Filters
Twelve independent digital notch filters per channel which can be controlled automatically or parametrically from 20 Hz to 20 KHz
High pass filter with cutoff frequency, user-controllable in 1/3-octave intervals between 20 Hz and 1 KHz, 12dB/octave roll-off
Low pass filter with cutoff frequency, user-controllable in 1/6-octave intervals between 3kHz and 20 kHz, 12 dB/octave roll-off
Parametric filter depth: user-controllable in 1 dB steps from +12 dB to -84 dB (parametric mode), 3 dB steps from 0 dB to -80 dB (FBX mode)
Parametric filter width: user-controllable from 1.00 octave to .01 octave FBX filter width: user-controllable from 1.00 octave to .05 octave
Resolution: 1 Hz from 20 Hz to 20 KHz in FBX mode; 1Hz from 20 Hz to 20 KHz in parametric mode
