FILTERS
• 12 independent digital notch filters per channel, controlled automati-
cally 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 selectable.
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.
**Tests performed using an Audio Precision System One model 322 or equal.
