Sub hum, beebing noise.

[Seth=L]

Now, I know it isn't the amplifier. That is unless I have two subs with the exact same problem. I had a KLH 8" powered woofer, I know it is crap hence why I call it a powered woofer. It would do this strange thing where it would beeb/hum at any point while it was on, being driven hard, easy, or not at all. I thought there was something wrong with it, so I returned it.

Well I have another sub now. It is a 12" RCA/Tandy/Optimus Subwoofer with a 120 watt rms amplifier. It is doing the same exact thing.

Notes: I am using a different receiver than I was with the KLH, I am using an AudioQuest sub cable and y-adapter. It is a stationary two prong power cord design. It is plugged into a Magnavox power tap that has all my other audio components conected to it listed in my signature. (though the KLH happened to be conected to a seperate outlet from the main system) All my components have stationary 2 prong power cables.

If there is any other helpful info you need, I would be more than happy to type twenty paragraphs to explain everything, though I would rather not.

I'm having a similar problem. It first started around when I setup my 6.2 (added the second sub) but now its continued. I think its from having all the components on 1 outlet (or breaker). My room is awful in this regard, 1 15A breaker split between my room, a built in vaccum, fridge/freezer, and another room's outlets.

I wonder if that my be my problem. How often does yours do it?

Any time my DVD player is loading a new screen or I hit enter, skip, etc it bumps. My PC USED to do it, but I replaced the cable form my digital out and it seems to have stopped. It will also do it when I swtich inputs or hit the mute button.

I think my receiver is about to go, but its old anyway, time for descrete 7.1!

You seem to be gettting tired, lots of typo's.

Mine does it anytime it feels like it. It gradually comes in with a beebing hum becoming increasingly more annoying, like swarm of Canadian mosquitoes, and then it dissipates. It will do it while I am watching something or when there isn't any source being fed to it (while it is still on, it has an auto shut off). And as I said before the KLH I had before did exactly the same thing with a completely different receiver.

I think it's about time you updated your source. Pro logic?!?

My source would be a DVD player. I have on-board Dolby 5.1 decoding.

As for my receiver, It has Dolby EX and DTS-ES.

Did you like the bit about the mosquitoes?
