When there is a problem consult this guide first. If the problem persists, or you have additional questions, call your local Niles dealer or call Niles Technical Support at 1-800-289-4434. The most common problems relate to hook up. Have your configuration worksheet handy when you call.

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. Disconnect 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 over driving or inadequate ventilation.

No sound on some or all channels

BusMatrix™ DIP switches are not in the correct positions. 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).

 

 

Hum may be caused by a ground loop between two components in the system. Test for a

 

 

Hum from all the

ground loop by reversing the AC plugs of any components in the system with non polarized AC

 

plugs.
