Hello All,
I am having a bit of a problem. I have an Onkyo 605, av123 x-ls, and x-cs. I had these set up for a week or so and did not notice any buzzing, I finally set up my x-sub tonight and all the speakers started to buzz once I hooked up the sub. Does anyone know what is going on? Help is appreciated!

Thanks!
Eddie

What you are describing sounds like a ground loop. Sometimes ground loops are tricking to fix. When you unplug the sub does the buzzing go away?

yup after I unplug the sub the sound goes away, I tried something and it seem to have gone away. I have an 2 prong extention cord and I plugged that into the wall then I plugged to sub into the extention without plugging in the 3rd big round prong on the sub power cable and the buzz seems to have gone away. Am I good now?

Thanks!
Eddie
