Morley Hum-X Reviews

Can completely eliminate ground loop hum

By George
Rated 5 out of 5
Date: 2025-08-11

We have a TV with connected gaming PC and stereo amp, but these devices are plugged into different power outlets which was causing a ground loop hum. The Hum Exterminator solved this problem completely when installed on the audio amplifier power cord. There can be many causes of audio hum, but if it is a ground loop problem then this device can solve it. Fairly expensive for what I assume is a simple device inside, but worth it to solve this problem easily while maintaining ground protection.
