ˆTroubleshooting

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 TONE or MASTER VOLUME to a lower setting.

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 Fuses” on Page 13).

If you are operating the unit from a 12- volt DC power source, check the fuse in the supplied cable that connects to your vehicle’s 12-volt accessory socket. If the fuse is blown, replace it with a 4-amp 125-volt fuse (see “Replacing Fuses” on Page 13).

If you cannot solve the problem, contact your local RadioShack store for assis- tance.
