Audison Bit Ten Multi-Function Signal Interface Digital Processor - BITTEN
bit Ten is a multi-function digital processor featuring analog input, capable
of transforming ordinary OEM or after-market system into a high-performance
system.
Provided with a 32 bit, 147 MHz clock speed DSP as well as 24 bit A/D and D/A
converters, bit Ten is controlled by a software especially developed for signal
treatment according to the vehicle acoustic peculiarities. Setting the parameters
of each input single channel, setting the delays according to the listening
position, adjusting crossovers and equalizers for each of the 5 output channels;
all of these operations can be managed by the PC.
During the installation phase, after converting the analog signal into digital,
bit Ten automatically reconstructs a digital full-bandwidth stereo signal; de-equalizes
the frequency response and, if necessary, reconstructs the central and subwoofer
channels.
The user can configure the output mode of each channel relative to the installed
system. It is designed to be connected with the DRC, Digital Remote Control
(optional).
Features:
- Audio DSP and converters: 32 bit Cirrus Logic (Clock speed: 147 MHz)
Digital Signal Processing chip and A/D and converters D/A converters working
in PCM at 48 kHz with 24 bit resolution. The processor speed allows the user
to hear and verify in real time the changes applied during the tuning
- Audio Inputs
- 4 independent high-level channels with automatic summing capability
- 1 analog low-level stereo auxiliary input
- 1 high-level momentary audio interrupt input (with priority) on Phone
Mute cable (settable through PC)
- Audio Outputs: 5 independent analog PRE channels featuring adjustable
level
- Control Connections:
- 1 USB /B (2.0) connector for PC connection Connections
- 1 AC Link control bus connectors for DRC
- 1 input for external Mute (settable through PC)
- Configuration: Guided procedure that, thanks to a wide range of set
names, provides the ability to assign each component to the bit Ten connections
and automatically coordinate their functioning
- Turn-on Controls:
- ART™, Automatic Remote Turn on/off, selectable from Hi-Level Front L.
The ART™ Controls can be enabled through an external switch
- Through the Remote IN
- Through the car ignition key with memory function
- Through the DRC (optional)
- Automatically through the hands-free phone kit
- In/Out Volume: Input sensitivity manual adjustable for the Master
Hi-Level inputs (with supplied Test CD) Manual input sensitivity adjustment
for auxiliary inputs Independent level control for each output channel for
system fine tuning (-40 ÷ 0 dB)
- De-equalization: Automatic de-equalization of signal fed into the
high-level inputs (with supplied Test CD) if necessary. It can also be performed
without the PC
- Equalizers: 31-band graphic equalizer (1/3 Oct.; ±12 dB) for each
output channels
- Crossover Filter:
- Filter typology: selectable; Hi-pass, Lo-pass, Full Range, Band pass
with independent selectable cut-off slope
- Cut-off frequency: 70 steps available from 20 Hz to 20k Hz
- Cut-off slope: selectable; 6 to 24 dB/Oct.
- Selectable alignment: 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 output
signal from a multi-channel input signal. In addition it reconstruction can
reconstruct rear, centre and subwoofer output channels from a stereo input
- Time Alignment: Guided procedure for the speaker distance data entry
with an automated calculation (distance to time) for each channel for accurate
delay times. System also provides for manual fine tuning of delay (0.02 ms
fine set)
- DRC (optional): Master Volume, Subwoofer Volume, Balance and Fader
controls, Input selection, Memory selection, Adjustable display brightness
- Memory: 2 presets separately managed and recalled by the DRC (optional)
- bit Ten Software: Microsoft Windows (XP, 7 and Vista) based software
