Microphone Positioning - How to Reduce
Feedback
Feedback is the annoying howling and squealing
that is heard when the microphone gets too
close to the speaker and the volume is high. You
get feedback when the microphone picks up
the amplified signal from the speaker, and then
amplifies through the speaker again, and then picks
it up again, and so on and so on. In general, it is
always recommended that any LIVE mic (a mic that’s
on) is positioned behind the speaker enclosures. This
will give you the best level from your system before

feedback. One possible exception is when you are
adjusting the sounds of the microphones, since
you want to listen in front of the speaker to hear
properly. To do this, lower your mixers MASTER
VOLUME while setting the EQ and effect from in
front of the speakers. Once you have the sound you
like, move the microphones to behind the speakers
and raise the MASTER volume.
Speaker Placement
Whenever possible, it is a good idea to raise the
speakers above the heads of the listening audience.
The XP308i enclosures’ feature standard 1 3/8” pole
mount receptacles, which are compatible with
speaker stands from a variety of manufacturers
including the models LS2, TS50 and TS100 from
Samson. In a smaller setting like a school cafeteria,
library, or a mall kiosk, you can also use the XP308i
on its side in the tilt back monitor position, which
will improve the projection of the speakers and may
eliminate the need for speaker stands.
