Engineering Specifications - SABINE Power-Q Operating Information Manual

FBX/Parametric Filters
Twelve independent digital notch filters per channel, controlled
automatically or parametrically from 20 Hz to 20 KHz, each switchable
between FBX fixed filters, FBX dynamic filters and parametric filters
Filter depth: user-controllable in 1dB steps from +12 dB to -84 dB
(parametric mode), 3 dB steps from 0 dB to -80 dB (FBX mode); max.
automatic depth adjustable from -6 to -80dB
Filter width: user-controllable from 9.99 octave to .01 octave
(parametric), 1.0 to .01 octave (FBX)
High pass filter, user-controllable in 1 Hz steps between 20Hz and
3KHz; 12 dB/octave roll-off
Low pass filter, user-controllable in 1 Hz steps between 1 KHz and 20
KHz; 12 dB/octave roll-off
Resolution: 1 Hz from 20 Hz to 20 KHz in FBX and parametric mode
Time required to find and eliminate feedback: user-controllable from 0.2
seconds to 1 second (typically 0.3 seconds).
Total number of combined filters active per channel: user-selectable, 0
- 12; plus low and high pass shelving filters
Filters controllable via table or graphic interface
