Audison bit One HD, equipped with latest generation 450 MHz / 32 bit floating point DSP microprocessor, processes sound with 24 bit resolution at 96 kHz sampling frequency, achieving studio master quality in your car. The management software user interface makes the system configuration and calibration processes as user-friendly as possible, according to specific criteria required by the Car Audio industry. Twelve input channels for four different signal typologies (amplified, pre-amplified and TOSLINK optical digital) and six different sources managed through DRC MP remote control (provided), making the bit One HD a unique interface suitable for any need. Thirteen analogue and/or digital output channels ensure vast expandability for any audio system configuration.

DRC MP - Digital Remote Control Multimedia Play INCLUDED

The new Audison DRC MP (Digital Remote Control Multimedia Play) is compatible with all the Audison electronics featuring AC Link bus. Its slim profile along with the holder supplied with it eases the installation in the best position inside the car. Thanks to the new Joystick, “Rubber Touch” finished for best control of the movements along the four direction axes, the 'DRC Settings' menu can be adjusted and navigation is also possible through the 'Navy Command' function if the system features an Audison bit Play HD with video output connected to a monitor.
Audio DSP and converters
Analog Devices DSP (ADSP-21489), 32 bit floating-point Sharc series (450 MHz clock). Cirrus Logic (CS5368 8ch and CS4365 6ch) A/D and D/A
converters (24 bit/192 kHz) providing very high level performance

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)

8 Preset separately managed and recalled from the DRC MP

13 independent low-level analog channels and 2 AD Link outputs (13 independent digital audio channels to be connected through two CAT 5.S LAN
cables for use with AD Link provided amplifiers)

Turn on Controls
ART™, Automatic Remote turn On/Off for high level inputs through the DRC MP

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)

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

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

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
