TECHNOLOGIES
Pure digital signal transfer with a resolution up to 24 bit / 96 kHz
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™ series chip with floating point precision, to reach the highest audio quality.
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.
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 allows bit processors to work with headunits featuring the “speaker load detection” circuit
Auto tuning by Audison bit Tune and communication with bit Drive portal.
De-equalization function to “flatten” any equalization applied by default by OEM sources.
Input delay compensation of time-delayed factory outputs prior to signal summing.
Compensation of the overall system phase to recreate the original signal, even in case of OEM sound enhancement algorithms.
High level inputs polarity check and automatic correction in case of inversion.
