AV Link Ground Loop Isolator

Product Information

I’m happy to say that this completely fixed the constant computer noise that was coming through my USB cable to my Focusrite Solo and I am now sitting in blissful silence for the first time in forever! Even if all of the audio and video equipment in, for example, a home theatre system is plugged into the same power outlet, and thus all share the same ground, the coaxial cable entering the TV may be grounded by the cable company to a different point than that of the house's electrical ground creating a ground loop, and causing undesirable mains hum in the system's speakers. Signal is transmitted 1:1 with separated ground • Inputs: 2x Phono (RCA) L/R Sockets • Outputs: 2x Phono (RCA) . A hazardous technique sometimes used by amateurs is to break the third wire ground conductor P in one of the component's power cords, by removing the ground pin on the plug, or using a cheater plug.

If you can’t imagine spending hundreds or thousands on multiple variations of audio components, you actually don’t have to.

Ground loop noise and hum also affect video systems, although in that case, the noise often appears as distortion in the video signal. This forms a closed loop through the ground conductors of the power cords, which are connected through the building wiring.

Computers can generate a lot of RFI, which is why I shy away from cases with see-through plastic sides, which allow RFI to travel both ways. Addition of signal interconnection cables to a system where equipment enclosures are already required to be bonded to ground can create ground loops. As a result, if a current ( I 1 {\displaystyle \scriptstyle I_{1}} ) is flowing through R G {\displaystyle \scriptstyle R_{G}} from circuit 1, then a voltage drop across R G {\displaystyle \scriptstyle R_{G}} of V G = I 1 R G {\displaystyle \scriptstyle V_{G}\;=\;I_{1}R_{G}} occurs, causing the shared ground connection to no longer be at the actual ground potential. In cases where you’re unable to swap out cables or electronics (this is pretty common when working on someone else’s system or when they cannot afford to pay labor costs it may take to resolve it otherwise.I’d been plagued with a low level digital static noise coming from my studio monitors for some time now.
