FILTERS
• 12 independent digital notch
filters per channel, controlled au-
tomatically from 40 Hz to 20 KHz.
• Filter width: user-controllable - either
1/10 or 1/5 octave*, constant "Q"
• Resolution: 1 Hz
• Time required to find and eliminate
feedback: 0.4 seconds, typical @ 1
KHz
• Number of Dynamic vs. Fixed
filters per channel: user select-
able. Last configuration stored in
memory.
*Below approximately 200 Hz the feedback filters
become slightly wider to increase the feedback and
rumble capture speed at these low frequencies.
