GROUND ZERO is an affordable totally passive star grounding system that equalizes the ground impedance path of every component in your audio or video system regardless of the condition of your house wiring and regardless of how many different gauges of power cords you are using.
The ground potential of one component may be higher or lower than that of another connected component and the component's ground path to earth ground, or ground impedance, may be higher or lower than that of the other connected component.
The ground bond created by the interconnect shields is problematic because of the small gauge of the wires, dirty contact surfaces, and the sometimes low mechanical integrity of the outer grounding ring of cheaper RCA plugs.
