5. Specifications
DSP structure
4 channels with completely independent 24 bit / 96 kHz digital audio processing output levels
Output level and master volume
Independent setting of output level for each channel: +12 to - dB (very good resolution with precise 0.5
dB increments from +12 to -20 dB)
Common setting for overall output level (master volume): +10 to -0 dB (precise 0.5 dB increments from -
10 to -20dB)
Delay
For channels 3 and 4
Delay: 0 to 680 ms (0 to 233 meters). Settings: in meters (1-meter increments, calibrated to an acoustic
velocity of 343 m/s, according to a room temperature of 20°C)
Variable graphic equalizer (VariGraph EQ)
48 bands (12 per output)
