Overview
Every installation technician has faced it or soon will - the dreaded humming from the speakers, a telltale sign of a ground loop. Ground loops are caused by voltage potential differences at the ground point on your equipment. Voltages in the range of microvolts up to millivolts or higher can cause ground loops. Ground loops occur when multiple audio/video components are powered from different outlets, most commonly, outlets that are tied to different circuitbreakers or even a different secondary from the power transformer.
Ground loops manifest themselves in the form of speaker hum.
Our isolation transformer easily connects into your audio/video system and breaks the ground path through cables between components. Start at the component last installed before the ground loop was discovered, and connect the isolation transformer at different ends of the audio/video cable until the ground loop is gone. Gold-plated 3.5mm stereo jacks.
Input: 3.5mm Female
Output: 3.5mm Female
Please Note: While this transformer is designed to eliminate ground loops, isolating the source of the ground loop can be very difficult even for professional technicians. Sometimes the problem can be at the last added component or at the furthest from the main system; however, these might only be symptoms of a harder-to-solve problem. Please exercise patience as you work through test scenarios to eliminate your ground loop issue.

Comments about 3.5mm Stereo Audio Isolation Transformer:
I needed something to eliminate the hum from the output of my computer to the input to my HDTV. Before the audible was unusable. Now I get decent sound without having to ground or use the same outlet for the two components.

Comments about 3.5mm Stereo Audio Isolation Transformer:
I use this for a different but related use. When I added an auxiliary line-in to my car's stereo, I found that while it worked great, any device plugged in to the car's 12v circuit would have noise from the alternator and engine electronics added in. Since this is a similar idea to a normal AC 'ground loop', I figured this would provide a good solution. It sure did! Didn't just attenuate the whine and hum, it totally eliminated it. Works as advertised.
