+ Power (11-15 VDC): connection terminal for AP F8.9 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 soket 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
AP F8.9 bit. After applying power, wait at least 10 seconds before turning the AP F8.9 bit on.

LOGO STATUS.

USER’S MANUAL
AP F8.9 bit is provided with a built-in control that manages its status and protects the circuits and connections
to the speakers. The logo on the AP F8.9 bit top cover will change its status in case of any possible product malfunctions.
A BLUE logo means: AP F8.9 bit is on.
Flashing RED/BLUE logo means: The “UPGRADE MODE” switch on the product is set to “ON” position, or the product Firmware is being updated.
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.
Flashing RED logo means:
- AP F8.9 bit temperature reached 75° C and the thermal protection was triggered. It will start operating again at
around 70° C.
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
2Ω 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. This protection is self-restoring.
- 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. This protection is self-restoring.
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.
4
RED logo means:
- Product internal fault. Please contact an authorized service centre. The product will turn off after 3 minutes.

7. HOW TO SET UP AP F8.9 BIT WITH A PC

7.1 OFFLINE MODE

OFFLINE mode can be used to analyze the software without connecting AP F8.9 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.

USER’S MANUAL

7.2 TARGET MODE

In order to configure the inputs, amplified and pre-amplified power outputs, EQ and time delays for AP F8.9 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 request:
- 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 AP F8.9 bit in BRIDGE configuration, thus increasing the power on the output.

WARNING: during this operation, we recommend disconnecting the power connector from AP F8.9 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 AP F8.9 bit (see sec. 4.2). Before
system, make sure the power outputs are disconnected from AP F8.9 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 AP F8.9 bit and connect the USB cable to the PC. Start AP F8.9 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.

- 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 AP F8.9 bit input. If you experience this problem, after calibrating the amplifiers sensitivity levels, increase the head unit volume and repeat the AP F8.9 bit calibration procedure as detailed in point 9 of this paragraph.
Head units output level instrument check
The maximum output voltage and maximum undistorted level can be measured using the Audison bit Tune SOURCE CHECK tool (see sec. 7.1 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;

AP F8.9 bit features 9 output channels. In this specific step of the procedure you can assign any signal to one of the output channels. E.g.: The 3 way front can be controlled as:
- multi amplified (6 output channels are needed);
- passive midrange + woofer amplified separately
(4 output channels are needed);
- 3 way passive (2 output channels are needed). During the selection, the software will automatically notify that the 9 output channel limit has been respected, the warning message will disappear and the NEXT button will appear. For convenience, if output 1 is assigned to the left Tweeter, the software will automatically assign output 2 to the right Tweeter.

Times: Lets you change the settings for the times to turn AP F8.9 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 AP F8.9 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 AP F8.9 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.

7.3.11 SET DISTANCE AND DELAY

2000 Hz @ 24 dB Oct. Low-pass
2000 Hz @ 6 dB Oct. Low-pass
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, AP F8.9 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.

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
(Fig.1)
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).
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, AP F8.9 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!

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 “Channel Map” menu, positioning the mouse over the point to be set, and shape the curve using the left mouse button (green curve), or with the arrow keys “ ” on the PC keyboard.
Remark: to select the frequency parametric pole in FINE mode, use the PC keyboard keys “ + ” or “ + ”.
In order to vary the “Q” factor of the equalization point selected, just scroll using the mouse wheel featuring this function or using the keys “ ” and “ ” on the PC keyboard.
In order to delete the changes, just put the mouse over the point, select it with the left button and press CANC on the PC keyboard.
The equalizer has specific functions that aid in calibration and make it easier.

The following parameters are listed:
- Fc: parametric pole operating frequency (Fmin 20Hz ÷ Fmax 20KHz).
- G: parametric pole gain (Gmin +12dB ÷ Gmax -12dB).
- Bw: bandwidth of the parametric pole applied (Bwmin 100Hz ÷ Bwmax 4800Hz). To prevent the display of this window just press the ESC key from the PC keyboard.
Remark: In order to clearly display the set equalization curve, you can increase or decrease the vertical axis (dB) and horizontal axis (Hz) by moving the cursors to the side of them. The default is set to +12 dB and 0-20 kHz.

9.1.2 DRC AB

AP F8.9 bit /
9
The DRC AB is the digital interface between the bit processors and the user providing reduced functions compared to the DRC MP. When mounted on the vehicle’s dashboard with an AP F8.9 bit processor, it will enable the following functions:
- select Master or Optical input
- control general volume, subwoofer volume, balance and fader.
- select between 2 memories pre-set by the user for the set up
of equalizer and crossover alignment.

9.2 SPM4 (Stereo Passive Mixer 4Ch)

Stereo passive mixer (unpowered) featuring 4 input channels and 2 output channels, designed for active OEM multi-way systems where each speaker is powered by one specific amplified channel. SPM4 mixes audio through 4 audio transformers specifically developed to achieve very low distortion and highly linear acoustic response. SPM4 provides the ability to mix the midrange/woofer and tweeter channels coming from the amplifier and supply one single mid-high channel. The Ch1(L/R) channels feature two inputs, one features an inverting input compared to Ch2 (L/R) channels; the mixing process often gives better results when one of the two channels undergoes a 180° dephasing. SPM4 is especially recommended to extend the number of inputs of the Audison digital processors or amplifiers with built-in DSP because they feature a De-equalizer (De-Eq). In that case, any possible non-linear acoustic emissions due to the mixing of the pre-existing filtered channels are duly compensated.
