Audison bit BIT ONE HD VIRTUOSO 13-Channel Hi-Res Digital Processor

13-Channel Hi-Res Digital Processor

Despite its compact size, the Audison bit BIT ONE HD VIRTUOSO is equipped with a powerful 266 MHz / 32 bit floating point DSP microprocessor, working in real time on all the functions of the most complete systems. Managed and configured by a simple and intuitive computer software, it is possible to make adjustments to improve the signal through each phase of its path; from input to output.

Eight input channels for four different signal typologies (amplified, pre-amplified, coaxial electric and TOSLINK optical digital) and six different sources managed through a remote control, making the bit One a unique interface suitable for any need.Eight analog and/or digital output channels ensure a wide expandability for any audio system configuration.

Features:

• 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.
