The RDL EZ-HK3 Audio / Video Hum Killer is a high-quality video transformer isolation module. It's designed specifically for use with unbalanced high impedance audio inputs and 75 ohm composite video. The device features both input and output connections on gold-plated RCA jacks. Each input jack is electrically isolated from the case itself, as well as from the output ground. Each output jack is connected to the rear-panel ground-lift switch, which is designed to eliminate hum due to ground loops. Ground loops are common when the EZ-HK3 is installed between a video source, such as a computer or DVD player, and the input of a grounded video monitor or projector in an AV or video system.

Key Features

Composite Video Input
Connect the video output from the audio/video source to the composite video input RCA jack
Stereo Audio Inputs
Connect the audio output from the audio/video source to the RCA jacks
Composite Video Output
Connect the video output to the A/V system or equipment video input
Stereo Audio Outputs
Connect the audio outputs to the A/V system or equipment audio input
Ground-Lift Switch
The audio and video output cable shields are connected to the EZ-HK3 chassis when the switch is in the NORM position. In the unlikely event that the EZ-HK3 chassis is mounted to equipment with a different ground from the equipment the EZ-HK3 output is feeding, a ground loop could be produced. This ground loop is eliminated by setting the switch to the LIFT position
