Audio DSP and converters
32 bit Cirrus Logic (Clock speed: 147 MHz) Digital Signal Processing chip and A/D 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 optical digital 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;
1 AD Link output featuring 8 independent digital audio channels through a single CAT 5.S
LAN cable for use with amplifiers featuring AD Link input.
Control Connections
1 USB /B (2.0) connector for PC connection;
1 AC Link control bus connector for DRC;
1 AC Link control bus for use with amplifiers featuring AC Link;
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 D connections and automatically coordinate their functions.
Turn-on Controls
ART, Automatic Remote Turn on/off, selectable from Hi-Level Front L. The ART can be
enabled through an external switch;
Through the Remote IN;
Through vehicle ignition key trigger with memory function;
Through the DRC;
Automatically through the hands-free phone kit momentary interrupt.
In/Out Volume
Manual input sensitivity adjustment 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.; ±12dB) for each analog and digital output channel.
Crossover Filter
Filter typology: Hi-pass, Lo-pass, Full Range or Band-pass with independent
selectable cut-off slope;
Cut-off frequency: 70 steps available from 20 Hz to 20 kHz;
Cut-off slope: 6 to 24 dB/Oct.;
Filter alignment: Linkwitz or Butterworth;
Mute function: 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 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
Master Volume, Subwoofer Volume, Balance and Fader controls, Input selection,
Memory selection, Adjustable display brightness. Access to digital features of amplifiers
featuring AC Link.
Memory
2 presets separately managed and recalled with the DRC.
bit Ten D software
Windows (XP, Vista and 7) based software with “Standard” and “Expert” operating modes;
Screen resolution: 1024 x 600 px min.
