Audio DSP and converters

32-BIT oating 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 ampliers).

Digital Control System

1 USB /B (2.0) connector for PC connection;
2 AC Link control bus connectors for DRC and AC Link ampliers.

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

ART 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 ne 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 10 Hz to 20 kHz;
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 ne 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.

Bit One software

Windows (Win 2000, XP, Vista, 7) based software with “Standard” and “Expert” operating modes;
Screen resolution: 1024 x 768 px min.
