Title: Buzz + Ground Loop Issue: SOLVED Post by HiFi Bri on 10/04/24 at 17:47:14 Posting this here just in case others find it helpful. For several months, I've been struggling with identifying the source of a faint buzz coming from my speaker drivers, even when everything was powered off. I've tried swapping cables, lifting the ground with a cheater plug, and various products like the Snubway, to no avail. I recently added a pair of Omega Deep Hemp subwoofers to my system which made the buzz even louder and harder to ignore. After combing through various forums for answers, chatting with Louis from Omega, and emailing Steve, I was finally able to identify the issue and eliminate the buzz. May seem obvious to some, but it was a ground loop causing the buzz. Here was my fix:
Now, my system is quiet as a mouse. |

Connecting a wire between the two negative speaker posts, I got that. Then you say "I connected one of those to a screw on the chassis." Do you mean using another wire, you connected one end to a negative speaker post and the other end to the chassis? |
