When there is a problem consult this guide first. If the problem persists, or you have additional questions, call your local Niles dealer or Niles Technical Support at 1-800-289-4434. The most common problems relate to hook up. Call from your telephone extension nearest the system.

SYMPTOM

POSSIBLE CAUSES AND TEST PROCEDURE

No sound on one channel

Short circuit or loose wire at the speaker or amplifi-

 

er 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.
