Audison
bit One.1
Digital Signal Processor
Overview
Despite its compact size, the bit One 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.
Audio DSP and Converters
- 32-BIT floating point Analog Devices Sharc (Clock speed: 266MHz)
- Digital Signal Processing chip and Wolfson A/D D/A converters working in PCM at 48kHz with 24 Bit resolution.
Tuning Functions
- Heard in real-time due to processing speed.
Audio Inputs
- 8 independent high-level channels (with automatic summing capability) or 6 independent analog 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 or navigation systems.
Audio Outputs
- 8 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 Link provided amplifiers
Digital Control System
- 1 USB /B (2.0) connector for PC connection
- 2 AC Link control bus connectors for DRC and AC Link amplifiers
Configuration
Guided procedure that, thanks to a wide range of set names, provides the ability to assign each component to the bit One connections and automatically coordinate their functioning.
Turn-on Controls
- ART 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 Volume
- Input 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 Equalizer
- System automatically self-adjusts through an equalization between low and high listening levels that can be set by the user and controlled by the DRC.
De-equalization and calibration
- Automatic de-equalization of signal fed into the high-level inputs (with supplied Test CD or DVD) and levels calibration.
Equalizers
- One 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 Filter
- Filter 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 Reconstruction
- It can reconstruct a stereo signal from a multi-channel signal. In addition it can reconstruct a centre channel and subwoofer channels from a stereo input alone.
Time Alignment
- Guided procedure for the speaker distance data entry with an automated calculation of proper delay times for each channel for accurate time alignment set-up.
- System also provides for manual fine tuning of delay (0 ÷ 22 ms max).
- Auto Restart
- Automatic turn Off/On, if the DSP locks up.
Control
- DRC Master Volume control
- Subwoofer Volume control
- Balance control
- Fader control
- Input Selection
- Memory Selection
- Dynamic Equalizer On/Off
- Adjustable Display Brightness
- Access to digital features of Audison TH amps if connected
Memory
- 4 presets separately managed and recalled by the DRC Remote Control
Software
- Windows (Win 2000, XP, Vista, 7) based software with “Standard” and “Expert” operating modes
Screen Resolution
- 1024 x 768 px min.
