SECTION THREE — ENGINEERING SPECIFICATIONS
FILTERS
• 12 independent digital notch fil-
ters per channel, controlled auto-
matically from 40 Hz to 20 KHz.
• Filter width: user-controllable - ei-
ther 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 fil-
ters 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.

IMPORTANT NOTE
• Mixing balanced and unbal-
anced connections may result
in a 6 dB loss of gain.
Y Insert Cords (TRS to TS + TS)

IMPORTANT NOTE
• Use a ¼-inch TRS plug for
balanced sends/inserts.
• Use a ¼-inch TS plug for
unbalanced sends/inserts.
• Mixing balanced and unbal-
anced connections may result
in a 6 dB loss of gain.
