RDL EZ-HK1 Stereo Audio Hum Killer

Stop audio hum at the source — the Radio Design Labs EZ-HK1 audio isolation module delivers clean, reliable stereo audio for AV, security and surveillance installations. Designed for use between unbalanced, high-impedance consumer sources (computers, CD players, recorders) and grounded amplifiers, the EZ-HK1 provides stereo galvanic isolation that prevents ground-loop noise and protects downstream equipment. Inputs and outputs use gold-plated RCA jacks with optional mini-jack conversion, and a switch-selectable ground-lift ties output shields to chassis only when needed for optimal grounding. At just 3" depth and 2.9" width, and weighing only 4.08 oz, this portable module is ideal for permanent rack installations or mobile monitoring kits. Integrators and installers will appreciate the straightforward hookup, durable connectors and the 3-year limited warranty that supports long-term deployments in pro sound masking, monitoring, surveillance and security audio systems. Reduce troubleshooting time and improve audio clarity across your network—add the RDL EZ-HK1 to your next project or field kit.
