INTRODUCTION

The AIRMATE-USB has four types of modules to choose from

Triple Input Modules (positions 1-4/8) have the following features

• Professional low noise balanced Mic pre-amp with 48 volt phantom powering.
• Two pairs of line inputs with optional R.I.A.A. equalized pre-amp on line-B for turntables.
• Gain control
• Three band stereo equalizer
• Start (ON) switch
• Stereo CUE switch for pre fade listening
• 100mm smooth professional faders

Input modules 5 &6/9&10 are identical to triple input modules 1 thru 4/8 except for the line-B inputs have been converted into digital USB input and output to allow easy interface with PC’s (Windows & Macintosh computers). This feature will allow you to connect to the Internet via your computer for “Live” streaming of audio to the Internet.
Input modules 7 & 8/11&12 have a high quality built-in Telephone Hybrid in each module which are switchable to stereo line inputs when only one or no Telephone Hybrid is needed in your live broadcast studio.
You can also have ordered VoIP modules and/or Bluetooth modules or any combination of Telco/VoIP/Bluetooth modules.

TRIPLE INPUT MODULES 1-4/8

The input modules switches & controls have the following functions:
Each of Modules 1 thru 4/8 has three selectable inputs. The three types of inputs consist of a Mic input and two pairs of stereo line inputs. 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 B stereo inputs which allows for the module to become a stereo module with both left & right signals to feed the stereo mix buss.

GAIN
With the gain control, the source input level can be adjusted to the required internal mixer level. This control adjusts both the Mic input and the two pairs of line inputs with the same control depending on the switch positions. Mic gain can be increased by 20dB by internal jumper settings (if needed).
STEREO LINE (A B)
The stereo line inputs (A or B) pairs are high impedance inputs for connecting the stereo line level outputs of devices such as CD players.
MIC
The Mic input has a balanced XLR input connector with 48volt phantom powering for condenser mikes. The Mic-pre circuitry uses the latest technology studio- class components. The low-noise design and excellent phase spec that D&R is known for is integrated throughout the AIRMATE-USB.

Using balanced microphones & cables allows for the quietest and high quality audio signals throughout your Airmate-USB mixer. You can use standard balanced Mic cables available at any pro audio dealer or music store.
The Airmate 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.

• AUX SEND
  The next control is a stereo Aux send that sends stereo source signals to the stereo Aux send buss Master 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.

• 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.

• 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.

• FADER
  Final control is the high quality, 100mm long throw K-Alps stereo channel fader with integrated fader start switch. At the beginning of the fader movement you will feel 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 above. A Red light is activated if the SELF OP switch in the master section is activated. Control Room monitoring will be muted when a Mic is opened (DJ setting).

• INPUT CONNECTORS
  On the back of modules 1 thru 4/8, you find seven connectors for each module.
  The Mic input is a balanced female XLR type connector. The two pairs of stereo line inputs use Cinch pro RCA female type connectors. If you use turn tables and need phono type R.I.A.A. equalized pre-amps, D&R offers an optional plug- in R.I.A.A. pre-amp for Line inputs B at a nominal price. The level can be set with the gain control to match any available phono cartridge.
  Both Line inputs A & B are identical with the exception of the optional phono pre-amp. Being unbalanced, the shield and (-) or common need to be connected together 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 (continuesly or momentary by jumper selection) when the ON switch or fader switch is activated. Once you have done this, you can start a turntable with the ON switch (if the START connector is wired on the back panel).

NEVER CONNECT AC POWER VOLTAGE TO THIS REMOTE-JACK

The START jack switches “quick start turntables” through the remote jack via a shorted contact action in the ¼” stereo connector on 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 it can be used as a pulse start switch. This done on jumper J17
It is also possible to use this START jack for local ON-AIR signaling, you need to change jumper setting J11
Connections on the START connector can only be made with a maximum of 24 Volts 50 mA. Please contact your dealer if you are uncertain.
Recently (since mid February 2024) the internal circuitry is modified to accept a Studio Remote unit for Head-phones and Cue communication while muting the Channel signal to the program buss at the same.
NEVER CONNECT AC POWER VOLTAGE TO THIS REMOTE-JACK

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 be the ultimate announcer/DJ sound.
The Ring of the stereo jack sends the channel signal and the Tip accepts the return signal.
On the next page you see the type of cable you need.

• If you are going to make a cable yourselves, do it like this.
• 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 Airmate’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 ty to ground (sleeve). This has to be done because the insert is not balanced.
  See below the cable you need.

SPECIAL OPTIONS FOR MODULES 1 – 4/8

Located on the input channel circuit boards are several jumpers that can be changed to enable different configurations of the channel settings. If changes are required, we advise you to contact your local dealer to have these changes performed.
The following 7 jumper settings can be changed to adjust the Airmate-USB to your needs.

Jumper J12 and J13. Underneath the small pcb you look at.
J3| Low cut ON| Low cut filter on Mic input done by shorting all 4 pins on Jumper J3.9
J15| Phantom ON| 48 volt phantom power on/off via Jumper J15.
J6/16| POST| Stereo Aux send pre or post selectable via Jumper J6/16
J7| Channel 7-8 ON| Clean-Feed (CLN-FEED) jumper (J7) to select whether the stereo audio signal(summed to mono) is sent to the clean-feed bus that is available in the master section for connecting external Hybrids.
J17| Continuously| Pulse/Continuously Jumper J17 to change the start pulse from latching (continuously) to pulse.
J5| 20dB| Mic gain ( Jumper J5) can be set to change the Mic pre from 20dB to 40dB of gain.
J10| MIC ON| This jumper enables you to mute the control room monitor when the line input is selected. (in case a mic processor is connected to the line input) 1+2= Mic mutes CRM.

2+3= Mic + Line mutes CRM. No jumpers = no CRM mute.

J11| FDR Start with Mic input (OFF)| You can use the START jack to individually switch on an ON-AIR light that shows that this channel MIC is active. The main ON-AIR jack in the master section will also be activated. Reposition Jumper J11 from off to ON
J9/J18/J19| Faderstart or Studio Remote| On all three jumpers set 1+2= Faderstart (default) or 2+3=Studio Remote
J20| GPO| 1+2=GPO no jumper is no GPO

USB-LINE MODULES 5/9 AND 6/10 CONNECTORS, CONTROLS, & FUNCTIONS

• Low noise balanced Mic pre-amp with 48 volt phantom powering.
• One pair stereo line inputs (left & right)
• One USB connector (stereo in & out)
• Gain control
• Three band equalizer
• Stereo CUE switch for pre fade listening

GAIN
With the gain control, the source level is adjusted to the required internal mixer level.
This is for both Mic/Line inputs as well as the USB inputs.
LINE – USB
The stereo line input is a high impedance input for connecting any stereo line level device such as CD players, iPods, tape decks etc. The USB switch changes the module into a USB in and out module. The USB connector will communicate with play-record devices such as computers using a DAW (Digital Audio Workstation), Windows Media Player, and/or CD players using a USB output connector. It is an input that can be connected to any standard USB connector on PC’s to make an easy interface with music programs running on the PC. When the USB connection is made between the Airmate-USB and your PC, your computer will recognizes the USB device as new hardware. A small green led lights when data is sent over the USB cable.
In Windows Media Player, you can change settings to allow it to work as a player or recorder.
The controls of the input modules have the following functions.
MIC
The Mic input is a professional balanced input circuit with 48volt phantom power for condenser mikes which delivers studio-class microphone quality to your announcer/DJ channel.
EQUALIZER
Each input module has a three band equalizer to control the high, mid, and low frequencies individually at carefully chosen frequencies.
AUX   SEND
Below the Equalizer is the stereo Aux send control that can send mono Mic or stereo source signals (pre or post fader via PCB jumper settings) to the stereo Aux Send buss. The factory default is post fader.
CUE
Below the Aux send is the stereo CUE switch (Pre Fader Listening), this switch allows you to check the signal before you mix it with the other signals in the Airmate-USB.
ON
The ON switch is used to make a connection that can start turntables and CD players as well as jingle or cart machines. This switch sends out a momentary pulse or switches continuously inside the Start connector on the mod-ule back plate at the rear of the mixer. See “Start switch” on page 4.

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 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 your AIRMATE-USB modules 5/9 and 6/10 you will find the following five connectors.
• Two unbalanced line 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 USB connector is wired according to International standards and is a stereo USB 2 Codec (HID Interface) digital input, as well as an output.
• 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.
The balanced Mic input is on XLR and can provide 48volt phantom powering.

SPECIAL AVAILABLE OPTIONS IN YOUR AIRMATE-USB MODULE
On the input PCB of your AIRMATE-USB module there are several jumpers that can be changed to enable different configurations of the channel settings. This should be done by a D&R dealer or service center.
The following 8 jumper settings can be changed to adjust the Airmate-USB to fit your needs.

default).
5| J7| Clean-Feed (CLN-FEED) jumper (J7) to select whether the audio stereo signal

(summed to mono) is send to the clean-feed bus that is available in the master section for external Hybrids.

6| J17| Pulse/continuous Jumper J17 to change the start pulse from latching (continuously) to pulse.
7| J5| Mic gain ( Jumper J5) can be set to amplify an extra 20dB or 40dB.
8| J28-32| USB output selection to select pre-or post master fader. (if your mixer has a with a master- fader)

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 a post master stereo fader signal that is sent to the USB connector. You can change this by moving both yellow jumpers to the mid positions, now you have a pre-fader signal going to your PC. A mix is also possible of course. The level is set by the master faders of the mixer when post is selected. But you also have left and right of the jumper settings two trimmers (VR1 and VR2) that adjust the level that is sent to the USB chip in the
• Airmate and thus adjust the outgoing level to your PC for left and right signal pre or post master faders.
• This is especially important for Windows 7 that recognizes the Airmate-USB chips we use as mic level signals.
• A lower output level coming from the Airmate-USB will greatly improve performance. 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 https://www.darkwooddesigns.co.uk/pc2/testgen.html
• To be able to adjust this level you need to remove the bottom plate of the Airmate to access the trimmers.
• The return signal coming from the PC is fixed but can be adjusted with the Gain control of the Airmate-USB channel.

SETTING UP THE USB MODULES
Previous discussions about modules 1 thru 4/8 is also applicable for modules 5/9 and 6/10 except in these modules line B is replaced by a USB interface circuit and connector.

In order to set up a connection between your computer and AIRMATE-USB mixer, use a standard USB cable from any local computer shop. (See picture).

Standard USB cable

When connecting the Airmate-USB to your computer, the computer (PC or Mac) will recognize the Airmate 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 com-
plicated setup routines, just plug in the USB cable to your Windows or Mac computer and start tracking!

TELCO-LINE MODULE 7/11 and 8/12 CONNECTORS, CONTROLS, & FUNCTIONS

Input modules 7/11 & 8/12 have integrated Hybrid circuitry with built in high quality Telephone Hybrids as well as stereo line inputs in case only one Hybrid is needed.

Highlights are

• High quality Telephone Hybrid circuit to directly connect to phone lines
• Stereo line input
• Gain control
• Telco send Control
• Direct access CONNect and TB (Talk Back) switches
• Stereo Aux send
• Stereo CUE switch for pre fade listening
• Start (ON) switch
• 100mm smooth professional faders

WHAT IS A TELEPHONE HYBRID?
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 un-wanted signal, they facilitate two-way communication when using a single 2 wire telephone line.
Each Airmate-USB hybrid module has a Telephone line (WALL) connection and a handset connection.
Thousands of D&R Telephone Hybrids (also built into this Airmate-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 : Internally connected in the Airmate.
• Input : Line level 0 dBu balanced, internally connected in the Airmate.
• R/C balance : fully adjustable.
• Separation : more than 30dB.

The controls of the Hybrid/Line modules have the following functions.

TELCO SEND
With this control you adjust the level of the outgoing signal to the telephone line.
TELEPHONE HYBRID / STEREO 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 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.
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.

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.
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.
RING (LED)
This LED lights to alert you when a call comes in.
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.
ON
The ON switch is used to activate the module and generate a signal to start turntables, CD players, and cart or jingle machines. This switch sends out a momentary pulse or switches continuously to the Start connector on the back of the console. When used on either of the Hybrid modules, any other function needed can be activated.
FADER
Final control of the signal in either of these modules is the 100mm channel fader. With the fader you can send the amount of signal from this module to be mixed with the other signals feeding the outputs whether the need is live streaming or recording for production. At the beginning of the fader movement you will feel the internally built in start switch that is activated when you bring up the fader. This switch activates the start circuitry which can control externally connected (via the Start Connector on the back) devices such as CD players, turntables, etc.

INPUT CONNECTORS

• On the back of each of the AIRMATE-TELCO modules 7 and 8 you find five connectors.
• Two unbalanced stereo line RCA Cinch connectors for connecting CD players, iPods, or any play-back 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 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 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 the 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 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 TELCO Module to the telephone landline (Wall) and to your Telephone set so you can dial out to people you want to interview or pick up incoming calls from your radio program listeners.RJ11 type of cable that can be used to connected both the Telephone set and the mixer and the mixer to the wall outlet

SPECIAL AVAILABLE OPTIONS IN YOUR AIRMATE-TELCO MODULE
On the input PCB of your AIRMATE-USB module there are several jumpers that can be changed to enable different configurations of the channel settings. This should be done by a D&R dealer or service center.
The following 4 jumper settings can be changed to adjust the Airmate-USB Telco modules to your needs.

1| J6/16| Stereo Aux send pre or post selectable via Jumper J6/16 (post is default).
---|---|---
2| J7| Clean-Feed (CLN-FEED) jumper (J7) to select whether the audio stereo signal

(summed to mono) is sent to the clean-feed bus (available in the master section for ex- ternal Hybrids).

3| J17| Pulse/continuous Jumper J17 to change the start pulse from latching (continuously) to pulse.

CONNECTION WIRING OF BOTH (Wall) LINE and PHONE RJ-11 CONNECTORS

VoIP-LINE MODULE 7/11 and/or 8/12, CONNECTORS, CONTROLS, & FUNCTIONS

Input module 7/11 and/or 8/12 are dedicated Voice over IP Telephone module and also have a stereo line input in case a classisc Hybrid is needed.

Highlights are:

• High quality Telephone Hybrid circuit to directly connect to the Internet.
• Stereo line input.
• Gain control.
• VoIP/Telco send Control.
• Direct access CONNect and TB (Talk Back) switches in the master section.
• Stereo Aux send.
• Stereo CUE switch for pre fade listening.
• Start (ON) switch and 100mm smooth professional fader.

VoIP-CHANNEL
In the AIRMATE-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 channel 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).
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 signal from the cleanfeed output on the back of the console.
TELEPHONE/LINE SWITCH
When switched to the VoIP (Phone) up position only the VoIP signal is received. When this switch is down, you have a high impedance stereo line level input for connecting an external Hybrid or… cart machines, iPods, tape machines, CD players etc.
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)
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. You can of course have a handset with the possi-bility 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 the fader.
TALKBACK
By pushing the TB switch on the VoIP module, the internal talkback microphone is activated and allows you to talk to the caller without being ON-Air.
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.
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. 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 in-dicator 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 an 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 connection on the back).
INPUT CONNECTORS VoIP (Telco2 Telco1)
On the back of each of the AIRMATE-VoIP(TELCO) modules 7/11 and 8/12 you find five connectors. Two unbalanced stereo line RCA Cinch connectors for connecting CD players, iPods, or any play-back 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 use this connector to activate an external ring indicator such as our D&R PHONE light.

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.

USB CONNECTOR
The bottom RJ11 connector (Phone) is replaced by a USB connector to directly communicate with your PC (internet) via a USB cable connected to a spare USB connector on your PC.

CLEANFEED OUTPUT
The top RJ11 connector (WALL) now provides you with a cleanfeed signal on pin 1 and 4 to connect to an external Hybrid.

BLUETOOTH HYBRID CHANNEL
The Bluetooth module for the AIRMATE-USB uses our high quality Telephone Hybrid circuit to enable you to make calls on your Bluetooth enabled device during your broadcast. It also supports high quality Bluetooth audio, so playing music on your AIRMATE-USB has never been easier.

CONNECTING TO A BLUETOOTH DEVICE
Once the AIRMATE-USB has been switched on, the Bluetooth Hybrid will be in standby mode. The blue LED will be off.

• Press and hold the CONN button to enable pairing mode. The blue LED will start blinking.
• On your Bluetooth enabled device, search for “D&R AIRMATE”. Click connect.
• When a connection is successful the blue LED on the Bluetooth Hybrid will stop blinking and stay on.
• If no action is taken the Bluetooth Hybrid will automatically go out of pairing mode and into standby mode after 30 seconds. The blue led will stop blinking and go off.

Now that the Bluetooth Hybrid and your other device have been paired, the next time the AIRMATE-USB is switched on the Bluetooth Hybrid will automatically search for known devices and connect to it.

DISCONNECTING A BLUETOOTH DEVICE
Press and hold the CONN button.
The Bluetooth Hybrid will disconnect from the current device and go into pairing mode.

TAKING A BLUETOOTH CALL
Once connected to the Bluetooth Hybrid you can now take calls on your AIRMATE- USB (if the other device supports Bluetooth HFP/HSP).

• When you are being called the RING led will blink. You can pick up the call by pressing the CONN button. The green CONN led will be lit. Note: the incoming call will not be heard until the CUE is pressed or the ON switch and the fader are ac¬tivated which brings the signal to the mixer. 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 the fader.
• When a call is active, to disconnect the call press the CONN button again. The green CONN led will be off.

BLUETOOTH AUDIO
Once connected to the Bluetooth Hybrid you can now play music on your AIRMATE- USB. Choose your favourite player (Playout software, Spotify etc.) and press play on your device.

It is also possible to play/pause music using the CONN button on the AIRMATE- USB. When music is not playing the CONN button will play music, when music is playing the CONN button will pause the music.

• BLUETOOTH HYBRID SEND
  With this level control the outgoing signal from the mixer is sent to the caller via Bluetooth Hybrid. This is for both the Bluetooth Hybrid and the Stereo Line input (when selected). This Bluetooth Hybrid gets it send signal from the cleanfeed output on the back of the console.

• TELEPHONE/LINE SWITCH
  When switched to the up position only the Bluetooth Hybrid signal is received. When this switch is down, you have a high impedance stereo line level input for connecting iPods, tape machines, CD players etc.

• GAIN
  With the GAIN control, the source level is adjusted to the internal mixer level. This is for both the Bluetooth Hybrid and the Stereo Line input (when selected).

• TALKBACK
  By pushing the TB switch on the Bluetooth Hybrid module, the internal talkback microphone is activated and allows you to talk to the caller without being ON- Air.

• 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.

• 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. This switch sends out a momentary pulse (de-fault) 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). 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 con¬nector on the back).

• INPUT CONNECTORS BLUETOOTH HYBRID
  On the back of each of the AIRMATE-BLUETOOTH-HYBRID/LINE modules 7/11 and 8/12 you find three connectors. Two unbalanced stereo line RCA Cinch connectors for connecting CD players, iPods, or any play-back 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 use this connector to activate an external ring indicator such as our D&R PHONE light.

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 AIRMATE-USB master section houses all the controls for the mix buss faders and master controls for Aux re-turn, 2-Track play-back, and master outputs. Individual functions are described below.

• LEDBAR METERS
  The master section has two high-res 21 segment LEDbar meters with VU meter Ballistics. Depending on which switch is pressed (Cue on channels, AUX SEND master, AUX RET, 2 TRACK, 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 the yellow area (3 led’s) is the range that normally would be on with the proper amount of signal. Occasionally a red led on is no problem.
  The output of your AIRMATE-USB is +4dBu (1.22v) (“0” VU) when the top green LED is on.

• MASTER 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.

• AUX SEND
  The stereo AUX SEND master controls the sum of the entire individual Aux send signals coming from the input channels.

• AUX CUE
  The AUX SEND CUE switch allows for the master LED bar meters to display the Aux output signal of the Aux mas-ter as well as hear the signal from the AUX buss.
  It is necessary to turn the AUX SEND master control up to create and show an outgoing signal.

• MONITOR
  The MON (monitor) control is fed by the master outputs pre (before) the master faders. 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 MON (monitor) 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 head-phones.

• 2-TRACK
  The 2 TRACK switch allows for playback of the outputs from stereo devices such as CD players, tape machines, computer sound cards, iPods, etc. to be routed to the MON (monitor buss). Its sensitivity is -10dBv (300mV). Note: The Cue system (from anywhere in the mixer) will interrupt the 2 track signal when activated.

• AUX RETURN
  This stereo input is intended to be used for returning the stereo outputs of reverbs or other effects gear and is connected directly to the stereo main mix buss. 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.

• BALANCE
  The balance knob controls the balance between the main stereo 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.

• PHONES
  The phones output (located on the front panel) automatically switches between main mix outs and QUE from any input modules or on the Master section. Normally the left/right output is heard until a Cue switch is activated from anywhere in the console. 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 Ohm set of headphones will produce distortion when crank-ing up the level of the Airmate-USB due to the impedance load is too low. If you must use 8 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 AIRMATE-USB has no power amp.

• MASTER FADERS
  The AIRMATE-USB master faders haven been removed by request of many custmomers.

• SELF-OP
  This switch mutes the monitor output (control room monitor speakers) as soon as a microphone input is opened. At the same time a relay is activated which is connected to the Red Light out-put connector.

• CLEANFEED OUTPUT
  The Clean feed output sums all signals coming from the input modules (except for those inputs where jumper J7 is not activated). Clean feed signals are equivalent to Aux send signals, but are always post fader. By jumpering only those channels that are not returning Telephone Hybrid signals you avoid feedback and have a perfect set-up for talk shows. The Clean feed output is only used when an external Hybrid is used.

• CLEANFEED
  All outgoing signals from the Clean feed output can be monitored via the Cue system.

• ANNOUNCER OUTPUT
  In the up position of the “follow phones” switch, the input of the announcer is fed by the main left/right signal pre master fader. In the depressed mode of the “follow phones” switch, the Announcer output is fed via the same signal as the phones output.

• FOLLOW PHONES
  This switch is the input selector of the announcer output, see above description.

TALK BACK
The Talkback 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.
The Talkback level is independent of settings of the master controls, the Clean feed, and Announcer outputs. It is however put through the master level of the master Aux output control. The Talkback switch has a momentary action to avoid being in the talkback mode when not wanted.

• MASTER CONNECTORS
  The master connector panel houses 12 RCA Cinch connectors, 2 jack sockets, and 2 male XLR connectors. The electrical mains connector with integrated fuse holder is located in this section.
  A ground terminal completes the back panel connector section.

• TAPE OUTPUTS
  The tape output connectors are left and right outputs for connecting to the inputs of a stereo audio recorder or any other analog or digital device. Output level is -10dBv (300mV), the signal is pre master fader.

• CLEANFEED OUTPUTS
  Direct beneath the Tape outputs are the Clean feed RCA cinch output connectors.

• MIC ON
  Directly beneath the Clean feed RCA cinch connectors is a stereo jack socket (Mic On) that can control a red light indicator. This stereo jack is connected to an opto coupler. This opto coupler can pull down (or shorten the tip and ring of a connected stereo jack and can controlling external Red light circuits as long as it doesn’t take a higher voltage than 24 volt and the current doesn’t exceed 50mA! Please have look at our ON-AIR light that can be switched on with a simple 2 wire connection. Look at http://www.d-r.nl/on- air-light.html

• NEVER CONNECT 115/230 AC VOLTAGE TO THIS JACK!!
  The Tip is connected to the Opto coupler.
  The Ring is also conencted to thte opto coupler.
  The Ground is not connected.

AIRMATE-USB MIC-ON LIGHT / START EXAMPLES

For our AIRMATE-USB SMD models
Only the tip and ring of the MIC-ON master jack are used in the smd version.
An opto coupler shortens the Tip with the Ring (of a stereo jack) to control ON-AIR lights connected.
Note: Our latest D&R ON-AIR warning light design does not need an external relay. Just 2 wires from the MIC-ON control output jack (tip-ring) of your AIRMATE-USB to the barrier strip inside the ON-AIR lamp and that is it!

• 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 -10dBv as a minimum.

• AUX OUTPUTS
  The aux outputs are on two RCA Cinch connectors with the signal coming from the aux send controls in the channels. The level is +4dBu (1.22 volt).
  You can connect the inputs of reverbs from these outputs or use them as a monitor output, after you jumper the Aux send in the channels to pre fader.

• 2-TRACK INPUTS
  These inputs are intended to return stereo machines in the monitor section.
  Such as signals from master recorder/tuners etc. The level needs to be -10dBv (300mV) as a minimum for optimum signal to noise.

• MASTER OUTPUTS
  The master outputs are 3 pin male XLR connectors and are ground compensated balanced with all the advantages of balancing are maintained when connected to a balanced input of a power amp, professional recorder, or On-Air processor. The output level is +4dBu (1.22 volt).

• GROUND CONNECTOR
  This terminal can be used for grounding Phono players as well as the central ground point in a complex installation set-up.

• MAINS CONNECTOR
  The mains inlet is a Euro type connector with built in fuse. Your AIRMATE-USB can accept voltages between 210 volts and 230 volts 50/60Hz or with the proper modification for 120 volts. When using the Airmate-USB at 220 volts, a 1 amp slow-blow fuse should be used, however, when using the mixer at 120 volts, a 2 amo slow-blow fuse should be used. Consult with your local dealer or D&R Service Center for power supply modification to change from 220 volts to 120 volts AC. Never replace either fuse with a higher value.

OPTIONAL MASTER AES/EBU XLR CONNECTORS
If you have chosen to order digital outputs on your mixer the master AES/EBU XLR’s will be your digital in and out-puts to go fully digital to the transmitter or other broadcast devices connected to the AIRMATE-USB.
As you can see in the picture below there are 2x 3 pin male XLR connectors, normally providing you with ground compensated balanced analog outputs that give the main program stereo signal, but now these are converted into a balanced digital AES/EBU standardized output signal (XLRE male) and… as a bonus you get also the possibility for accepting digital AES/EBU signals on the second XLR (female).
Above these XLR’s are 2 stereo jacks that also signals out the main program signal, labelled Output Right and Out-put Left, in case the main outputs are converted to digital there will always be analog outputs available.
In case you have ordered a digital stereo output on the mixer the AES/EBU output is wired to the Left male XLR indicated by the reversed text AES OUT. Levels can be adjusted internally if needed.
The other Male XLR now becomes the AES/EBU input and that digital stereo signal can be routed to the 2 Track inputs by setting a jumper and then connected to any input of the console with a stereo cable from these 2 TRACK cinch sockets to any line input. The 2 Track button on the front allowd pre- listening of these input signals.
All the rest of the connectors are unchanged in function.

NOTE: In the standard (non digital) AIRMATE-USB the jack output jacks are not available

OPTIONAL MASTER AES/EBU XLR CONNECTORS
Below you see one of the master boards with the digital pcb mounted.
On the left side of this small pcb you see jumpers. Now they are jumpered as default that the digital input signal is NOT routed to the 2 Track cinch connectors. If you want that, you have to move both jumpers from the right position to the left position.
Below these 2 jumpers you see 2 blue trimpots that can change the level of the digital outputs.

SET-UP ROUTINES MODULE 1-4/8

• Connect a power-amp, recorder, or transmitter to the left/right outputs.

• Connect a high impedance headphone to the “phones” jack socket on the master section.

• Connect the microphones as described.

• Now, connect turntables, CD players, and jingle machines.

• If more than 2 Telephone Hybrids are needed, you can connect another Hybrid to the Clean feed output.

• Be sure that Jumper J7 is on position 3-4 to avoid feedback when returning the Telephone Hybrid output on the channels.

• Connect a red light indicator when there is a need for it.

• The Announcer output 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 A or B.

• Put on your headphones and turn the headphone volume control to the “12 o’clock” position.

• Turn all the gain-controls and the master-control off (counter clockwise).

• Set all equalizer-controls to the “12 o’clock” position.

• All pushbutton-switches should be in the up position. (See above).

• Switch on the power-supply, 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 LEDbars in the master section.
• You can change the input sound by adjusting the equalizer-section.
• If you adjusted 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 jumper on J5 (on the channel PCB)should be removed to get an extra 20dB of gain.
• The LEDbar indication should be between 0 dB and +6 dB (the yellow area) 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 +4dBu output level.
• Release the CUE switch so the led bar now reads the output signal again.
• Now push the ON button to connect the input signal to the fader.
• Now move the fader to the “8” position screened alongside the channel faders and turn up the master fader to the “10” position. Further volume adjustments can be made on the equipment your signal is feeding, 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 precise adjustments.

Be carefully not to place the AIRMATE-USB near heavy power transformers such as power amps. Although the AIRMATE-USB is constructed using a thick medal frame, this could cause hum.

SETTING UP THE USB MODULES
Input modules 5 & 6 are identical to triple input modules 1 thru 4 except for line-B input is replaced with a USB (stereo input and output circuit) connector on the back panel.
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 Airmate-USB to your computer, the computer (PC or Mac) will recognize the Airmate 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!
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.

SETTING UP THE TELCO MODULES

Connect the two wires of the telephone line’s wall unit to the RJ-11 connector labeled wall (LINE) and connect the telephone appliance itself to the RJ-11 connector labeled PHONE. Note that to originate calls, a local phone must be connected to the Airmate-USB.
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 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.

• Adjust the Telco send potentiometer to increase or decrease the outgoing level to the caller.
  Note : This is all happening outside of 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 “8” 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.

• These adjustments are only required once when installing the Airmate-USB.

• 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.
