To bit One HD είναι ένας πολυλειτουργικός ψηφιακός επεξεργαστής αναλογικών
εισόδων που μπορεί να μεταμορφώσει μια συνηθισμένη εργοστασιακή πηγή αλλά και
μια AFTER MARKET πηγή ήχου σε ένα σύστημα υψηλης απόδοσης. Η ρύθμιση γίνεται
μέσω ενός ειδικού λογισμικού.
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.
Thanks to the Analog
Devices DSP (ADSP-21489), 32 bit floating-point Sharc series (450 MHz clock),
bit One HD Virtuoso makes the most of Hi-Res audio files achieving studio
master quality in your car.
bit One HD is 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 ports, preserving all the
information of the Hi-Res audio file reproduced.
A dedicated FIR firmware 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 allows
the selection of 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.
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.
13
analog and/or digital output channels ensure a wide 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.
