  • The EZ-HK3 is a superior-quality stereo audio and composite video transformer isolation module for use with unbalanced, high impedance audio inputs and standard 75 ohm composite video. Input and output connections are provided on gold-plated RCA jacks. The shield connection of each INPUT jack is electrically isolated from the case and from the output ground. The shield connection of each OUTPUT jack is connected to the case shield through a rear-panel ground-lift switch. The EZ-HK3 eliminates hum due to ground loops when it is installed between an unbalanced audio/video source, such as a computer or DVD player, and the input of a grounded amplifier and video monitor or projector in an A/V system.
