Features & Specifications



Audison bit Ten Signal Interface Processor

The Audison bit Ten is a digital signal processor that is required to get the most out of your automotive audio system’s acoustic performance. A 32-bit DSP processor and 24-bit AD and DA converters are included. It can connect to any manufacturer system, including those in vehicles with an integrated audio processor, because the de-equalization function ensures that the bit Ten returns a linear signal. It has seven signal inputs: four Hi-Level, one Aux Stereo, and one Phone, as well as five PRE OUT analogue outputs. A 31-band equalisation is offered on each output channel. A 66-frequency electronic crossover, BUTTERWORTH or LINKWITZ filters with 6-24 dB slopes, and a digital time delay line are also included. Through a remote control device called DRC, the user can make settings that allow him or her to interact with the bit Ten.

Audio DSP and converters

32 bit Cirrus Logic (Clock speed: 147 MHz) Digital Signal Processing chip and A/D D/A converters working in PCM at 48 kHz with 24 bit resolution. The processor speed allows the user to hear and verify in real time the changes applied during the tuning.

Audio Inputs

4 independent high-level channels with automatic summing capability and USS (Universal Speakers Simulator), the technology that allows bit processors to work with headunits featuring the “speaker load detection” circuit; 1 analog low-level stereo auxiliary input; 1 high-level momentary audio interrupt input (with priority) on Phone Mute cable (settable through PC).

Audio Outputs

5 independent analog PRE channels featuring adjustable level.

Control Connections

1 USB /B (2.0) connector for PC connection; 1 AC Link control bus connectors for DRC; 1 input for external Mute (settable through PC).


Guided procedure that, thanks to a wide range of set names, provides the ability to assign each component to the Audison bit Ten connections and automatically coordinate their functioning.

Turn-on Controls

ART, Automatic Remote Turn on/off, selectable from Hi-Level Front L. The ART can be enabled through an external switch; Through the Remote IN; Through the car ignition key with memory function; Through the DRC (optional); Automatically through the hands-free phone kit.

In/Out Volume

Input sensitivity manual adjustable for the Master Hi-Level inputs (with supplied Test CD); Manual input sensitivity adjustment for auxiliary inputs; Independent level control for each output channel for system fine tuning (-40 ÷ 0 dB).


Automatic de-equalization of signal fed into the high-level inputs (with supplied Test CD) if necessary. It can also be performed without the PC.


31-band graphic equalizer (1/3 Oct.; ±12 dB) for each output channels.

Crossover Filter

Filter typology: selectable; Hi-pass, Lo-pass, Full Range, Band pass with independent selectable cut-off slope. Cut-off frequency: 70 steps available from 20 Hz to 20k Hz; Cut-off slope: selecable; 6 to 24 dB/Oct.; Selectable alignment: Linkwitz or Butterworth; Mute: selectable for each output (On/Off); Phase: selectable for each output (0°/180°);

Signal channels reconstruction

It can reconstruct a stereo output signal from a multi-channel input signal. In addition it can reconstruct rear, centre and subwoofer output channels from a stereo input.

Time Alignment

Guided procedure for the speaker distance data entry with an automated calculation (distance to time) for each channel for accurate delay times. System also provides for manual fine tuning of delay (0.02 ms fine set).

DRC (optional)

Master Volume, Subwoofer Volume, Balance and Fader controls, Input selection, Memory selection, Adjustable display brightness.


2 presets separately managed and recalled by the DRC (optional).

bit Ten software

Windows (XP, 7 and Vista) based software with “Standard” and “Expert” operating modes; Screen resolution: 1024 x 600 px min.
