Digital CATV Ground Isolator

 

75-504D | The Calrad 75-504D digital cable TV ground isolator hum/buzz/noise eliminator provides protection against 60hz ground currents created when electrical grounds from two different areas electrically come together, the 75-504D provides a high resistive isolation between the two grounds, preventing rolling bars or buzzing in your audio. The best location for the 75-504D is at the head end of the CATV source from the cable company, if you still experience issues, you will have to add a 75-504D at any location that uses a CATV box and that still has ground loop issues. Compatible with high speed internet and interactive digital cable boxes. Please Note! that this device will not pass DC power.
