing the
AIRENCE. To achieve the optimum attenuation, you must adjust the C and R
balance first.
This is how it is performed:
1. Check if the Telephone connection is established and all connections to
the mixing console are correctly wired.
2. Send an audio signal to the telephone line by activating another module,
for example, a CD player. 3. Now activate the CUE button of the TELCO module
where the telephone line is connected. 4. You will faintly hear the send
signal coming out of the mixing console. 5. Adjust the R-Balance for minimum
feed through of the mixers send signal. 6. Listen now which switch position of
the C-balance gives a further reduction of the return signal. 7. Maybe it is
good to re-adjust the R-balance after having selected another switch position.
8. Repeat steps 5 and 6 until no further improvement is achieved for this
telephone line. 9. Note: If you use the mixer in different locations this
procedure must be done again.

EXTENDER TRIPLE INPUT MODULES 1-6
The input modules switches & controls of the main AIRENCE-EXTENDER mixer have
the following functions: Each of Modules 1 thru 6 has three selectable inputs.
The three types of inputs consist of a Mic input a stereo line input and a
second Stereo LIne input. In the Mic switch position, the module is a normal
mono module. When the Mic is switched out, you have the choice of Line A or
Line B stereo inputs which allows for the module to become a stereo module
with both left & right signals to feed the PROGRAM and or SUB stereo mix
busses.
GAIN
With the gain control (the first control knob below the modules number), the
source input level can be adjusted to the required internal mixer level. This
control adjusts both the Mic input and the stereo Line/Line inputs with the
same control depending on the switch positions. Mic gain can be more precisely
controlled with the small trimmer positioned just above the High EQ control. A
small flat screwdriver is needed. Try it in this way, if you cannot achieve
enough Mic gain when the gain control is fully turned clockwise, only then you
slowly turn to the right to increase the gain to the desired level. Also a mic
only low cut filter is built in but this can only be reached/set when the
bottom of the console is removed. There are more jumper settings in the
console, so we advice to make a (jumper)plan for your situation and then do
all the internal jumper settings in one go.
STEREO LINE/LINE
The stereo line input is a high impedance input ( >10 kOhm) for connecting the
stereo line level outputs of devices such as CD players/MP3 players etc. The
second Line B input can accept a D&R stereo Phono Pre-amp with a RIAA
equalizer curve to accept turntable pick ups. This RIAA correction amp can be
purchased in our D&R webshop.
MIC
The Mic input has a balanced XLR input connector with 48 volt phantom powering
for condenser mikes. The Mic-pre circuitry uses the latest technology studio-
class components as used in high end recording consoles, we use the That 1510
Mic-pre which is highly acclaimed for its low noise/distortion and transparent
audio. The low-noise design and excellent phase spec that D&R is known for is
integrated throughout the AIRENCEUSB which results in phase coherent signal
path. Using balanced microphones & cables allows for the quietest and high
quality audio signals throughout your AIRENCE-USB mixer. You can use standard
balanced Mic cables available at any pro audio dealer or music store. The
AIRENCE-USB uses chassis-mount female XLR type Mic input connectors. Any
standard pro audio Mic cable will have the mating male XLR connector.
EQUALIZER Each module has a stereo three band equalizer to control the high,
mid, and low frequencies individually. The D&R designers used carefully chosen
frequencies in the equalizer circuitry to enhance the Mic input as well as the
stereo A & B line inputs.
SUB
This switch routes the post Fader signal directly to the SUB buss, this SUB
buss can be used to make a sub mix for recording or any other creative proces.
PROG(RAM)
This switch routes the post Fader signal directly to the PROGRAM buss. This
PROGRAM signal is directly routed to the main outputs of ther mixer via the
master faders.
AUX SEND
The next control is a stereo Aux send that sends stereo source signals to the
stereo Aux send buss Master (or SUB buss) and then to the output connectors on
the Master back panel. The stereo Aux send is for external effects such as
reverb, echo or headphone amplifiers.
CUE
Below the AUX SEND is the stereo CUE switch (Pre Fade Listening), this switch
allows you to check the signal before you raise your channel fader up and mix
it with other signals in the mixer. Another smart function is that this CUE
bus can be used for communication. If you push a DJ’s Cue (let’s say channel
one) and if you then push the Telco Cue, the DJ as well as the caller can hear
each other outside the broadcast and you sitting behind the desk as well.
Levels need to be carefully set to avoid feedback and overdrive of circuits.
A I R E N C E – U S B M a n u a l P a g e 30
ON
The ON switch is used to activate the module and generate a start signal for
turntables, CD players, and jingle or cart machines. This switch sends out a
momentary pulse or shortens continuously two pins of the Start connector on
the back panel of the console. A jumper setting on ther PCB let’s you choose
between pulse and continuously.
FADER
Final control is the high quality, 100 mm long throw K-Alps stereo channel
fader with integrated fader start switch. At the beginning of the fader
movement you will feel an integrated start switch that is activated when you
bring up the fader. This switch activates the start circuitry that is
connected to the Start Connector on the module back panel as described
earlier. If the Mute-Act(ive) switch in the master section is activated,
positioned close to the CRM volume knob and there is also one close to the
Studio volume knob, the control room level (or Studio level) will be dimmed by
20dB in case in the input module Mic is selected. At the same time a USB HID
(Human Interface Device) signal is sent to the USB bus for controlling a
function in your playout software. On the pcb there is a jumper setting where
you can select if you want and extra 10dB of fader gain. Then the unity gain
position will be at the -10dB position. If you are a person that sweeps the
fader fully up and down, then do not select the extra fader gain of 10dB and
choose for a unity gain position in the fully open position of the fader. A
jumper setting page will be shown further in this manual to customize your
AIRENCE to your needs.
INPUT CONNECTORS 1-6
On the back of your AIRENCE-EXTENDER modules 1 to 6 you will find the
following seven connectors. Two unbalanced line A input RCA Cinch connectors
(stereo input) for connecting CD players or any play-back devices such as cart
machines, cassette players, or iPods. Any line level equipment can be
connected here. The level can be set using the gain control to match most
source levels.
The left RCA Cinch connector is the left input and the right RCA Cinch
connector is the right input. The shield is to be connected to the ground or
case of the RCA Cinch connector. The Two unbalanced line B input RCA Cinch
connectors (stereo inputs) are a second stereo input in this
module to connect even more line level equipment to. The START switch has two
active connections to be wired. The tip and ring are shorted when the ON
switch or fader switch is activated. Once you have done this, you can start a
turntable or other devise with the ON switch via the START connector on the
back panel. The START switches quick start turntables through the remote jack
by a continuous contact action at the back of the mixer. If your turntable
only needs a pulse to start, ask your dealer to modify the internal circuitry
to change it to a momentary action, so it can be used as a pulse start switch.
NEVER CONNECT THE MAINS TO THIS REMOTE-JACK
Connections on the START connector can only be made with a maximum of 24 Volts
by 50 mA. Please contact your dealer in case of doubt.
A I R E N C E – U S B M a n u a l P a g e 31
INSERT
This ring/tip/sleeve stereo jack socket let’s you insert signal processors
such as compressors/gates or special voice processing units to improve your
voice to sound like the ultimate announcer/D.J. The Ring of the stereo jack
sends the channel signal and the Tip accepts the return signal. On the right
you see the type of cable you need when your processor has jack in and
outputs. Connect the tip from the stereo cable to the tip of one of the mono
jacks and the ring of the stereo cable to the tip of the other mono jack. Now
insert the stereo jack into the AIRENCE’s insert and connect the mono jack
that produces a hum when the tip is touched by your finger (and the related
channel fader is open) into the processors output. The other mono jack should
be inserted into the processors input. In case your processor has XLR inputs
connect the tip of the stereo jack to pin 2 of the Female XLR and short pin 1
and 3 with each other and connect to ground (sleeve), this also goes for the
other Male XLR, connect the ring of the stereo jack (which sends signals) to a
male XLR pin2. Short here pin 1 and 3 and solder to ground (sleeve). This has
to be done because the insert is not balanced. See below the cable type you
need.
MIC
The Mic input is a professional balanced input circuit with 48 volt phantom
powering for condenser mikes which deliver studioclass microphone quality to
your announcer/DJ channel.

A I R E N C E – U S B M a n u a l P a g e 36
Introduction
Besides the audio channels the Airence mixer is equipped with a control
section. This control section is located at the right of the mixer and
consists of 24 illuminated switches and a rotary encoder with push switch. The
switches are able to illuminate red, green, and yellow to indicate various
conditions. Each switch contains a label which can be customized to customer
needs.
Why a control module?
A frequently desire in the broadcast world is to control specific play-out
software by an external hardware device since the user prefer to have direct
and accurate control over the controlled application. In order to be able to
control such a software application from unlike mouse or keyboard, one
normally needs an external hardware device which is user friendly to operate
and is able to communicate with the relevant application. The Airence mixer
benefits from an integrated control module whereby investments in external
equipment are unnecessary. The control section provides a sufficient number of
switches to control any play out software, for example starting and stopping
jingle players. With the rotary encoder at the top one is able to scroll
through and select parameters.
Figure 1. Airence Control Module
A I R E N C E – U S B M a n u a l P a g e 37
USB channel controls
Furthermore, the fader start, on and cue signals of the four available USB
channels in the Airence mixer could also be used to trigger or control any
software application. In combination with the control module the Airence mixer
provides a flexible all-inone solution to manage and control specific play out
systems.
Figure 2. USB Channel Controls
How does it work? Communication Interface
The present USB bus on the Airence mixer is used as the interface to transfer
all the control signals to the PC. In order to keep things simple the HID
(Human Interface Device) protocol is used for communication between the
Airence mixer and PC. On top of the HID protocol there is specific control
protocol developed at D&R which is discussed in depth in the chapter “Airence
USB HID Control Protocol” for those who wants to go “deeper”.
Update rate
When a state change of a control signal (switch, fader, encoder) occurs, the
current state of all the controls are transmitted to the PC. Such a state
change of a control signal is called an event. The state of a switch can be
pressed or released. In case of an encoder the additional states besides the
pressed and released ones when pushing the encoder (switch function), are
increments or decrements when turning.
A I R E N C E – U S B M a n u a l P a g e 38
Controlling your software application
In order to be able to control a software application (i.e. play out software)
with the Airence control signals (control module / USB channel controls), one
can choose one of the two available methodologies as can be seen in the figure
below.
The first method is most applicable for software developers of the controlled
application, who are able to integrate the Airence USB HID Control Protocol in
their application. For more information about the protocol refer to the
Airence USB HID Control Protocol chapter at the end of this document.
The second method uses a `mapper-application’ in between the HID messages and
the controlled application and is created for the end user. The Virtual
Keyboard Mapper maps the control signals coming from the Airence mixer to
standard keyboard keystrokes. In such a way pressing a switch on the control
module will lead to a customized keystroke which controls a specific function
inside the controlled application (play out software) for example.
· Method 1 (developer):
– Direct access to control messages – Full duplex: read control signals / control LED’s inside the switches – Programming is necessary to integrate the protocol in the application
· Method 2 (end user):
– Easy to use (No programming for integration in application needed) – Half duplex: read control signals – Quick started using the Virtual Keyboard Mapper features
Figure 3. Airence control signal flow A I R E N C E – U S B M a n u a l P a g e 39
Airence virtual keyboard mapper
The Airence virtual keyboard mapper is a software application which maps
incoming control signals from the Airence mixer to keystrokes by creating a
virtual keyboard on a windows machine. Since the mapper application behaves
like a real keyboard it is able to control any software application which is
controllable by a keyboard. Most software applications have attached
keystrokes to file menu items or application specific functions. All the
incoming control signals from the Airence mixer can be individually mapped to
such predefined keystrokes.
Figure 4. Airence virtual keyboard mapper, Windows-based application
Control signals
In total there are 39 control signals coming from the Airence mixer which can
be mapped to keystrokes using the Airence virtual keyboard mapper application.
These 39 control signals are divided into the Control Module signals and USB
Channel controls. Control Module:
Switches 1..24 Encoder switch Encoder increment Encoder decrement USB Channel
Controls: Cue (4x) On (4x) Faderstart (4x) Each control signal may generate a
press or release event (except the encoder) which can in turn trigger two
separate keystrokes. Especially for the USB Channel Controls (latching
switches) it can be useful to control two functions when pressing(P) or
releasing(R) the switch. For example: USB1 ON (P) Ctrl+Alt+F1 (function X in
controlled application) USB1 ON (R) Ctrl+Alt+F2 (function Y in controlled
application)

Setting up your configuration
The Airence virtual keyboard mapper application can be split up in an
configuration editor and configuration viewer section as can be seen in the
figure above. In the configuration editor section one is able to attach
keystrokes to the control signals. To do so, clicking on one of the switches,
encoder or faders opens up a keystroke configuration editor window where the
configuration of the relevant control signal can be done. Configuring another
control signal can be achieved by selecting one from the Source Select
selection box, or by clicking on the relevant control signal on the main
window.
Figure 5. Editor window for mapping control signals to keystrokes
Source Select
At the top of this window one can see a selection box where the control
signals are listed under Source Select. When clicking on one of the control
signals at the main window the Keystroke configuration editor automatically
selects this control signal (source) in the selection box. All settings in
this window are related to the selected source.
Source Action
In the two action field groups the press and release events of a control
signal can be configured. If there is a play out plug-in selected at the main
window you can choose from predefined functions of that specific play out
software. When selecting one of those functions the remaining fields will be
filled in automatically. In such a way that you don’t have to worry about the
keystroke and can focus on mapping a control signal to a play out function.
However, manual changes in the settings after selecting a predefined play out
function is always possible. When no play out plug-in is selected you are not
able to select a play out function from the list and therefore it is necessary
to fill in the fields manually. A maximum of three keys can be configured to
construct a keystroke. Start with configuring Key 1 upwards if more than one
key is included in the keystroke. The keystroke action can be inverted if
required. Finally there is a field to give the action a meaningful name . The
reset button resets the entire configuration for the selected source. The
settings will be stored after pressing the apply button.
A I R E N C E – U S B M a n u a l P a g e 41
Play out plug-ins
An play out plug-in is a set of function descriptions of a specific software
application (play out software) which are mapped to keystrokes. A plug-in is
represented as a standard XML-file which can be seen in the figure below.
There is a plug-in folder PLUGINS created in the installation directory during
setup where the plug-ins are located or has to be placed when creating one.
Present plug-ins in this folder are loaded when Virtual Keyboard Mapper is
starting up. The advantage of using plug-ins will be the ease of mapping a
control signal to a function. You don’t need to worry about the underlying
keystroke of a relevant function since selecting a function from the Keystroke
Configuration Editor will automatically fill in the corresponding keystroke.
These keystrokes are fetched from the plug-in file.
Figure 6. Example of playout plugin file
Create a plug-in
A plug-in is specific for each play out software. If the used play out
software is not available as a plug in you need to create the plug-in
yourself. Since the plug-ins are represented in the XML format (which is
readable for machine as well as human beings) it is not that hard to create
one. It is advisable to use another plug-in as template and modify that file.
In the above figure a basic example plug-in file is shown with two functions.
If more functions are needed simple copy and paste a function block (line 9
16). The plug-in starts always with a block of plug-in information (name,
vendor, version, nfunctions). The nfunctions element contains the number of
functions which are included in the plug-in. After the plug-in information the
functions are listed beneath each other. In the description field the name of
the function needs to be filled in. This name will be used later on in the
Keystroke Configuration Editor to choose a function from the list. Finally,
there is a keystroke element which contains three other elements key1, key2,
and key3 respectively. These last three elements contain together the
keystroke to perform when the function needs to be executed. A keystroke can
consist of a maximum of three keys. Each key element can be filled with a ID
key value between 0 and 91. The ID value represent a key on the keyboard which
can be found in the table in the figure on the next page.

Quick function Learn
The Quick Function Learn is a feature to map control signals to play-out
functions rapidly. First you have to select a play out plug-in before the
quick function learn can be used. If the play out plug-in is loaded correctly,
the loaded functions are listed in the Quick Function Learn box.
Figure 8. Play out plug-in required for using the Quick Function Learn Select
one of the available functions from the Quick Function Learn box and press the
Learn button. The window as seen in the figure below will show up and waits
for a control signal event coming from the Airence mixer. If a control signal
is received the selected function is immediately mapped to this control
signal.

Configuration viewer
In the configuration viewer section an overview of the entire configuration
can be seen. All the pressed and released events of the control signals are
shown in the Virtual Keyboard Mapping area. In order to get a clear overview
the view section is divided into four pages:
Control Module (Pressed) Control Module (Released) USB Channels (Pressed) USB
Channels (Released)
Selecting one of the four pages is done by the radio buttons in the Source
Group Selection and Source Action boxes which are located above the
configuration viewer section.
Figure 10. Page selection view
Let’s get connected
When done with setting up the configuration the Virtual Keyboard Mapper
application is ready to receive changes of the control signals from the
Airence mixer. To do so, you have to press the START button in the Service
box. If the application is able to connect to the Airence mixer the label on
the button would change into STOP and the firmware revision of the mixer is
shown. The indicator near the button indicates incoming messages. Pressing the
STOP button will stop the service and disconnect the Airence mixer. When a
control signal is received and is mapped to a keystroke, this keystroke will
be executed in real time. To let the executed keystroke trigger a function in
a software application you have to take care of giving this application
Priority. An application is only able to receive input when it currently has
the highest priority in your screen activities.

Presets
A preset is a backup of the entire configuration of the control signals with
their mapped keystrokes. Presets can be useful when you want to recall or
store a complete configuration for specific play out software. Presets are
represented as .akp files (Airence Keyboard Preset).
Store preset
Storing the current configuration as a preset can be done by clicking on
File->Save, or File->Save as.
Recall preset
Recalling a stored preset can be done by clicking on File->Open and selecting
the desired preset.
Settings
Under Settings->Presets you can find the preset settings. A configuration
window is shown whereby the default preset directory and the startup preset
can be configured.

HID Control Protocol for software engineers
Introduction
This chapter describes the protocol which is used to communicate with the
control section and the USB channel controls of the Airence mixer. For the
communication between the PC (host) and Airence (device) the USB generic HID
(Human Interface Device) class protocol is used. HID devices are identified by
their PID and VID. For the Airence the PID=0x2402, and the VID=0x03EB. On top
of the HID protocol, a custom message based protocol provides the commands to
send and receive data which will be
described in more detail in this chapter.
Message format
Transmitting data through the USB bus using the HID class protocol is done by
reports. A report always contains an ID and the data inside the report. In
order to successfully communicate with the Airence control section only
reportID 0 may be used. More information about report descriptors can be found
on www.usb.org. For now, remember that the Airence only will listen to reports
with reportID = 0.
A control message has a fixed size of 8 bytes containing a SIZE byte, COMMAND
byte, and a PAYLOAD section of maximal 6 bytes. The SIZE byte contains the
number of bytes used (max. 8) in the message, including this SIZE byte.

Request
A message of the type REQUEST is transmitted form the PC to Airence. The
message is intended to read data from the Airence. After the Airence received
the request it will respond with a corresponding RESPONSE message. Therefore,
a REQUEST message always forms a pair with a RESPONSE message.

2 Background
2.1 USB System Architecture
The USB System Architecture consists of the following main components: · Host
(PC) Computer · One or more USB Devices · A physical bus represented by the
USB Cable that links the devices with the host (PC) computer.
2.1.1 USB Host (your PC) The main responsibility of the host computer is to
control the communication between the host system and USB devices. The host
computer has two layers: a USB host controller hardware layer, and a software
layer, which includes USB device drivers for a wide range of USB devices. The
drivers convert data between the format that is used by the host computer and
the format used by the USB devices. USB hardware layer is responsible for:
· Detecting the attachment and removal of USB devices · Monitoring device
status and collecting activity statistics · Providing power to attached USB
devices · Managing control and data flow between the USB host and USB devices
· Checking the basic validity of bus transactions
USB software layer is responsible for: · Handling USB devices and their
connectivity · USB devices enumeration and configuration · Loading appropriate
device drivers · Managing the power on the bus and bus bandwidth · Managing
the data transfer between the software and hardware
USB Host (PC) Controller A USB Host Controller is the hardware either on the
computer motherboard or PCI card. It provides an interface for transferring
streams of data between the host computer and the USB devices. The host
computer may have one or multiple USB host controllers with different types of
interface.
2.1.2 SB Devices
The USB Devices are peripherals that use the USB protocol for two way
communication with the host computer. The main responsibility of the USB
Device is to provide the end user with various specific functions, such as a
keyboard, a data/ fax modem device, a digital microphone, or a video camera.
For this reason the official USB Specification uses the term “function” to
refer to USB peripheral devices. To provide the user with additional
attachment points to connect more peripherals there is a special type of USB
device called USB Hub.
A I R E N C E – U S B M a n u a l P a g e 52
USB Hub USB Hub is just a device with multiple USB ports for plugging in the
USB devices and other hubs. The Internal root hub in the host (PC) controller
and the external hubs are functionally the same.
2.2 Airence USB System Architecture
The Airence USB System Architecture consists of the following components: ·
USB Hub (for interconnect all the internal peripherals) · 4x Stereo Audio
codec · USB to serial converter (used to transfer metering data) · Control
Section (switches, encoder, faderstart, ON, CUE signals)
Figure 1. Airence USB System Architecture
3 Analysis
When all four audio codecs of the Airence mixer are used simultaneously to
send and receive audio to/from the PC, the USB controller may exceed the
allowed bandwidth of the bus. This problem is noticed in Windows 7 x64
operating system during test phase, but could occur on other Windows versions
as well. If windows detects such a bandwidth overload it will show a warning
message (see figure on the next page). The attached composite device has
requested more than 15% of the available resources of the USB host controller.
Due to the fact the Airence is a composite USB device consisting of four audio
codecs, Control section, USB to Serial converter and USB Hub there is a lot of
USB traffic between the Airence and your PC, if all individual components are
used at the same time. Each USB device which is connected to a port on the PC
will be attached to a root hub which is connected to one of the available Host
Controllers. The root hub may consist of multiple ports, which could be the
case in your system. If more devices than the Airence are connected to the
same root hub the devices need to share the resources and therefore a data
traffic problem may occur.
A I R E N C E – U S B M a n u a l P a g e 53
Figure 2. Windows 7 generates warning message
Figure 3. USB View: Visualize the USB System Architecture A I R E N C E – U S
B M a n u a l P a g e 54
4 Solution
Figure 4. Connect the Airence exclusively to the Root Hub In order to prevent
the bandwidth overload, simply make sure the Airence is exclusively connected
to a Root Hub (see figure above). To do so, a software program called `USB
View’ is used here to visualize the USB tree structure in your system. With
this tool you are able to check if the Airence is exclusively connected to a
root hub. If not, you will see other devices connected to the same Root Hub.
A I R E N C E – U S B M a n u a l P a g e 55
In the example below you can see the Airence is connected to the first port
(LOC21) of a 2-port roothub. There is no device connected to the second port
(Loc22). Therefore, the Airence does not need to share the USB bandwidth with
other devices. To recognize the Airence device you can try to identify the
internal USB Hub with the aid of the vendor- and product id’s, 0x0451 and
0x2077 respectively. Try to connect to another usb port on your PC if the
Airence shares a Root Hub with other devices.

Introduction
Every now and then new firmware versions will be released to provide the
Airence mixer with new features or solved bug fixes. In order to be able to
update the current firmware residing in the Airence mixer a special operating
mode called `bootloader mode’ must be entered to receive new firmware. When
powering up the mixer in an ordinary way it will enter the normal operation
mode and is ready for use.
Bootloader mode
To enter the bootloader mode a special startup sequence should be followed: 1)
Disconnect power 2) Push and hold down the encoder switch (located on the
control section) 3) Connect power 4) Release the encoder switch
Installation Airence Firmware Updatetool
An Airence Firmware Updatetool is available which is required to perform the
firmware update. You can download the installer from the D&R website
(www.d-r.nl)

A I R E N C E – U S B M a n u a l P a g e 62
USB bootloader drivers
When the Airence mixer enters the bootloader mode it will probably sign up as
an unknown device’ in the device manager from Windows. To determine if this unknown device is the Airence in bootloader mode, right-click on the device and select properties. On the Details tab select Hardware-id’s from the properties selection box and verify the VID and PID of the device. VID (Vendor ID): 03EB PID (Product ID): 2FE4 To install the drivers right-click on the device and select update drivers. The drivers can be found in a subdirectory
usb’ of the Airence Firmware
Updatetool installation folder. For example:
C:Program Files (x86)Airence Firmware Updatetoolusb
A I R E N C E – U S B M a n u a l P a g e 63
If the installation of the drivers was successful you should be able to see a
screen similar to the one below: In the device manager the unknown device is
correctly installed and now shown as : ATxmega32A4U The ATxmega32A4U device
indicates the Airence is in bootloader mode.
A I R E N C E – U S B M a n u a l P a g e 64
Firmware Update Procedure Preparation
Before you can start with the update procedure the following precautions must
be taken: – Connect a USB cable between the Airence mixer and the PC – Startup
the Airence mixer in bootloader mode – Download the latest firmware from
www.d-r.nl (e.g. airence_firmware_v1_4.zip)
Flash firmware into device
– Startup the Airence Firmware Updatetool application. – Select the firmware
(*.hex) from the extracted zip-archive downloaded from the website. – Press

certain amount of time to sign up and enumerate the device in the device
manager after starting up the mixer in bootloader mode.
