•  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.

•  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.

•  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.

•  You have a broken finger.
