Hey again folks,
just recently one of my speakers has started making strange noises. Hard to explain, but it sounds like a mic being plugged in ( if that makes any sense, a sort of crackling sound ) and it is intermittent. I unplugged the cables from the Network Player and plugged them in again and everything was fine for a couple of hours and then it started again. It does not appear to get louder if I increase the volume on the amp. Also, this only happens through the left speaker and only when I am using the Network Player. I don't hear the noise at all when using the CD transport ( which is connected to the Network Player ).
Anyone have any ideas? Do I have yet another defective cable? Do I have a defective speaker? Is the Network Player defective? It is a little annoying as everything is brand new.

Any help would be much appreciated.

David

If the volume control does not affect the loudness, and it is only in the left channel, then it has to be coming from the left channel of the power amplifier (or speaker...not likely).

Anything else would change loudness when the volume control is adjusted.

Your statement that it goes away when the source is changed does not seem to make any sense.

If it was originating in the network player or cable connections, or any source whatsoever, then the volume control would definitely change it, and it would go away completely with the volume turned all the way down.

Thanks commsysman.

It was driving me nuts. I switched the speaker cables over ( plugged the left one into the right side of amp ) and still same noise from left speaker. I changed the cables from the Network player...still same noise. never got louder if I increased the volume but I knew it had to be the Network player somehow as it only happens when I use it.
However, the problem is solved and I didn't expect it to be so simple. I guess the left speaker didn't like a couple of the radio stations I was playing! I tried several other radio stations and so far no problems. I turned it back to the station I usually listen to and within 30 seconds the noise was back again. It never occurred to me that it might be the station I was listening to as I would expect the noise to be from both speakers.
Any idea why only the left speaker would be affected??? Even when I plugged the left speaker into the other side of the amp, the noise was still from that speaker. I really was a bit flummoxed as I suspected it had to be the speaker, then the amp but then narrowed it down to it having to be the network player as it only occurs using that. Weird.

Thanks again. Love this forum. Friendly and helpful folks.
