9. Feedback during a performance is usually caused by one of the monitors. The
main PA is less likely to feed back because the mics are so far away from the
main PA speakers. Therefore, if you are using monitors and feedback occurs, try
the following procedures:
i.
Turn the
MONITOR
master down until the feedback stops.
ii. If you have a graphic equalizer patched between the
MONITOR
output
and your monitor power amp, pull down one or two (but not more) of
the
EQ
sliders in the frequency range where the sound seems to be
occurring.
iii. Now turn the
MONITOR
master back up. If the feedback recurs, push
the
EQ
slider/s back up to center position and try pulling down one or
two others.
iv. In the rare case of main system feedback, follow the above type of
procedure, but using the
MAIN
master and the built in
GRAPHIC EQ
.
