Audison bit one is a high-performance audio processor that offers a wide range of features to enhance your car's sound system. It has eight inputs and eight outputs, allowing you to connect various audio sources and amplifiers. With its advanced DSP (Digital Signal Processing) technology, you can fine-tune the sound to your liking, adjusting parameters like equalization, time alignment, and crossover frequencies. The bit one also features a built-in DRC (Dynamic Range Compressor) that helps to optimize the sound quality at different volume levels.

Turning on/

Switching off

We have some problems with the Bit One turning on/switching off.

As indicated in the manual, Bit One could be activated or disactivated

pressing (for a few seconds) the DRC knob. Once the product is

switched off, if you press the DRC knob you can't turn it on again by

means of the DRC. To turn on the unit again by means of the DRC, it is

necessary to disconnect KEY MEM and KEY ON-OFF.

The DRC must be connected to the Bit One by means of the AC Link 1 (DRC) socket and not by means of the AC Link 2 (AMPS)

socket. Furthermore the KEY MEM and KEY SWITCH ON OFF must not be used at the same time and not even with the function

REMOTE IN

Loud "POP" sound when turning on/switching off The problem could be present on some pieces with the first software versions. In this case it is necessary to proceed with the

updating of the Bit One PC firmware and software, available on the web site: http://update.audison.eu

Using the remote input and output you can hear a loud noise (bump) in

the speakers switching off the source

To not hear the bump during the switching off of the source, the amplifiers must be switched off before the Bit One. The correct

sequence is:

1) The source is switched off disactivating the REM OUT output, that is connected with the BIT ONE REM IN.

2) The Bit One starts its switching off sequence disactivating its REM OUT. This makes the amplifier silent and it switches it off.

3) After 2 seconds the Bit One is switched off.

configuration Failing or mistake in the parameters finalization If during the Bit One regulation by means of the PC, the Bit One is switched off or turned on, the PC USB connection looses

sychronisim. If the Bit One switches off during the connection process with the PC it is necessary to disconnect from the PC

program and relaunch it to restore the comunication synchronism.

The Bit One doesn't work correctly once it is switched off and turned on

again.

If during the Bit One programming phase by means of the PC the product doesn't answer the controls, it is necessary to switch off

the Bit One switching off the source or the DRC. If, after this action, you can't switch off the Bit One it is necessary to disconnect

the power source and then reconnect it. Once the Bit One is switched off it is necessary to turn it on again and then redefine the

synchronism disconnecting and reconnecting the management program by means of the PC

Acting on the Master Volume and on the Subwoofer Level there is no

volume variation

Probably setting the I/O wizard configuration, some "set AC-LINK provided amplifier" flags have been set on the outputs. In this

way the Bit One analogic outputs volume always remain 0dB because the volume adjustment is committed to the amplifiers with

AC-LINK that the software considers connected after the processor once set the flag.

To restore the situation it is necessary to redo the setting procedure being careful that the "set AC-LINK provided amplifier" flags

aren't selected.

After selecting MUTE in the "DSP SETTING" CHANNEL MAP, if the

"EXT. SOURCE EQ" is selected, MUTE automatically disactivates and

the sound comes out.

MUTE is still selected, both in the CHANNEL MAP and in the "OUTPUT

LEVEL", but the sound continues to be present.

When MUTE is re-activated after disactivating it, the silence condition

operates correctly.

The problem can be temporarily over come disactivating and re-activating MUTE. The problem can be solved updating the

software and firmware available on the web site http://update.audison.eu . The modification is present from version 1.4 of the PC

management software.

Bii One has been correctly installed and configured by means of the I/O

configuration wizard and then disconnected from the PC and switched

off. After turning on again the Bit One, it doesn't work

Be careful: to not loose the configuration work done it is necessary to "finalize" it on the Bit One by means of the function "finalize

to Bit One" from the PC software File menu

FREQUENT ASKED QUESTIONS

USB connection Anomalies when the USB cable is connected

Some portable PCs powered by means of their external power supply create a strong tension difference between the portable PC

USB ground and the Bit One USB ground: this could create temporary anomalies in the digital section of the Bit One. It is

necessary to make the portable PC work with its battery, keeping it disconnected from the network power supply at least when the

portable PC is connected to the Bit One by means of the USB. Once the connection is stable it is possible to connect the portable

PC by means of the power supply without creating problems.

DRC Difficulty in the passage between the DRC input selection screens. The

system blocks The problem could be present on some pieces with the first software versions. In this case it is necessary to proceed with the

updating of the Bit One PC firmware and software, available on the web site: http://update.audison.eu

functioning The unit presents noise from the cd transporter, noise between the

tracks and when you are in the Bit One Table of Contents The problem could be present on some pieces with the first software versions. In this case it is necessary to proceed with the

updating of the Bit One PC firmware and software, available on the web site: http://update.audison.eu

Problems with the reading of the input levels: the message "input too

low" appears The problem could be present on some pieces with the first software versions. In this case it is necessary to proceed with the

updating of the Bit One PC firmware and software, available on the web site: http://update.audison.eu

Sometimes the DRC switches off (the Bit One Audison logo remains

turned on). To turn it on again it is necessary to take off and put on the

power plug.

What indicated could happen with the first Bit One and could be caused by the optical digital input or coaxial even if it has been

selected with the unconnected and disactivated source. The problem could be eliminated updating the firmware and the

management software by means of the PCwith the ones you can find in the web site http://update.audison.eu.

Changing the input source, without connected cables and apart from the

source (Aux 1, Aux 2, digital ...),you can hear clamp disturb on the

outputs

The problem is due to Bit One muting and could be solved updating the firmware and the management software by means of the

PC, available on the web site http://update.audison.eu.

During the functioning phase it is possible to hear a light sound

distorsion. You can hear random noises when the Bit One elaborates a

wide spectrum signal with deep low bass: as the tails in high

frequency that come after the low frequency signal. This noise level is

very low but present apart from the type of speaker used and even

using a high pass filter. The noises are more present at lower

frequencies and they are present even after the updating of the unit

software.

The problem can be solved updating the firmware and the management software by means of the PC; available on the web site

http://update.audison.eu.

Why are there 3 remote inputs and only 1 remote output? The three Remote IN inputs are requested for the Bit One remote turn on using one or more signal sources. Instead, the Remote

Out function turns on in remote the units or amplifiers connected down to the processor. The three Remore IN inputs are

connected in parallel, so if even one source is present it is possible to use without exception each of the three inputs.

Using the Bit One in “Filter Linkwitz” mode, when selecting the cutting

slope [dB], you hear a ''puk' sound The problem could be solved updating the firmware and the management software by means of the PC, available on the web site

functioning

When using the Bit One Hi-level input, is it possible to use one filtered

signal (example 4" midrange)? In this case, can Bit One remake the

complete signal (20 hz - 20khz)? On some factory installed systems the

high level signal is filtered digitally from the source (for example in the

band 50-70 hz) and often the Sub channel isn't present. In this case it is

difficult to remake the signal for the Sub.

Bit One can mix the Hi Level filtered outputs that come from an OEM source. For example on a Bit One Hi Level input you can

connect the tweeter output and on another input the woofer output. During the set up phase, in the input configurations, it is

sufficient to indicate Front Tweeter and Front Woofer and automatically the Bit One mixes the two channels as Full Range Front.

This operation is possible even with a 3-way system, of course in this way you occupy 6 channels of the 8 available.

If the car OEM system has a cut Hi Pass for example 70 Hz, Bit One can't reproduce frequencies that don't exist on its input. It is

important to say that if the "de-equalize" function is used, if it is equalized or not, the Bit One internal Flattner permits a

realignment of 6 dB of the response curve. This means that in case the OEM source Hi Pass has 70 Hz - 12 dB/Oct, the Bit One

can bring the Hi Pass crossover frequency to 52.5 Hz. This frequency value permits easier Hi-pass crossover cuttings atr higher

frequrncies that are normally used to cross the section "Front" with the Subwoofer one in Car Audio systems. The function "de-

equalize" can be used even with the PRE (Lo Level) input. In this case, before

starting the "de-equalize", it is necessary to supply the signal on 6 PRE (Lo Level Inputs) inputs, during Bit One set up configuratio

it is necessary to "deceive it" selecting the Hi Level Inputs, avoiding to use channel 7 and 8.

The adjusting window of the volumes presents the indication of 0 - -40

db for channel 1 and 0 - -20 db for the remaining channels The problem can be solved updating the firmware and the management software by means of the PC; available on the web site

http://update.audison.eu.

The Bit One is connected to the digital source (optical or coaxial). The

system is turned on but the source is switched off or turned on for a

long time but not in reproduction: turning on the source or restoring the

reproduction there is no sound

This problem is due to the fact that some sources, during the turning on or restoring of the reproduction after a long time of

inactivity, presents an imperfect start of the digital signal S-PDIF: Bit One can't start the decoding of the signal and there is no

sound, in this case it is sufficient to change the source by means of the DRC and then return to the digital source.

installation In the product I can't find a fuse inserted on the PCB or included for

external connection: furthermore I can't find recommandations on a

recommanded value for an eventual external fuse.

On the first pieces produced, the fuse wasn't included and we were working on the possibility to insert an external fuse. On the

next production lots the fuse has been integrated on the PCB that can be replaced only by the assistance center. If you want to put

an external fuse for more safety the adviced value is 1 A (normal)

Once installed the system, carried out the guided procedure and

configuration, we synchronized the processor and finalized. Once

disconnected the USB cable from the PC we don't have Bit One output

signal.

The problem could be solved updating the firmware and the management software by means of the PC; available on the web site

http://update.audison.eu.

Additional

features use How must the KEY-MEM and KEY ON-OFF be used?

The Memory connection is linked to the turning on of the Bit One turning the vehicle key. It is very similar to the connection "KEY

ON-OFF'' to which it adds a "memory" feature. So, if the Bit One has already been switched off when the user turns off the vehicle

(for example by means of the DRC), the Bit One will not turn on at the next turning on of the vehicle. Instead, if the Bit One is on

when the user stops the vehicle and takes out the key, it willl turn on again when the vehicle will be turned on next time. The

contacts KEY ON-OFF and KEY-MEM exclude one another and they mustn't be used at the same time.
