Nikym81 7 Posted December 24, 2020 Share Posted December 24, 2020 Hey guys! I've just finished setting up my speakers in my home theatre and only one speaker (rear right) is making a hum sound which is driving me crazy. All the others are fine and hum-less. The hum stops when I disconnect the cables to that speaker from the receiver. It's a denon x2500h receiver and dali zensor speakers. Is it a receiver fault, speaker fault, or something in the cabling to that speaker? Cables are in wall. Link to post Share on other sites
Bill125812 3,568 Posted December 25, 2020 Share Posted December 25, 2020 My first suggestion would be to plug the cables going to the speaker with the hum into another speaker. That will eliminate the speaker being at fault Link to post Share on other sites
Nikym81 7 Posted December 25, 2020 Author Share Posted December 25, 2020 So I've already swapped over cables from another speaker from amp to wall and from wall to speaker and still hums. But that gives me an idea, I might try swapping RL and RR speakers. If still there, I'll plug speaker directly in to amp and try each it on both rear channels, bypassing the in wall cables. 2 Link to post Share on other sites

Process of elimination mate. Sounds like you're onto it though. Those hums are quite annoying and once you know it's there, it's like a scab. Good luck on your quest.

Nikym81 7 Posted December 26, 2020 Author Share Posted December 26, 2020 Success! House frame is metal and the wall plate plug was touching the metal frame. Hum is gone and sanity is back lol. Thanks guys 5 Link to post Share on other sites
