H8 DSP
DIGITAL INTERFACE PROCESSOR
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 built-in USS technology (Universal Speakers
Simulator) and automatic summing capability.
1 analog low-level stereo auxiliary input.
1 optical digital input.
AUDIO OUTPUTS
8 independent analog PRE channels featuring adjustable level.
CONTROL CONNECTIONS
1 USB /B (2.0) connector for PC connection.
Optical In / Aux Wire control +12V/GND.
Wire control Memory A/B.
1 Connector for DRC HE.
CONFIGURATION
Guided procedure which, thanks to a wide range of default settings, provides the ability
to assign each component to the H8 DSP connections and automatically coordinate their
functions.
TURN-ON CONTROLS
ART™, Automatic Remote Turn on/off, selectable from Hi-Level Front L.
The ART™ function can be enabled through an external switch, the Remote IN, the vehicle
ignition key with memory function, the DRC HE (optional).
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 the high-level inputs signal (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: 68 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 also 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 accurate time delays.
“Fine-tuning” can also be manually applied (0.02 ms fine set).
REMOTE CONTROL
Master Volume, Subwoofer Volume, Balance and Fader controls, Input selection, Memory
selection.
MEMORY
2 presets separately managed and recalled via DRC HE and wire control.
