● Check the balance control on the receiver. Make sure it is centered.
●
Loose connection at either the receiver or the speaker. Double check connections.
● Bad speaker cable. Replace suspect speaker cable.
Receiver cuts on and off:
● This could be caused by a short circuit between the positive and negative leads.
Check the connections at the back of the receiver, and then at the speaker; make
sure that no strands of wire from one connector are touching the other connector.
10) Caring For Your Ceiling Speakers
The two most common ways that ceiling speakers are permanently damaged:
1) Not enough power at higher volumes.
2) Too much power at higher volumes.
Contrary to conventional wisdom, far more speakers are damaged as a result of under-powering,
than by overpowering. When a receiver runs out of power, it still tries to reproduce the musical
signal by “clipping” the waveform. At high volume levels this clipping introduces gross amounts of
distortion to the speaker, eventually destroying it. If the sound from your ceiling speakers starts to
sound distorted, turn down the volume.
Having plenty of reserve power will help your speakers reproduce dynamic contrasts and quick
transients of music much more effectively, but you do have to exercise good judgment; too much
power will also permanently damage a speaker. Again, if you hear distortion, turn the volume down.
