Dual Channel Ground Loop Isolator
Ground loop problems in A/V systems normally appear as hum in speakers or horizontal bars on video monitors. These problems typically occur when multiple components receive AC power from different locations, or because CATV, satellite or antenna systems provide a separate ground point. This isolator solves that problem by providing ground path isolation between components, while maintaining full frequency response.

    • "Very well made" by installpro on 6/18/2009

      This product is very well made, if not for the RCA connectors, it would look like it was designed for stage use! Very heavy duty case, heavy substantial feel. Most importantly, IT WORKS! We run into more and more installations where there are ground loop issues at the subwoofer. This does the job every time, with no noticable change in freq response. We now keep 10 or 12 in each van at all times, just in case. If you are running unbalanced line level audio, and have ground loop problems, this will solve it. Every time.
