Audison Bit One HD – high definition signal processor
Audio DSP and converters
Analog Devices DSP, 32 bit floating-point Sharc series (450 MHz clock). Cirrus Logic A/D and D/A converters (24 bit/96 kHz) providing very high level
performance.
Inputs
12 independent high-level channels (signal-summing) or 6 independent analog low-level channels
2 analog low-level stereo auxiliary inputs
2 optical digital inputs (TOSLINK)
Memory
8 Preset separately managed and recalled from the DRC MP
Outputs
13 independent low-level analog channels and 2 AD Link outputs (13 independent digital audio channels to be connected through a single CAT 5.S LAN cable for use with AD Link provided amplifiers)
Turn on Controls
ART™, Automatic Remote turn On/Off for high level inputs through the DRC MP
Configuration
Guided procedure for the calibration and “signal routing” of the input channels to the output channels based on type and number of inputs, loudspeakers and amplifiers, for the system setup to be developed
Signal summing, De-Equalization and Delay compensation
Automatic algorithms dedicated to the reconstruction of a stereo signal from a multi-channel signal and to fine-tune the signal in advanced OEM systems: time delay compensation (De-Ta); sum of multi-amplified and limited bandwidth signals; signal de-equalization (De-Eq)
In/Out Volume
Input sensitivity automatically adjusted for the main inputs (Wizard with CD and DVD Test)
Manual input sensitivity adjustment for auxiliary inputs (SW)
Independent level control for each output channel for system fine-tuning (-40 ÷ 0 dB)
Dynamic Equalizer
Automatic system for the dynamic equalization between low and high listening levels, to be selected by the user via DRC MP
Equalizers
Four 5-poles parametric FIR type equalizers, one for each source
Thirteen 11-poles parametric IIR equalizers, one for each output channel
One 5-poles parametric FIR type main equalizer
Bass Boost
Low frequencies enhancement based on parametric equalizer, bound to the Woofer and Sub sections, to be set up by the user and selectable via DRC MP
Crossover filter
Filter type: selectable; Hi-Pass, Lo-Pass, Band-Pass, Full Range
Cut-off frequency: 70 steps available from 10 ÷ 20 kHz
Cut-off slope: selectable; 6 ÷ 48 dB Oct.
Alignments: selectable; Linkwitz, Butterworth, Bessel
Mute/Solo: selectable for each output (On/Off)
Phase: selectable for each output (0°/180°)
Time alignment
Procedure to set up the time delays on the real distances between the loudspeakers and the listening point (0÷22 ms max). The system also provides
for a manual fine-tuning in steps of 0.01 ms.
Auto restart
Auto restart in case of DSP fault
DRC MP
Control: Master Volume (-60 ÷ 0 dB), Subwoofer Volume (-12 ÷ 0 dB), Balance, Fader; Inputs selection; Management of the pre-sets stored;
Bass Boost function turn on/off;
PC Connection
1 micro USB connector (1.1/2.0/ 3.0 compatible) to connect to the PC
bit One HD software
Windows-based software (32/64 bit): Windows XP, Vista, 7, 8, 8.1, 10 available in “Standard” or “Expert” mode
Minimum resolution: 800 x 600
