OUT

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 Hi­End systems.
This was made possible thanks to innovative functions born with
the new software / rmware development and the upgrade of
some key components in the audio signal path, which are crucial
to reach new heights of listening pleasure.

BIT PLAY HD

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
ampliers equipped with AC / AD link inputs, preserving every
nuance with maximum purity.

AUDIOPHILE COMPONENTS

The use of these high rated components contributes to obtaining more musical
medium-high frequencies and a powerful and fast low range when the analog

outputs of the bit One HD Virtuoso are used.

1. SILMICseries ELNA capacitors specic for audio use, with cellulose dielectric
treated with silk ber to mitigate the mechanical energy that comes from the bit One

HD vibrations, a common condition for in-car use. The result is a superior acoustic
performance.

2. WIMA high performance Metallized Polypropylene lm capacitors featuring
extremely low dissipation factor and dielectric absorption, to ensure extra clean and
dynamic high-frequency reproduction.

3. High-Performance Burr Brown OP Amps OPAx134 SoundPlus ™ series specic for
absolute level audio applications, characterized by very low distortion / noise and
a high response rate without saturation, features that increase the dynamic range
and listening realism.

4. Cirrus-Logic CS4365 6-channel and CS4385 8-channel 24 bit / 192 kHz DA
converters with 114 dB signal-to-noise ratio and the possibility to choose between

two slow / fast digital lter responses to customize the listening experience at best.

NEW FUNCTIONS AND IMPROVEMENTS

The constant work of the Audison development team has
produced the new software / rmware release v.2.0 * in order to:

1. Strengthen the integration with the latest generation OEM
systems and at the same time raise the performance level
of Hi-End systems with a “purist” approach in Full DA HD

conguration

2. Offer even more powerful signal processing tools to

specialistsincludingnewtypesoflters

3. Make the use of PC-Software even more immediate through a
renewed GUI that facilitates the work of specialists

* The SW / FW v.2.0 is compatible with any HW version of the bit
One HD Virtuoso and with any DRC MP.

A) Only one FW to support both FIR and IIR digital networks.

You can choose FIR or IIR version without the need to update the
FW as for the previous release. The SW 2.0 is compatible with
both network lter types and is also designed for remote control
via an additional Wi-Fi module.

B) AddedPass-throughinputconguration(MASTER)

you can now choose between 2 approaches for the input setup:

1. Automatic routing: consists on the traditional Audison I/O
routing approach, applicable to both OEM integration (hi-level)
or After-market (low-level) scenarios, and it is based on signal
summing, signal reconditioning & flattening. With this setup
type, automatic algorithm options named DE-EQ / DE-Phase,

Compensation of TA, Polarity check and Auto Input Switch can be
selected.

2. Pass-through: consists on an alternative I/O routing approach
dedicated to OEM sound systems (hi-level), that is literally based
on “pass-through” the existing OEM infotainment’s output
channels (connected to bit One HD Virtuoso’s speaker level inputs)
to the bit One HD Virtuoso’s outputs. The SW doesn’t perform any
signal summing and front reconditioning or flattening. However,
the factory output channels are analyzed by the SW, that is able
to identify bandwidth and factory TA. All this information is
displayed in the input analysis dashboard, and can be evaluated
and manually compensated by the user, thanks to the new SW
sound tuning capabilities (EQ lters).
