PRODUCT DESCRIPTION / PRECAUTIONS
AP4.9 bit is an amplifier featuring 4 channels settable into bridge mode, with
a 32-bit, 147-MHz digital signal processor (DSP) and 24-bit Analog-Digital and
Digital-Analog converters, essential to optimize the acoustic performance of
your Car Audio entertainment system. It connects to any OEM system, even in
vehicles with built-in audio processor, since the AP4.9 bit sends back a
linear signal thanks to the De-Equalization function. It features 7 signal
inputs, 6 Hi-Level and 1 S/PDIF optical digital, and provides 4 amplified
outputs and 5 booster outputs for an analog amplifier, to offer a 9-channel
amplified system. Each output channel features: a graphically adjustable
parametric equalizer group, a 68-step frequency electronic crossover as well
as BUTTERWORTH or LINKWITZ filters with 6-24 dB slopes and a digital time
delay line. The user can adjust the AP4.9 bit settings through the DRC remote
control device.
WARNING: 1. a PC provided with Windows XP, Windows Vista, Windows 7 or Windows
8 operating system, 1.5 GHz minimum
processor speed, 1 GB RAM minimum memory and a 1024 x 600 pixels minimum
resolution graphics card as well as at least 512 MB of available hard-disk
space are required to install the software and setup the product. 2. Before

1 POWER.
+ Power (11-15 VDC): connection terminal for AP4.9 bit power supply positive
pole. The jack accepts a stripped cable up to 15mm/0.6″ with maximum section
of 8 AWG ( 3,2mm / 0.12″). For better power transfer we recommend using cables
with the largest possible cross-section and with the same cross-section as the
cable connected to the negative pole.
– Power (Ground): connection terminal for the negative power supply pole of
the amplifier. Connect here the negative battery cable or a cable connected to
the vehicle chassis. The opening will take a stripped cable up to 15mm/0.6″
with a maximum section of 8 AWG ( 3,2mm / 0.12″). For better power transfer,
we recommend using cables with the largest possible section and with the same
section as the cable connected to the positive pole. In order to correctly
connect the ground (-), use a screw that is already present on the metal part
of the vehicle; If necessary, remove any paint residue or grease, using a
tester to make sure there is continuity between the negative terminal (-) on
the battery and the mounting point. If possible, connect all of the grounds on
the audio components to the same grounding point. This helps reduce most of
the interference than can occur in audio reproduction.
WARNING: Make sure the connection polarity is as indicated on the terminals. A
misconnection may result in damage to the
AP4.9 bit. After applying power, wait at least 10 seconds before turning the
AP4.9 bit on.

coming from the main analog source. Input sensitivity automatically adjustable
from 2 to 15 V RMS (see sec. 7.2.5). Channels FL FR RL RR feature the AUTO
TURN ON (ART) function through connection with the outputs on the source
speakers. This function can be excluded using the PC Software.
Remark: The ACP6 / ACP2 accessory can also be used to interface head units
equipped with PRE OUT output (min. 2V) to the AP4.9 bit inputs. (see sec. 10.2
– 10.3)
2. INPUTS IN1 IN2: Auxiliary signal inputs that can be used when configuring
the unit to reconstruct a multi-amplified signal (Front Tweeter, Front Mid Hi,
Center, Sub) or specialized like AUX inputs (see sec. 7.2.5).
3. REMOTE: – REM IN. Input to turn on AP4.9 bit remotely through the audio
signal source Remote Out. REM IN can be connected to the ignition switch
terminal (ACC). The voltage must be between 7 and 14.5 VDC. If using a source
with a amplified outputs, AP4.9 bit can be automatically turned on (see sec.
7.3.4.7), so it will not be necessary to connect the REM IN terminal.
– REM OUT. Output to turn on other devices/amplifiers connected after AP4.9
bit. From the time it is turned on, it takes 1 second to supply the signal to
the REM OUT output, but it will be possible to set this delay via software
(see sec. 7.3.4.7). The 200 mA output current capability can also drive an
automotive relay.
4. SWITCH INPUTS: – OPTICAL SELECT: It allows the input selection OPTICAL IN
/ AUX IN. This control is active bringing the terminal to +12V and the input
choice to be activated can be programmed using the PC software (see sec.
7.3.4.7), the unit can also be turned on using this terminal.
– MASTER ENABLE: It enables the MASTER input selection. This control is active
bringing the terminal to +12V.

be reproduced. Connect a fiber optic cable with a TOSLINK connector. This
input can be selected using the external DRC control or by activating it using
the OPTICAL IN terminal. (see sec. 5.2)
7 DSP OUT. The AP4.9 bit comes with a 12-pin connector to link 4 analog
signals in the DSP to an Audison AP4 D amplifier or any 4-channel amplifier
(see example 2). The standard product comes with a cable that can be connected
to the AP4 D standard input cable by linking the relays to the inputs,
respecting the colors indicated (see example 1). If you are not using an AP
amplifier this cable can be re-headed with RCA connectors which might be
connected to the amplifier used (example 2). It is also possible to use a
TLC.AP4-1 accessory cable to directly connect the AP4.9 bit to an AP4 D amp
(example 3).

or the type of system you wish to create.
12 FUSE. 30 A blade protection fuse needs to be replaced, use same type and
value as the original.
13 LOGO STATUS. AP4.9 bit has an built-in control that manages its status and
protects the circuits and connections to the speakers. The logo on the AP4.9
bit top cover will change its status in case of any possible product
malfunctions.
A BLUE logo means: AP4.9 bit is on.
A flashing RED/BLUE logo means: The “UPGRADE MODE” switch on the product is
set to “ON” position, or the product Firmware is being updated.
A flashing BLUE logo means: The unit is in stand-by (energy saver) because
there is no audio signal. This function (AST) can be activated using the PC
software. (see sec. 7.3.4.7) and the stand-by time ranges from a minimum of 5
mins. to a maximum of 20 mins. The unit will automatically turn off after 30
mins. when there is no signal.
A RED logo flashing one single time every 2 seconds means: – AP4.9 bit
temperature reached 75° C and the thermal protection was triggered. It will
start operating again at
around 70° C.
A RED logo flashing twice every second means: – Output overload. The red LED
flashes when the output load goes below the minimum allowed capacity of about
2
impedance. The LED comes on without flashing, activating the protection. When
listening to music, if the acoustic reproduction stops for a few seconds,
check if the red amplifier LED is flashing. This means there was an overload.
Turn the amplifier off and check the speakers and wirings. – Speaker wiring
anomaly. The red LED flashes when a terminal on the speaker goes in short-
circuit with the vehicle chassis. When listening to music, if the acoustic
reproduction stops for a few seconds, check to see if the red amplifier LED is
flashing; this means there was a short circuit between a terminal on a speaker
and the vehicle chassis. Turn off the amplifier and check the speakers and
wiring.
A RED logo flashing four times every second means: – The “OVER VOLTAGE”
protection activation, due to the fact that the battery voltage is higher than
16V. The
product will turn off after 3 minutes. WARNING: Check the state of charge of
the car alternator.
A RED logo means: – Product internal fault. You have to go to an authorized
service centre. The product will turn off after 3 minutes.

WARNING: The digital inputs accepts up to 96 kHz / 24 bit stereo PCM signals.
So DOLBY DIGITAL (AC3) multi-channel signals
coming from audio/video sources (such as the audio of a film in DVD) or DTS
can not be reproduced. The output of these devices will therefore have to be
set in STEREO mode for the signal to be reproduced. If digital signals at
frequency higher than 96kHz (Ex. 192 kHz) are supplied, the AP4.9 bit will not
be able to reproduce them.
How to select OPTICAL input: 1.Using the DRC, selecting the OPTICAL input.
2.Using the appropriately set OPTICAL IN terminal (see sec. 7.3.4.7). This
command is active connecting the terminal to + 12V.

7. HOW TO SET UP AP4.9 BIT WITH A PC
7.1 OFFLINE MODE
OFFLINE mode can be used to analyze the software without connecting AP4.9 bit
to the PC to become familiar with the numerous functions of the processor.
(For specific functions, see TARGET mode section 7.2). To activate the OFFLINE
mode, the device must be disconnected from the PC. The software is preset to
start with a 3 way active FRONT + REAR full multi-amplified system. To set a
new “virtual” system and thus change the inputs and select the outputs, select
the function Configuration Wizard in the SETTINGS window of the software main
menu.
Remark: Change the size of the window for the PC software. · To make the
window full-screen, click on the Enlarge button or double click on the title
bar of the PC Software window. · To restore the previous size from full-
screen, click on the Reset button or double click on the title bar on the
window. · To resize the PC Software window (make it smaller or larger),
position the mouse pointer on one edge or corner of the window. When the mouse
pointer becomes an arrow with a double point, drag the edge or corner to make
the window larger or smaller.
28
USER’S MANUAL
AP4.9 bit / 7
7.2 TARGET MODE
In order to configure the inputs, amplified and pre-amplified power outputs,
EQ and time delays for AP4.9 bit, it must be interfaced with the PC. When you
get to this point you must already be aware of what type of system you intend
to set up. In order to change these choices at a later date, you will need to
perform the guided procedure again.
The guided procedure will ask: – The type of specialization for the main input
channels used. The guided procedure changes according to your choice. – The
type of signals that will be assigned to the main inputs (e.g.: Front Left or
Center or Subwoofer, etc.). – The speakers in the system (e.g.: 3 way Front or
Sub Stereo or 2 way Rear, etc.). – If there are passive crossovers that manage
groups of speakers (e.g.: 3 way systems with active midrange). – If you intend
to use an external monophonic amplifier to drive a Subwoofer or an external
amplified subwoofer. – If you intend to use the amplified outputs on AP4.9 bit
in BRIDGE configuration, thus increasing the power on the output.
WARNING: During this operation, we recommend disconnecting the power connector
from AP4.9 bit to the speakers, disconnecting the SPEAKER OUT connection. (see
sec. 4.4)
1. Connect the speaker outputs or the Pre Out outputs from the INPUTS on
AP4.9 bit (see sec. 4.2). Before turning on the system, make sure the power
outputs are disconnected from AP4.9 bit to avoid damaging the speakers during
calibration. The input calibration operation must be performed with the
vehicle engine running. In this case, the voltage is about 14.0 V. The source
will provide an undistorted output signal at higher volume.
2. Turn on AP4.9 bit and connect the USB cable to the PC. Start AP4.9 bit
software by clicking on the icon on the PC Desktop that was created upon
installation.
3. If synchronization is successful, a communication window will appear that shows the data exchange between the processor and software. Wait a few seconds.
4. Click on the Settings menu and select Configuration Wizard. Press Start to continue with the configuration. Press Cancel to exit the procedure.
29
USER’S MANUAL
AP4.9 bit / 7
5. Input Configuration Any of the input channels on AP4.9 bit can be given the name corresponding to the signal coming from the source. Choose one of the following input configurations: – (1) F + R + AUX : controls Front stereo + Rear stereo + AUX input. It is possible to select from the drop-down menu which input sections to use to drive the subwoofer in the audio system. The subwoofer channel /s can be driven either by the input signal coming from the Front line, or by the input signal coming from the Rear line or by the one coming from the mix of Front+Rear lines. – (2) 2 WAY F + R: controls a 2 way active Front stereo + Rear stereo. It is possible to select from the drop-down menu which input sections to use to drive the subwoofer in the audio system. The subwoofer channel /s can be driven either by the input signal coming from the Front line, or by the input signal coming from the Rear line or by the one coming from the mix of Front+Rear lines. – (3) F + R + SUB L/R: controls Front stereo + Rear stereo + SUB stereo; – (4) F + R + SUB: controls Front stereo + Rear stereo + SUB mono; – (5) F + R + C + SUB: controls Front stereo + Rear stereo + Center + Sub; – (6) F + AUX : controls Front stereo + AUX stereo; – (7) 2 WAY F + AUX: controls a 2 way active Front stereo + AUX stereo; – (8) 2 WAY F + SUB L/R: controls a 2 way active Front stereo + SUB stereo; – (9) 2 WAY F + SUB L/R: controls a 2 way active Front stereo + SUB mono
(1) F + R + AUX
(2) 2 WAY F + R
(3) F + R + SUB L/R
(4) F + R + SUB
(5) F + R + C + SUB
(6) F + AUX
(7) 2 WAY F + AUX
(8) 2 WAY F + SUB L/R
(9) 2 WAY F + SUB
AP4.9 bit will use these names to reconstruct a full band signal coming from
an OEM source with a dedicated multichannel amplifier and to assign the
corresponding signal to the respective output.
Press BACK to return to the previous step. Press NEXT to continue with the
configuration. Press CANCEL to exit the procedure.

6. Input Level Setup. – Play track 1 from the CD provided with AP4.9 bit.
Remark: if the head unit used is not equipped with a CD player, and only
features a USB input, follow the instructions below. 1) Copy the tracks in Wav
format from the CD to the USB storage device. 2) Copy the tracks in mp3 format
from the folder in the setup CD to the USB storage device, in case the first
player is not suitable to reproduce Wav formats.
– Set all tone controls to zero (flat). – Set balance and fader to center. –
Adjust the head unit volume to the maximum undistorted output level. – If the
head unit provides an adjustable equalizer, make sure that the controls are
set to zero (flat).
Select: – 0dB Reference: setup related to the use of music tracks
recorded at 0dB. – Musical setup: for the use of music tracks recorded at a
level lower than 0dB (-3dB ÷ -6dB).
Press BACK to return to the previous step. Press GO to continue with the
configuration. Press CANCEL to exit the procedure. Press SKIP to skip the
level calibration procedure
The input level calibration procedure is a delicate operation and must be
performed very carefully. If not performed correctly, it can nullify the final
sound results.
WARNING: The head unit level must be adjusted to the maximum undistorted
level. If the initial head unit distortion level can not be determined, adjust
the volume to approximately 80% of its maximum. If the head unit output level
is set too low, the device may produce ground noise (hissing sound) when
playing music tracks. This is due to the low signal / noise ratio provided by
the head unit to the AP4.9 bit input. If you experience this problem, after
calibrating the amplifiers sensitivity levels, increase the head unit volume
and repeat the AP4.9 bit calibration procedure as detailed in point 9 of this
paragraph
WARNING: Some factory head units require a low load impedance to be able to
activate the outputs (usually the Rear section). If you cannot adjust the
input signal level during the calibration procedure, it may be necessary to
connect the ASP module in parallel to the input cables for the channels with
the error (see sec. 4.3)
The check for whether or not the ASP module is needed on AP4.9 bit can be
performed using the bit Tune SPEAKER SIMULATOR tool (see sec. 8.1 bit Tune
Advanced Manual).

7. De-equalization. De-equalization of the OEM source, operation not required and not necessary if using low level inputs (Pre out). During the high level input configuration procedure, this function can be used to maximize use of the OEM head units, even if they were equalized to adapt best to the acoustics of the car they are installed in. The de-equalization procedure performs an analysis of the electrical frequency response coming from the various channels on the OEM head unit and automatically applies an equalization opposite to the original one, generating a linear signal that is much more suitable to driving high quality audio systems. Regardless of the input channels used, the de- equalization will be performed by functional groups.
E.g.: Even if using Front Left Full and Front Right Full as inputs, the
software will also perform the de-equalization on the Rear, Center and
Subwoofer since the processor must use the signals identified as Front to also
control any possible Rear, Center and Subwoofer outputs.
If you decide to perform this procedure, follow the instructions below: –
Insert the supplied Setup CD if the source used is an audio CD player; – Play
track 2 (press Play); – Set all of the tone controls to zero (0). – Set the
balance and fader to the center (0). – Don’t change the adjusted volume
previously set through the automatic input level calibration;
Press BACK to return to the previous step. Press GO to continue with the
configuration. Press SKIP to abandon the procedure. Press CANCEL to exit the
program.
The software uses a progress bar and specific messages to show how the
procedure is being executed. At the end of the procedure, the window will show
the equalization curves for the head unit.
Press BACK to return to the previous step. Press NEXT to continue with the
configuration. Press CANCEL to exit the program.

9. Speaker Connection Setup. The speakers present in the system can be
activated by simply clicking on them. The software assumes that if the Left
tweeter, midrange or woofer are selected, the Right ones are also activated.
Once the software is started, this choice will affect the crossover type and
frequencies with Default settings. If passive crossover filters are not used,
each speaker corresponds to an output channel.
Selection of passive crossovers for groups of speakers The presence of passive
crossovers managing functional speaker groups can be indicated. E.g.: If the
audio system features passive crossovers, the software will ask you to set
them by clicking on , otherwise press NEXT. A 2 or 3 way passive crossover
occupies a single output channel.
If the addition of crossovers and/or speakers exceeds 4 channels for an AP4.9
bit or 9 channels for an AP4.9 bit + AP4 D + AP1 D, the software will not
allow you to proceed to the next step. Double-check the crossover
configuration or the speaker setup through the BACK button.

7. Options: By clicking on this item, a drop-down menu appears with the
entries shown in the image:
Signals: Lets you set how AP4.9 bit is turned on through:
· Turn ON by SPEAKER DC (ART): When Enabled is selected, AP4.9 bit can be turned on through the amplified output (BTL) of a source connected to the inputs FL-FR-RL-RR. This function can be disabled by selecting Disabled.
· Turning ON by SIGNAL PRESENCE (AST): When Enabled is selected, AP4.9 bit can be turned on through the presence of a signal from a source connected to the inputs FL-FR-RL-RR, IN1-IN2 (AUX). The stand-by time (energy saver) for the device when there is no signal can be set through the function TIMES -> SLEEP time out for analog input (see next point). The shut down time for the device when there is no signal is set to 30 mins. This function can be disabled by selecting Disabled.
· Input selector: Lets you specialize the “OPTICAL SEL” terminal for automatic selection of the OPTICAL or AUX input. It is also possible to specialize this terminal to turn on the product by clicking on “Enabled”. If you choose to use the “OPTICAL SEL” terminal, it will be active by bringing it to + 12 V.
Times:
Lets you change the settings for the times to turn AP4.9 bit on and off. ·
Remote OUT delay (sec): This is the delay between disabling of
the REMOTE OUT signal to the amplifiers and turning off AP4.9 bit. It is not
usually necessary to change this parameter but it may be useful to decrease it
whenever there are amplifiers that produce a turn off “Bump”.
· MUTE release delay (sec): This is the delay between turning on the device and the activation of the output audio. Each amplifier has a turn on phase, its own delay before being operational. Setting Startup Time to a value equal to or greater than the longest delay will provide synchronized audio startup for the whole system.
· SLEEP timeout for analog input (min): it sets the amplifier’s stand-by time when there is no audio signal. The stand-by time (energy saver) can be set from 1 min minimum to 20 mins maximum. Normal operation is resumed when the audio signal is present. This function is set on 20 minutes by default and can be enabled by selecting the desired amount of minutes. The SLEEP timeout for analog input function allows to save power and provides the ability for the product to work at lower temperatures.
Remark: we recommend that the shortest possible activation time is selected in case of hybrid or electric propulsion cars; it won’t affect the product normal operation.
· Wake delay from sleep (sec): It sets the amplifier resume delay from energy saver status. The delay time can be adjusted from a minimum of 0 sec. to a maximum of 5 secs. This function is set by default at 0 secs (disabled).
Remark: some factory (OEM) head units are provided with a control signal lasting approx. 2 secs during the turn-on phase to check if loudspeakers are in the system (see section 4.3). If the head unit is turned off while the car is being used, the AP4.9 bit, if turned on through ART, will keep working to let the security alerts, phone alerts, navigation system alerts etc. be reproduced . When the head unit is turned on again, the speaker presence control alerts may be reproduced. To avoid this happens, you can set the Wake delay from sleep (sec) duration at a value slightly higher than the duration of the speaker presence control alerts.
WARNING: If the car is equipped with security alerts, phone alerts, navigation
system alerts, …etc., if you set a too long Wake
delay from sleep (sec), reproduction of the first part of the mentioned
signals might be missed.

Power Absorption: By enabling this box you can limit the power absorbed by
AP4.9 bit. If AP4.9 bit is powered through pre-existing vehicle wiring, there
may be a heavy voltage drop at the top of the power supply terminals on the
device. This could happen because the cross-section of the pre-existing cables
is too small. The voltage drops are proportional to the musical power peaks at
high volumes and could generate distortions or even temporary shut down of
AP4.9 bit. If this situation occurs, check the “ENABLED” box and choose the
highest current value, in order to eliminate the problem previously described.
WARNING: The current limitation allows power peaks, intervening only when they
are very frequent and prolonged.
It temporarily reduces the maximum volume of AP4.9 bit.

7.3.11 SET DISTANCE AND DELAY 11
This setting is based on an automatic system that calculates the time needed
for the sound to get from the speaker to the listener’s ear.
Preliminary remarks Sound moves through the air at a speed of 343 m/sec (1.125
ft/sec.) at a temperature of 20° C (68° F). If you know the distance from the
sound emission point, you can then calculate the time the sound takes to get
to the listener’s ear. If you set the distances of the different speakers,
AP4.9 bit will automatically change them into time (ms – milliseconds). It
does not assign a delay (0.0 ms) to the farthest speaker (usually the
Subwoofer) and progressively growing delays as much as the other speakers get
closer to the listening point, in order for all the emission points to reach
the listening point at the same time.
SET DISTANCE Lets you set the distance between the speaker and the listening
point. Choose cm (centimeters) or in (inches). The “Set Distance” boxes can be
set using the cursors.
DELAY ms/default Displays the time in ms (milliseconds) calculated according
to the distance.
DELAY ms/fine set AP4.9 bit time delay calculation system also lets you
perform manual fine tuning.
44
USER’S MANUAL
AP4.9 bit / 7
Preliminary remarks Fine set and Phase delay Delay assignment according to distance calculation is theoretical. Small variations must be applied due to small errors in distance measurement, back-wave reflections inside the car and, primarily, the speaker phase problem. Two speakers reproducing two frequency areas that are close to each other (e.g.: Woofer and Midrange) will simultaneously reproduce the same frequencies in their crossing area, at a attenuated level. Due to the different nature of the speakers, they will have a phase difference that, for a short frequency interval, acts as a time delay. By using “fine set”, you can partly correct these Phase Delay problems.
By using the “fine set” button, you can change the automatically set delay
time. The delay is increased (+x.xx) or decreased (-x.xx) by the delay value
shown in the window “Delay/default” and does not change the value shown, which
is the one that is automatically assigned. Assigning a positive value (+x.xx)
using “fine delay” means increasing the delay for that speaker and thus moving
it farther away from the listening point. Likewise, assigning a negative value
(-x.xx) means decreasing the speaker delay and thus moving it closer to the
listening point.
In order for you to see how much “Fine Set” has been manually changed, both
delay values are shown. To see the resulting delay, physically applied to the
output, you have to add the values shown in the “Delay / Default” and “Delay /
Fine Set” boxes. A negative value (decreasing the delay) can not be assigned
to the farthest speaker; it can only be assigned to the other speakers as they
are all already delayed compared to the farthest one. If you attempt to give
the farthest speaker a negative value, a warning message will appear (Fig. 1).
When using “fine set” “fds” will appear in green on the corresponding channel
on the “Channel Map” (Fig. 2)
(Fig.1) (Fig.2)
Example of setting the time delay (Fig. 3):
1. Choose the system listening point. To identify the listening point, choose
an ideal spot in the center of the listener’s head (driver or passenger). For
the front center and rear center, choose a point between the two listeners.
2. Measure the distance in a straight line from each speaker or group of
speakers compared to the listening point. For each speaker, choose the center
of the mobile membrane as the emission point. For groups of speakers, choose a
point between them. It will then be possible to fine tune it using the Fine
Set function.
3. On the Channel Map, select the channel related to the speaker under
examination and enter the respective distance in the Set Distance box in the
Filter Settings menu.
4. Repeat step 3 for each channel.

5. Once the time delay settings are complete, start the musical reproduction
and use the Fine Set box, moving the values up or down (except for the
subwoofer since it is the farthest speaker) to fine tune the system for
optimal sound. We recommend listening to various types of music (percussion,
melodic, etc.) for better evaluation of the coherence (spatial stability) of
the different musical instruments.
6. Once the time alignment procedure is complete, you can work on the output
equalizer (see sec. 7.3.12) to optimize the system response based on the level
alignment of the various frequencies.
Remark: Measurements for the above operations can also be taken using a
spectrum analyzer with a suitable microphone. The results must be evaluated
and optimized through listening tests.
WARNING: If, once you have set the distances for the “driver”
listening point, you click on the “passenger” listening point, AP4.9 bit won’t
re-calculate the delays for the new reference point because the buttons
available in the SELECT CHANNEL diagram are merely descriptive. Their only
purpose is to remind you that you have set the delays for that listening
point!

7.3.12 PARAMETRIC EQUALIZER 12
The AP4.9 bit software provides an equalizer, that can be managed from
a maximum of 10 graphic control points which automatically place a
maximum of 10 parametric equalization points. The quantity of graphic
1
control points used doesn’t match the parametric poles quantity, which
is determined by the adapting software.
The equalizer works according to the functional groups and so we have the
following factory configuration:
– one equalizer for the Front Tweeter. – one equalizer for the Front Mid – one
equalizer for the Front Woofer. – one equalizer for the Rear.
To be able to change the parameters for the equalizer in order to set
an equalization curve, just choose the channel to equalize from the

USER’S MANUAL
ACCESSORIES
10.1 ASP – AUTOMATIC SPEAKER PRESENCE ASP is indispensable when installing
AP4.9 bit with some OEM sources requiring, only at the initial turn-on
instant, a resistive load impedance at the outputs to detect the speakers’
presence. In case there is no load, the source disables the outputs, usually
only for the Rear section. Therefore, if during the calibration process you
cannot adjust the input signal level due to lack of signal on some or all of
the AP4.9 bit inputs, while installing the ASP module, when you turn on the
AP4.9 bit a temporary load will be simulated; afterwards that load will
automatically get disabled, fixing the issue. Thanks to ASP, there is no need
to mount fixed power resistors at the source outputs; the resistors would
produce heat and, in addition to that, would make the source heat up
unnecessarily.
10.2 ACP 2 – 2 RCA ADAPTER CABLE It is a kit made up of wiring INPUTS AP4.9
bit with RCA connectors for the IN1 and IN2 inputs and a 3.5 mm RCA/Jack
adapter. This wiring manages the signals coming from pre-amplified auxiliary
sources (AUX) through the RCA inputs or portable auxiliary sources using the
3.5 mm RCA/Jack adapter.
10.3 ACP 6 – 6 RCA ADAPTER CABLE It is a kit made up of wiring INPUTS AP4.9
bit with RCA terminations for the FL,FR,RL,RR,IN1 and IN2 inputs and a 3.5 mm

10.11 SFC – SAMPLING FREQUENCY CONVERTER
SFC is a digital audio signal adaptor (SPDIF) to place between two devices
with digital input/output. The main purpose of this adaptor is to solve issues
related to digital interfacing of the two devices such as: 1. Digital head
unit with higher sampling frequency (96/192 kHz) while the
receiver can’t handle frequencies higher than 96 kHz. 2. The
receiver/transmitter does not feature an optical or electric coaxial
input/output: the SFC can be used to recreate the missing connection. 3.
Malfunctioning or anomalous noises when the head unit is set to “Pause”.
The issue is caused by the fact that while being paused some head units strip
away the digital signal carrier wave; SFC constantly provides the carrier wave
to the receiver. 4. When “Play” is selected on the head unit and the music
program is starter or during normal functioning intermittent noises can be
heard even at low volume. This phenomenon is due to poor quality or
insufficient level of the digital signal; SFC can recover the signal
eliminating the issue.
Description SFC is a sampling frequency converter; it converts the digital
signal, inputting an S/PDIF digital signal with from 32 kHz to 192 kHz
sampling frequency and outputting an S/PDIF digital signal with 48 kHz
sampling frequency. SFC does not alter the information travelling along the
signal, it can not handle AC3® or Dolby Surround® encoded signals but just
stereo PCM ones and does not convert the digital signal into analog. SFC
features two inputs: one coaxial electrical (75 ) and another optical
(TOSLINK). You have to select which input will be used through the INPUT MODE
switch. When the ERROR LED lights up, it indicates either that the input
signal is not stereo PCM or that the signal is instable; in that case, the SFC
goes into “Mute” status not to damage the devices connected to its outputs.
SFC features two outputs: one coaxial electrical (75 ) and another optical
(TOSLINK). Both the outputs are active.
