Με την συνεχή έρευνα στον ψηφιακό τομέα, η Audison δημιούργησε
την κορυφαία συσκευή επεξεργασίας ήχου hi-res. Tο bit One HD έχει την δυνατότητα
επεξεργασίας σημάτων ήχου με ανάλυση 96 kHz/ 24-bit, για τη διατήρηση κάθε
απόχρωσης ήχου.
To bit One HD κάνει τα περισσότερα από τα αρχεία ήχου Hi-Res να
επιτυγχάνουν την ποιότητα του στούντιο στο αυτοκίνητό σας. Ο bit One HD είναι ο
μόνος επεξεργαστής που μπορεί να αναπτύξει μια Audison Full DA HD, παρέχοντας
καθαρό ψηφιακό σήμα μετάδοσης: το ψηφιακό σήμα ήχου έρχεται μέσω μιας από τις
δύο οπτικές ψηφιακές εισόδους (TOSLINK έως 24 bit / 192 kHz) το DSP σε 24 bit /
96 kHz και αποστέλλεται στους ενισχυτές Audison μέσω δύο θύρων σύνδεσης AD,
διατηρώντας όλες τις πληροφορίες του αναπαραγωγόμενου αρχείου ήχου Hi-Res

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
SHARK™ 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.
