ˆ Troubleshooting
If you should run into difficulties, check
the wiring of the system. Are there any
short circuits in the speaker wiring?
Have you provided adequate ventila-
tion? Did you calculate speaker imped-
ance correctly?
Be sure microphones and connecting
cables are not defective.
Be sure you are using large enough
speaker wire. You should always use
16-gauge (or larger) wire. The longer the
run of speaker wire, the heavier the
gauge should be.
If you have feedback problems, reposi-
tion your microphones and speakers, or
adjust to a lower set-
MASTER VOLUME
ting.
If the amplifier does not work at all,
check the fuse on the rear panel. If it is
blown, replace it with one of the same
size and type (see "Replacing the Fuse"
on Page 14).
If you cannot solve the problem, contact
your local RadioShack store for assis-
tance.
