Hum eliminators work best when interference causes small differences in ground potential (less than 20 VDC) or long cable runs have induced currents. HEC series units also work well when there are multiple power panels in a building that create differences in ground potential which induce ground loop current flow and 60 Hz hum.
- ABS Plastic Housing
- Lightweight construction of hard plastic is strong and non conductive.
- 75 ohm BNC Connectors
- 75 ohm impedance is the standard for quality video connectors and BNC is the professional's preferred connection.
