Do you happen to have subwoofer channel settings on the receiver itself also? I had the problem you did originally, because I had my Denon receiver at +3 on the sub channel and the gain on the sub itself was at about 1/3. Was too much.
Sorry, there was a problem. Please try again later.It could be the ground wire on your plug in I've had issues with that in the past
Sorry, there was a problem. Please try again later.Run a single harness from your sub out on your receiver to your LINE IN L/LFE on your sub. I was told to return the speaker two times, problem was till there. Then I was told that my house grounds were no good. Turned out to That I was using the wrong plug in on the sub.
Sorry, there was a problem. Please try again later.It's likely a grounding issue - that's called a "ground hum" created by a ground loop in your electrical system. If you go on-line and type in "ground hum" - you'll see a variety of sites that can lead you through fixes - and also low cost products to eliminate ground hum. Its a fairly common problem. Good luck!
Sorry, there was a problem. Please try again later.I am not sure in your case but I had the same issue when I switched from Denon to Pioneer receiver. I ended up returning the Pioneer and got another Denon and the humming noises went away.
Sorry, there was a problem. Please try again later.I too have the same problem. It gives that buzzing sound when I connect the audio cable, even if the other end is not connected to the receiver. I upgraded my receiver, changed the audio cable by thinking that it may be the problem. Still having the same. It's annoying. Today I called Klipsch support. They told me to open a ticket with the receipt/bill. They probably want to sent me a new amplifier for the same which they say I can change it myself at home. Don't know what to do.
Sorry, there was a problem. Please try again later.
