The HEC-2000-V IS A single-channel Hum Eliminators manufactured by Allen Avionics. The HEC-2000 Series is designed to eliminate hum in video applications caused by long cable runs or ground loops. The HEC series works in circumstances where interference is caused by small differences in ground potential (less than 20 volts) or by induced currents in long cable runs. When there are multiple power panels in a building, or even a single floor, equipment and lighting loads result in small differences in potential which induce a ground loop current flow and 60 Hz hum. Electronically-induced current flows in long cable runs also create hum.
