The Ocean Matrix VHE-14-RM 14-Channel Rack Mount Video Hum Eliminator is designed to remove ground loop interference created by long cable runs, 60 cycle power demands, and magnetic coupling. Normal voltage differences between system grounding points causes small currents to flow through video cables allowing a visible hum bar. A high impedance choke in the ground path of each channel effectively removes the hum from the cable.
This Hum Eliminator is housed in a 2U rack mount enclosure. All channels are separate and isolated from each other as well as the enclosure. This allows each channel to work as an independent unit. A frequency response of 150 MHz makes this eliminator suitable for high-definition systems. The unit is passive, and removes hum without any external power source.
