13-Channel Hi-Res Digital Processor Despite its compact size, the Audison bit BIT ONE HD VIRTUOSO is equipped with a powerful 266 MHz / 32 bit floating point DSP microprocessor, working in real time on all the functions of the most complete systems. Managed and configured by a simple and intuitive computer software, it is possible to make adjustments to improve the signal through each phase of its path; from input to output. Eight input channels for four different signal typologies (amplified, pre-amplified, coaxial electric and TOSLINK optical digital) and six different sources managed through a remote control, making the bit One a unique interface suitable for any need.Eight analog and/or digital output channels ensure a wide expandability for any audio system configuration. Features: Audio DSP and converters32-BIT floating point Analog Devices Sharc (Clock speed: 266MHz) Digital Signal Processingchip and Wolfson A/D D/A converters working in PCM at 48kHz with 24 Bit resolution. Tuning functions can be heard in real time due to processing speed. Audio Inputs8 independent high-level channels (with automatic summing capability) or 6 independentanalog low-level channels;2 analog low-level stereo auxiliary inputs;1 optical digital input;1 electric coaxial digital input;1 high-level momentary audio interrupt input (with Mute IN) for use with mobile phone ornavigation systems. Audio Outputs8 independent low-level analog channels featuring adjustable level and 1 AD Link output(8 independent digital audio channels through a single CAT 5.S LAN cable for use with AD Linkprovided amplifiers).Digital Control System1 USB /B (2.0) connector for PC connection;2 AC Link control bus connectors for DRC and AC Link amplifiers. ConfigurationGuided procedure that, thanks to a wide range of set names, provides the ability to assigneach component to the bit One connections and automatically coordinate their functioning. Turn-on ControlsART automatic remote turn on/off circuit;Through the car ignition key with memory function;Through the DRC;Automatically through the hands-free phone kit. In/Out VolumeInput sensitivity automatically adjusted for the main inputs (with supplied Test CD and DVD);Manual input sensitivity adjustment for auxiliary inputs;Independent level control for each output channel for system fine tuning (-40 ÷ 0 dB). Dynamic EqualizerSystem automatically self-adjusts through an equalization between low and high listeninglevels that can be set by the user and controlled by the DRC. De-equalization and calibrationAutomatic de-equalization of signal fed into the high-level inputs (with supplied Test CD orDVD) and levels calibration. EqualizersOne 31-band graphic equalizer (1/3Oct.; ±12dB) for each one of the 4 auxiliary input;One 31-band graphic equalizer (1/3 Oct.; ±12dB) for each one of the 8 output channels. Crossover FilterFilter typology: Selectable; Hi-pass, Lo-pass, Bandpass, Full Range;Cut-off frequency: 70 steps available from 10 Hz to 20 kHz;Cut-off slope: Selectable; 6 to 48 dB/Oct.;Alignments: Selectable; Linkwitz or Butterworth;Mute: Selectable for each output (On/Off);Phase: Selectable for each output (0°/180°). Signal channels reconstructionIt can reconstruct a stereo signal from a multi-channel signal. In addition it can reconstruct acentre channel and subwoofer channels from a stereo input alone. Time AlignmentGuided procedure for the speaker distance data entry with an automated calculation of properdelay times for each channel for accurate time alignment set-up. System also provides formanual fine tuning of delay (0 ÷ 22 ms max).Auto RestartAutomatic turn Off/On, if the DSP locks up.
