Subwoofer making a buzzing vibration noise, NEED HELP PLEASE

post #1 of 9
Thread Starter 
Hey i have a Behringer EP1500 AMP and a Titanic Sub (http://www.parts-express.com/pe/showdetl.cfm?partnumber=295-420). My receiver is a Yamaha RX-V471.

I have a XLR Male to RCA Female Adapter in the back of my amp and i connect the RCA cable from that to the back of my stereo. I am using an RCA cable that i purchased from radio shack. For some reason when i have the amp turned on i am getting a buzzing vibration noise coming from my sub and it will not go away. Now when i turn the Gain Control all the way up that is when it is making that noise. When its only half way i can not seem to hear the noise anymore. It has never done this b4 and i have just recently moved so im not sure if that plays into factor as far as electoral plug outlets and stuff. So i would love if anyone could help me fix this problem i don't know a lot about stereo stuff. Please Help me!?!?!

Thanks, John

Are your amp and sub-woofer plugged into the same AC power outlet strip? You may need a long heavy extension cord to do this.

Really you should use an XLR cable with the adapter at the sub end.

Yes i have them plugged into the same AC power outlet strip. I also tired to run an extension cord to another outlet and that didn't seem to fix the problem. So do you think that it is just the XLR cable?

First off, please explain what a "buzzing vibration" is...confused.gif

Second, the gain on the amp should NEVER be turned up all the way...period...no ands, ifs or buts about it...

And 'C', ground both the Beringer AND the AVR...

4th, double check the electrical system in the new environment has a PROPER ground.

I doubt that an XLR to XLR cable will solve this problem, but it is a better cable plan.

Yea i guess i really didn't word that right. lol. It is more like a humming noise.and the AVR is just a 2 ping plug. Like i said they are both plugged in the same power strip.So what do you mean by ground both of them? Again im not really good with all this my step dad hooked it all up for me and he isn't around anymore. So i appreciate you guys patience and help with me.

Also i thought that the gain control was for turning up when you wanted more bass? Also would one of these maybe fix the problem(http://www.behringer.com/ES/Products/DI100.aspx)?
