I have or had an annoying ground loop between ;-) AV receiver, satellite receiver, TV, BluRay player and an active subwoofer, which ultimately only by withdrawing the Chinchverbindungen (2x Line-In on the sub-Woogfer, 2x Pre -Out subwoofer let eliminate the AV receiver). The only way I got calm.
After several failed attempts (turn plug, connect satellite receivers over Tosslink cable to the receiver, try another outlet etc.) to eliminate the annoying ground loop, I gave up and bought myself the ground loop isolator.
The delivery took place in a flash, and just as quickly, the ground loop was eliminated at my active subwoofer! Peace at last! Plugged device via the RCA connections between and everything was done. Peace!
The device has a solid metal casing, the Chinch plug are processed with value and the cables are double-shielded.
I can only put the device each warmly which certainly wants to launch a ground loop to silence and a dibasic processed device searches. A loss in the tone I could not find the way!
