Bad.sound!
• Is it loud and distorted? Follow the procedures
described in the “Quick Start” section to verify
that the levels are set properly.
• Are all the connections secure? It’s a good
idea to periodically clean all electrical connec-
tions with a non-lubricating electrical contact
cleaner.
• Keep practicing.

Troubleshooting
No.sound!
• Are the level controls on the mixer or am-
plifier turned all the way down? Follow the
procedures in the “Quick Start” section on
page  to verify that all the volume controls in
the system are properly adjusted.
• Is the signal source working (and making union
scale)? Make sure all the connecting cables are
in good repair and securely connected at both
ends.

• Are the level controls set the same for both
channels on the mixer and amplifier?
• Check the PAN control on the signal source. It
may be turned too far to one side. If you’re us-
ing a stereo signal source, it may be delivering
an out-of-balance stereo signal.
• Try swapping sides: Switch the speaker cables
coming from the amplifier at the amplifier end.
If the other side is louder now, the problem
is with the amplifier, the mixer, or the signal
source.
Poor.bass.performance
• Check the polarity of the connections between
the amplifier and the loudspeakers. You may
have your positive and negative connections
reversed at one end of one cable.
