What does it mean if my stereo turns itself off at a certain volume?

Question

If i am playing my stereo, (a large aiwa with phono/video/aux/cd/etc... inputs), and I reach a certain volume the entire stereo turns itself off. It then proceeds to turn on and off rapidly, as if it is shorting out. It seems to be an internal problem, with the stereo itself and not my speakers.

Answer 1

Without knowing the exact model number of your system, or w/o knowing the model of speakers you're using. My beest guess is that you're over driving your speakers. If they aren't able to handle the power output of the system driving it, it can pull your final amplifiers inside the Aiwa system and cause it to begin over heating. Which in turn can cause the system to shut on and off rapidly until the final amps recover from this over power condition. I wouldn't do this again as it could cause an internal failure that could be very costly to repair.

First - check the speaker wires. Look behind the speakers and behind the receiver. You may have a thin thread of copper sticking out causing a short. When you turn the volume up, the receiver over-heats and starts shutting down to prevent a fire.

And as FireFed pointed out - your speakers may be drawing too much current at high volume which is over-heating the receiver. Keep the volume down.
