Problem Cause Solution
Why isn’t my
amplifier powering
up, even though I
have tried turning
it on and off? The device may have
overheated. Turn your amplifier off. Wait until it
cools down and try again.
The fuse might be blown. Check the amplifier’s fuse and
replace it if necessary.
The speakers might not be
connected properly. Check all connections.
Why can’t I hear
anything? The amplifier’s LEFT and RIGHT
VOLUME, MIC1, MIC2, MIC3,
MIC4/PHONO, or CD/AUX
controls might be on their
minimum settings. Adjust the volume control to the
desired setting.
The speakers might not be
connected properly. Check all connections.
A microphone or cable might
be faulty. Check all microphones and cables.
The speakers might be the
wrong impedance for the PA. Make sure your speaker wires are
18-gauge [for wire length up to
7.6 m (25 ft)]. For best results, use
the shortest length of speaker wire
possible.
The amplifier might have shut
down. Turn the amplifier off and let it cool
down. Make sure the amplifier is
properly vented, then turn it back
on.
Why am I hearing
feedback? The FEEDBACK FILTER might
need to be adjusted. Turn the FEEDBACK FILTER
clockwise until you reduce or
eliminate feedback.
Your microphones or speakers
could be too close together. Reposition the microphones and
speakers.
