Audison Bit One

Signal Interface Processor

Despite its compact size, the bit One is equipped with a fast, latest generation 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 vastexpandability for any audio system configuration.

Description

 

  • Inputs
  • 8 independent high-level channels 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
  • Outputs
  • 8 independent low-level analog channels 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)
  • Connections
  • 1 USB /B (2.0) connector for PC connection
  • 2 AC Link control bus connectors for DRC and AC Link amplifiers
  • System
  • Full range stereo or multichannel signal derived through automatic summing of up to eight high level inputs
  • Configuration
  • Guided procedure to assign input channels to selected output channels based on inputs, speaker and amplifier configuration
  • If necessary, Bit One creates a rear, subwoofer and center channel output (mixed L+R) from a single stereo input
  • 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)
  • Equalizer
  • Dynamic equalizer: system self-adjusts between low and high listening levels
  • Automatic de-equalization of signal fed into the high-level inputs
  • (with supplied Test CD and DVD)
  • Four separate 31-band graphic equalizers (1/3 Oct.; ±12dB) for each auxiliary inputs
  • Eight independent 31-band graphic equalizers (1/3 Oct.; ±12dB) for each of the eight 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°)
  • Time Alignment
  • Guided procedure for the inputting of speaker distance 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.
  • DRC
  • Master Volume control, Subwoofer Volume control, Balance control, Fader control, Input selection, Memory selection, Dynamic Equalizer On/Off
  • Memory
  • 4 presets separately managed and recalled from the DRC Remote Control
  • Standard Mode
  • Simplified management of crossover and equalization functions for expedient set-up and use
  • Expert Mode
  • Full management of crossover and equalization functions
  • for full reference grade system tuning
