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 analog and/or digital output channels ensure vast expandability for any audio system configuration.

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 channe;s (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

Ouputs

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-Equalisation 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 sustems: time delay compensation (De-Ta); sum of multi-amplified and limited bandwidth signals, signal de-equalisation (De-Eq)

In/Out Volume

• Input sensitivity automatically adjusted for the main inputs (Wizard with SD 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 Equaliser

Automatic system for the dynamic equalisation between low and high listening levels, to be selected by the user via DRC MP

Equaliser

• Four 5-poles parametric FIR type equalisers, one for each source
• Thirteen 11-poles parametric IIR equalisers, one for each output channel
• One 5-poles parametric FIR type main equaliser

Bass Boost

Low frequencies enhancement based on parametric equaliser, bound to the wooder and sub sections, to be set up by the user and selectable via DRC MP

Crossover Filter

• Filter type L 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 listening point (0÷22 ms max). The system also provides for a manual fine-tuning in steps of 0.01ms.

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 funcction turn on/off

PC Connection
