roaddog359 Posted October 20, 2019 Share Posted October 20, 2019 I have been having a constant hum in my system that I cant figure out and get rid of. Its in my side surround speaker when the tv is playing through it. And while trying to trouble shoot it i noticed a hum in my center channel when i run the xbox 360. How can I get rid of the hum? Will XLR balanced connectors solve the issue, running those from my amps to my Marantz SR8012? Any ideas or help will be appreciated. And if XLR cables are my answer can you point me into a good cable for my 7.2 system? Quote Link to comment Share on other sites More sharing options...

Thaddeus Smith Posted October 21, 2019 Share Posted October 21, 2019 Start here: https://www.audioholics.com/home-theater-connection/ground-loops-eliminating-system-hum-and-buzz I can certainly empathize. I've been dealing with a sporadic hum for over a year now. Currently, I'm in a state of "unable to replicate." Quote Link to comment Share on other sites More sharing options...
WorkingEdge Posted October 21, 2019 Share Posted October 21, 2019 My hum came from ground loop caused by Charter TV coaxial cable. Ground loop isolator from Amazon helped a lot. Discontinuing cable helped even more! 1 Quote Link to comment Share on other sites More sharing options...
Peter P. Posted October 21, 2019 Share Posted October 21, 2019 Sometimes its just your speaker cables running too close to A.C. wiring, and/or running parallel to the A.C. wiring. The longer the speaker wires run adjacent to A.C. wiring, the more potential there is for hum to occur. If your speaker wires are inside the walls, this could be a problem to fix. If your speaker wires are inside the walls, try running a temporary speaker wire to the affected speaker by just laying it on the floor in a random route. If your speaker wires are accessible, try the same experiment to see if it's the proximity of your speaker wires to something else which is causing your problem.

nitrofan Posted October 21, 2019 Share Posted October 21, 2019 Seems like cable TV coax is the number one culprit for these problems Quote Link to comment Share on other sites More sharing options...
roaddog359 Posted October 21, 2019 Author Share Posted October 21, 2019 What type of ground loop isolator do I get for the coax tv? Also I noticed when i turn the xbox 360 on I get a loud hum over the center channel. So at least 2 speakers are having hum issue when a source is on and going through the marantz. The center = xbox360 and the left side channel =tv Quote Link to comment Share on other sites More sharing options...
WorkingEdge Posted October 22, 2019 Share Posted October 22, 2019 Got from Amazon. About 20 bucks. Quote Link to comment Share on other sites More sharing options...
