![]() ![]() The ground loop isolator terminates ground loop currents in a cable and blocks the hum and interference carried in the ground loop. ![]() This equipment interprets this interference as part of the video signal and displays it on the monitor as a rolling “hum bar”. The VRD-1FF is a video isolator designed specifically for 75 ohm CATV lines, analog or digital (not satellite-friendly). Devices called ground isolators solve the fundamental problem with. The current flows through the shield of coaxial cable and it picks the interference up and carries it to the inputs of CCTV equipment. Telephone, CATV, and satellite TV cables are also. Because there is multiple ground paths, loops are formed in which current can flow. Installation of the Lemar Video Ground Loop Isolator rescues you from the irritation of tearing apart your setup as you search for the source of irritating signal disturbances such as those caused by loops or wiring laid too near power lines.Īlso provides for better surge protection, while convenience of installation means the Lemar Video Ground Loop Isolator is easily added to previously existing operations.Īn earth loop interference may occur when there is more that one ground or earth between two pieces of equipment. Then, unscrew the ground loop screw on the back of your subwoofer.Our Video Ground Loop Isolator is a necessary part of every CCTV setup, providing improved security from troublesome ground loop distortion.
