Axiom Home Page Forums General Discussion Technical Questions Computer-to-receiver hum

Definitely a ground loop issue, years ago when I would connect my PCs to the receiver with an analog connection the same thing would happen. I put the PC on a UPS and it seemed to break the ground loop and worked fine. If you did have a digital output you probably wouldn't have the issue (esp with optical interlink).

I am curious thou, whats teh Y cable doing in this senerio?
