Description

bit One HD VirtuosoDSP

12 input channels 

13 output channels 

24 bit

96 kHz floating point processing

Just as the virtuous performer holds the absolute mastery of the instrument and the technique connected to it, the bit One HD Virtuoso features unique skills dedicated to the most ambitious OEM Integration projects and excels in the uncompromising Hi-End systems. This was made possible thanks to innovative functions born with the new software/firmware development and the upgrade of some key components in the audio signal path, which are crucial to reach new heights of listening pleasure. bit One HD Virtuoso allows the creation of an Audison Full DA HD (Full Digital Audio HD) system where the audio signal is transmitted digitally from the Hi-Res audio player to the Audison amplifiers equipped with AC / AD link inputs, preserving every nuance with maximum purity.

TECHNOLOGIES

Full DA HD

Pure digital signal transfer with a resolution up to 24 bit / 96 kHz

Hi-Res audio

According to the definition of HiRes audio provided by JAS (Japan Audio Society – jas-audio.or.jp), bit One HD Virtuoso meets 24 bit / 96 kHz native processing requirement.

ANALOG DEVICE SHARC™ DSP

Analog Device SHARC™ series chip with floating point precision, to reach the highest audio quality.

FIR FILTERS

A dedicated firmware release enables the user to process up to 9 digital channels with crossover FIR filters. This sound processing mode, much more demanding in terms of calculation resources, ensures a leadingedge in-car listening experience.

RVA (Remote Volume Aux)

This exclusive technology provides the ability to select an auxiliary source (I.e.: a HI-Res audio player or auxiliary wireless interface connected by digital inputs) and adjust its volume via the OEM Head Unit, offering full support to the management of the car priority signals such as parking sensor alerts, GPS messages, phone and vocal commands whilst music is played through the auxiliary source.

USS technology

USS technology allows bit processors to work with headunits featuring the “speaker load detection” circuit

BIT DRIVE

Auto tuning by Audison bit Tune and communication with bit Drive portal.

DE-EQ

De-equalization function to “flatten” any equalization applied by default by OEM sources.

DE-TIME

Input delay compensation of time-delayed factory outputs prior to signal summing.

DE-PHASE

Compensation of the overall system phase to recreate the original signal, even in case of OEM sound enhancement algorithms.

POLARITY-CHECK

High level inputs polarity check and automatic correction in case of inversion.
