amplifier terminals. Check that the connections are

 

secure and that there are no loose strands of wire

 

crossing from the positive to the negative terminals

 

at the back of the amplifier and /or 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 input is bad. Connect another cable

 

that is known to be good.

 

 

No sound on both channels

Audio cable to the main inputs is bad. Connect

 

another cable that is known to be good.

 

 

Hum from the speakers

Hum may be caused by a ground loop between

 

two of the other components in the system. To test

 

for another ground loop, try reversing the AC plugs

 

of each of the components in the system.
