Sound processor Audison Bit One v1

Audio DSP and converters

32-BIT floating point Analog Devices Sharc (Clock speed: 266MHz) Digital Signal Processing chip and Wolfson A/D D/A converters working in PCM at 48kHz with 24 Bit resolution. Tuning functions can be heard in real time due to processing speed

Audio Inputs

8 independent high-level channels (with automatic summing capability) or 6 independent
analog low-level channels
2 analog low-level stereo auxiliary inputs
1 optical digital input
1 electric coaxial digital input
1 high-level momentary audio interrupt input (with Mute IN) for use with mobile phone or navigation systems

Audio Outputs

8 independent low-level analog channels featuring adjustable level and 1 AD Link output
(8 independent digital audio channels through a single CAT 5.S LAN cable for use with AD Link provided amplifiers)

Digital Control System

1 USB/B (2.0) connector for PC connection
2 AC Link control bus connectors for DRC and AC Link amplifiers

Configuration

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

Turn-on Controls

ARTTM automatic remote turn on/off circuit.
Through the car ignition key with memory function.
Through the DRC.
Automatically through the hands-free phone kit.

In/Out Volume

Input sensitivity automatically adjusted for the main inputs (with supplied Test CD and DVD)
Manual input sensitivity adjustment for auxiliary inputs
Independent level control for each output channel for system fine tuning (-40 ? 0 dB)

Dynamic Equalizer

System automatically self-adjusts through an equalization between low and high listening levels that can be set by the user and controlled by the DRC

De-equalization and calibration

Automatic de-equalization of signal fed into the high-level inputs (with supplied Test CD or DVD) and levels calibration

Equalizers

One 31-band graphic equalizer (1/3Oct.; ±12dB) for each one of the 4 auxiliary input
One 31-band graphic equalizer (1/3 Oct.; ±12dB) for each one of the 8 output channels

Crossover Filter

Filter typology: Selectable; Hi-pass, Lo-pass, Bandpass, Full Range
Cut-off frequency: 70 steps available from 10Hz to 20kHz
Cut-off slope: Selectable; 6 to 48 dB/Oct.
Alignments: Selectable; 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 signal from a multi-channel signal. In addition it can reconstruct a centre channel and subwoofer channels from a stereo input alone

Time Alignment

Guided procedure for the speaker distance data entry with an automated calculation of proper delay times for each channel for accurate time alignment set-up.
System also provides for manual fine tuning of delay (0?22 ms max)

Auto Restart

Automatic turn Off/On, if the DSP locks up

DRC

Master Volume control, Subwoofer Volume control, Balance control, Fader control, Input selection, Memory selection, Dynamic Equalizer On/Off, Adjustable display brightness, Access to digital features of Audison TH amps if connected

Memory

4 presets separately managed and recalled by the DRC Remote Control
