That's a real problem. Unplug all of your audio inputs and see if the hum is still there. If it is, you will need to exchange your receiver for a new one or fix the one you have. This hum normally comes from a ground bounce from your audio inputs from things like a cd player or other audio component. If you find the hum coming from one of the other components, then you can blame that. It is unlikely a speaker issue with normal speakers.
Sorry, there was a problem. Please try again later.Try moving the electrical cord to a different outlet, or plugging it into a surge suppressor, try putting a ferrite filter on the AC cord just before it goes into the receiver.
Sorry, there was a problem. Please try again later.I would look up this question on the internet via an audio/electrical forum. I don't think you would get a proper response from your average BestBuy customer (like me). Not to say that you may get a good answer.
Sorry, there was a problem. Please try again later.If this is a consistent issue one of three conditions exist. Your speakers may need a different power requirement (you may need more power or less power) (like 20 watt speakers being driven by 200 watt amp will cause problems); your speakers could be blown for some unknown reason. And, finally there could be a problem with the amp itself. Can you troubleshoot with a different set of speakers?
