SYMPTOM

POSSIBLE CAUSES AND TEST PROCEDURE

No sound on one channel

BusMatrix DIP switch is not in the correct position.

 

Check your configuration worksheet for the correct

 

setting and verify.

 

Short circuit or loose wire at speaker or amplifier

 

terminals. Check that connections are secure and

 

that there are no loose strands of wire crossing from

 

the positive to the negative terminal at the back of

 

the amplifier and the speaker.

 

Short circuit or a break in the speaker wire. Dis-

 

connect the speaker wire at both ends, separate the

 

2 conductors at both ends and test with a meter for

 

a short circuit. If there is no short, connect the two

 

conductors at one end and test with a meter for

 

continuity.

 

Speaker is not working. Connect the speaker to a

 

channel that plays another speaker.

 

Audio cable to dedicated input is bad. Connect the

 

non-working channel input to another cable that is

 

known to be good.

 

Bridging Switch is in the wrong position. Check

 

your configuration worksheet for the correct setting

 

and verify.

 

The thermal protection circuit has operated because

 

of overheating caused by overdriving or inadequate

 

ventilation.

 

 

No sound on some or all

BusMatrix DIP switches are not in the correct posi-

channels

tions. Check your configuration worksheet and

 

verify all settings.

 

Audio cable to the main bus inputs is bad. Connect

 

the non-working channel input to another cable

 

that is known to be good.

 

Some or all of the internal amplifier fuses are blown.

 

(Return the amplifier to your dealer for service).
