Dayton DTA-100A high pitch noise

post #1 of 4
Thread Starter 
Last night I started getting a high pitch noise, almost like a screech when I use my amp. It's especially bad at anything past 9 o'clock. I would assume it's a bad ground or something but I don't know what exactly to look for. Any suggestions? The amp is only a week old.

From a quick search your right to think that it might be a grounding issue, I'm not sure how to check for this either.

 

This is the first time I've heard about having to ground a subwoofer, and it does make me a little wary of having issues when I decide to get one.

It's not the subwoofer though. The amp is causing it, I get the wine through the bookshelf speakers.

It has to be something related to the PC. If the 3.5mm is plugged in to the sound card it does it. If I unplug the 3.5mm from the sound card it doesn't.
