audison.com BIT ONE HD VIRTUOSO 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.
audison.com 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 specific for audio use, with cellulose dielectric treated with silk fiber 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.
audison.com NEW FUNCTIONS AND IMPROVEMENTS The constant work of the Audison development team has produced the new software / firmware release v.2.0 * in order to: 2. Offer even more powerful signal processing tools to specialists including new types of filters 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 configuration 3.
audison.com 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 filter types and is also designed for remote control via an additional Wi-Fi module. B) Added Pass-through input configuration (MASTER) you can now choose between 2 approaches for the input setup: 2.
audison.com FOCUS ON NEW ROUTING CAPABILITIES PASS-THROUGH VS AUTOMATIC Pass-through is more suitable when OEM systems are heavily altered by audio algorithms to increase the perception of audio quality (referred to by car manufacturers as 3D, surround, spatial, etc.). Thanks to the direct connection between input and output, the pass-through approach allows the configuration of the original audio system to remain unaltered, supporting systems up to 7.
audison.com IMPROVED DE-EQ INTRODUCING PHASE ANALYSIS All specifications subject to change without notice_19.A The SW performs the spectrum analysis and flattens it by doing the magnitude DE-EQ automatically. Additionally, the new SW detect the electric polarity of each input channels and, in case of inverted polarities asks the user whether to correct them automatically or manually. The new SW also allows the correction of its phase domain response when the user enables the “Phase analysis” option flag.
audison.com FIR CROSSOVER FILTERS due to increased distortion and lower tweeter power. With a slope of only 6 dB / Oct., the music signal around the cut-off frequency is simultaneously generated by tweeters and woofers to a considerable extent. Since a tweeter and a woofer have very different electro-acoustic parameters, the sum of the two emissions does not produce clear output signals, which results in less clarity in the reproduction of musical transients.
audison.com EXCEEDING THE LIMITS IMPOSED BY PHASE ROTATIONS Similarly, to crossover filters, graphic and parametric equalizers based on IIR filters alter the signal phase behaviour with significant effects on audio quality. A heavily equalized signal is characterized by an unclear stereo image and lack of transients definition. Audiophiles often classify this feeling as a veil that blurs the musical message and deprives it of the necessary emotion.
audison.com PARAMETRIC EQ In professional audio parametric equalizers have long since replaced the graphic ones for their greater precision of intervention as well as a considerable decrease in phase alterations. In fact, in graphic equalizers, to flatten a response curve, one is almost always forced to use almost all of the 31 intervention points offered, but each band introduces a phase shift that is added to the adjacent one, with the result of creating rotations on the whole spectrum.
audison.com 3. MAIN EQ: it can be used at will to personalize the system overall response curve, customizing it for different musical genres POP / ROCK / CLASSIC and JAZZ or depending on the passengers inside the car, in combination with the setting of time delays, using different memory presets. The user can avail of: i. 4 PEQ (FIR) + 1 PEQ (IIR, up to 100Hz) + 1 high-Shelf (FIR) ii.
audison.com AUDIOPHILE AND OEM INTEGRATION SETUP TOGHETER AT THEIR BEST The bit One HD Virtuoso is provided with advanced features for the integration with OEM infotainment and a purely audiophile vocation.
audison.com AUDISON BIT TUNE AUTO TUNING Audison bit Tune is the auto-calibration system for bit One HD Virtuoso for the setup of basic parameters (time alignment, equalization, levels, etc.), ensuring a correct acoustic result in a very short time. The bit Tune automatic routine also includes the diagnosis of common connection “errors” (channels/phase inversion, no signal from a channel/cable, etc.
audison.com CONNECTIVITY OEM INTEGRATION SPECIAL FUNCTIONS The bit One HD Virtuoso further improves its integration level with OEM head units, 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 an auxiliary source such as a Hi-Res audio player. The functions listed below further enhance the processor’s control capabilities.
audison.com DRC MP - DIGITAL REMOTE CONTROL MULTIMEDIA PLAY The DRC MP supplied with the bit One HD Virtuoso features a reduced size and a total black look with possibility of customizing the RGB light of the volume control as well as the keys. A Joystick has been added to the volume knob, providing the ability to intuitively browse the menu, adjust the display colour and brightness and also control a bit Play HD that may be connected to the processor.
