13-CHANNELS HI-RESOLUTION DIGITAL SIGNAL PROCESSOR

Thanks to the Analog Devices DSP (ADSP-21489), 32 bit floating-point Sharc series (450 MHz clock), bit One HD makes the most of Hi-Res audio files achieving studio master quality in your car. bit One HD is the only processor able to develop an Audison Full DA HD chain, providing pure digital signal tranfer: the digital audio signal comes through one of the two optical digital inputs (TOSLINK up to 24 bit/192 kHz), is processed by the DSP at 24 bit/96 kHz and is sent to Audison amplifiers through two AD link port, preserving all the information of the Hi-Res audio file reproduced.

A dedicated software release enables the user to process up to 9 digital channels with crossover FIR filters.Through this type of sound processing, much more demanding in terms of calculation resources, a leading-edge in-car listening experience is achieved.

Three equalizers based on two different types of digital filters (FIR and IIR) manage the frequency response: 5 poles input equalization (MASTER and AUX) FIR type, to flatten the curve based on the input selected; IIR 11 poles output equalizer, to adapt the frequency response in the car compartment; 5 poles main equalization, FIR type, to “shape” the sound of the entire system according to the user’s personal music preferences.

When bit One HD is connected to an OEM head unit, a guided configuration routine automatically synchronizes the input audio channels, which are often time-delayed from the OEM source or amplifier, prior to the signals summing.

A De-equalization of the OEM system frequency response is then performed, featuring linear-phase FIR filters, to obtain an unparalleled reconstruction of the original signal without altering the phase response.

The RVA (Remote Volume Aux) function allow to select an auxiliary source (like the Audison bit Play HD) and adjust its volume via the OEM Head Unit.

The system setup is graphically managed and all the tuning features can be accessed intuitively, according to specific criteria required by the car audio industry.

bit One HD features 8 memories for the pre-sets of the Windows-based (10, 8, 7 edition) PC software.

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

Connecting the bit One HD to the Audison bit Tune through an automatic procedure, all the processor’s basic audio parameters can be optimized (time alignment, equalization and output levels) ensuring an excellent acoustic result.


Accessories
  • DRC MP – Digital Remote Control Multimedia Play INCLUDEDThe 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.
