Check connections. Are input and output reversed? Is
the POWER-Q LED showing signal? If no, make sure the
unit is not in BYPASS mode, and that audio signal is
feeding POWER-Q input. If yes, check connections and
gain downstream from POWER-Q.
Check POWER-Q noise gate settings. Check connec-
tions for intermittence.
Check POWER-Q compression settings.
Check POWER-Q delay settings.
Check filter availability. Check "Persistence" and "Sensi-
tivity" settings. Make sure unit is not in BYPASS.
Check reference mic, mic cable, connections, and phan-
tom power. Make sure audio signal is playing through the
POWER-Q.
See Section 7.2. If you have the POWER-Q patched in an
effects or auxiliary loop, you will only catch the feedback in
the effects loop, and not the mixer input channel. Or, you
may have used up all the available FBX filters, leaving no
additional filters for new feedback frequencies.
Try using a graphic equalizer to "flatten" the room. There
may be a big frequency "bump" in a room with less than
ideal acoustics; this is better treated with a wider filter.
Most likely you are pushing a VERY HOT signal into the
box. It's hard to make the POWER-Q clip. Check con-
nections for intermittence, or check downstream from the
POWER-Q. Check the POWER-Q "Digital Clip Level" in
the "Global Parameters" window and turn it up, or adjust
"Clip Adjust" to "AUTO." ALTERNATIVELY: The POWER-
Q may still be in "TURBO" mode, which automatically
maximizes the Clip Level until the first dynamic FBX filter
is set. You may exit "TURBO" mode in several ways (see
section 11.2).
Bypass the POWER-Q. If noise is still there, it's not the
POWER-Q. If noise goes away, check the POWER-Q
"Digital Clip Level" and turn it up, or adjust Clip Adjust to
"CLIPGUARD."
Check the reference microphone you're using and make
sure it's flat. Consider the reference microphone position
and experiment.
Take up a useful hobby like stamp collecting. Get out more
often. Be glad you don't have to write one.... or do the page
layout.
