to maximum by pressing and holding the
Volume Up button until the microphone stops
beeping.
f. Slowly raise the microphone gain level
on the PVS switcher while talking into the
microphone until feedback occurs. One click
of the encoder is 1 dB. The dynamic filters
begin to engage and to eliminate feedback. If
the feedback persists, lower the microphone
gain on the switcher until the feedback stops.
g. To set additional filters, walk around the
room while talking into the microphone. If the
feedback persists, lower the microphone gain
on the switcher and walk around the room
again.
