8
Frequency response at maximum gain (60dB) = -dB down at 6Hz and -dB down 8kHz
CMRR=8dB (Channel , kHz, maximum gain with + dBu input)
Crosstalk Channel to Channel: with 0dB@kHz input to chA, chB output =0dBrA. With 0dB@0kHz input to chA,
chB output = 8dBrA
Line Input Response
Gain range = -0dB to +0dB in 0dB steps + 0 dB of variable gain
Input Impedance = 0kΩ from 0Hz to 00kHz
Noise at main output with gain at unity (0dB) = -6dBu measured with a Hz/kHz band-pass lter
Signal to noise ratio relative to max headroom (dBu)=0dB
Signal to noise ratio relative to 0dBFS (+dBu) = 8dB
THD at unity gain (0dB) = 0.00% measured with a 0dBu input signal and with a Hz/kHz band-pass lter
Frequency Response at unity gain (0dB) = -0.dB down at 0Hz and -dB down at 00kHz
Instrument Input Response
Gain range = 0dB to 0dB continuously variable
Input Impedance:
High = MΩ
Low = 00kΩ
Noise at minimum gain (+0dB) = -dBu measured with a Hz/kHz band-pass lter
Noise at maximum gain (+0dB) = -6dBu measured with a Hz/kHz band-pass lter
THD at minimum gain (+0dB) = 0.00% measured with a 0dBu input signal and with a Hz/kHz band-pass lter
Frequency Response at 0dB gain with -0dB input = 0Hz-00kHz +/- 0.6dB
Frequency Response at 0dB gain with -0dB input = -.5dB down at 0Hz and 0dB at 00kHz
High Pass Filter
Roll off = 8dB per octave  pole lter
Fixed Frequency 75Hz measured at the dB down point
Meters
Moving coil (MC) meter is factory calibrated to 0VU = +dBu with kHz sinewave. With the VU Cal button pressed, the meter can
be adjusted on the rear panel to allow 0VU to equal +0dBu to +6dBu with the centre detent being equal to +dBu
Peak LED meters calibrated in the detent position for 0dBFS = +dBu, calibration is adjustable on the rear panel to allow 0dBFS
to equal +0dBu to +6dBu
Routing for MC and Peak meter is after the HPF, pre insert send or switched post insert return. Peak is always pre ADC channel ,
which can be fed by external input or Instrument input.
LED levels are as follows when peak calibration is set to center detent on the rear panel. (This is when using the internal ADC).
0 = +dBu
- = +0dBu
-6 = +6dBu
- = +0dBu
-8 = +dBu
- = -0dBu
