BIT ONE.1

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

• 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 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 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 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.

Bit One software

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