FEEDBACK: A LOUD SQUEALING, SHRILL OR HOWLING
SOUND THAT IS SELF GENERATED

Feedback occurs when a microphone is too close to the
speaker or the microphone volume is too high, or the
microphone is pointed towards the speaker. It is also caused
by sound reflecting off hard surfaces.
·
Reduce or eliminate Feedback by
- Pointing the microphone in a different direction
- Keeping the microphone BEHIND the speakers
- Turn down the volume levels

plugged into the AC outlet for several hours. After a
year or two the battery may need to be replaced. Batter-
ies are available from Amplivox.

To replace the batteries use a Phillips screwdriver and
take out the 3 screws from each battery cover (there are
two batteries) on the back panel. Remove the foam
spacer, set aside. Pull out the batteries to access the
terminals.

Carefully hold the battery with one hand while you re-
move the mating connector. Replace with new battery
and push mating connector of battery wire onto the cor-
responding color/polarity. RED = POSITIVE, BLACK =
NEGATIVE.
