DigitalLife Hum Eliminator | 6.35mm Audio Ground Loop Noise Isolator (1-Pack)

The DigitalLife GLI-635 Hum Eliminator is a professional 6.35mm Audio Ground Loop Isolator designed to eliminate hum, buzz, and ground loop noise between connected audio devices. Using transformer-based signal isolation technology, it helps break unwanted ground loop paths while maintaining audio clarity and signal integrity. Simply connect the isolator between devices equipped with standard 6.35mm (1/4-inch) audio connections to reduce interference and improve overall sound quality.

Ground loop noise commonly occurs when multiple audio devices are connected to different power sources, creating unwanted electrical interference that can introduce humming, buzzing, or low-frequency noise into the audio signal. The DigitalLife GLI-635 Ground Loop Noise Filter helps reduce these issues by isolating the audio signal while preserving natural sound reproduction. Whether you are recording music, performing live, podcasting, streaming, or building a home audio system, this audio hum eliminator helps deliver cleaner and more reliable audio performance.

This passive 6.35mm Ground Loop Isolator is compatible with guitars, amplifiers, audio interfaces, mixers, headphones, powered speakers, sound processors, PA systems, recording equipment, and home audio systems. No external power supply, software, or drivers are required. Please note that this device is specifically designed to reduce noise caused by ground loop issues and is not intended to eliminate noise generated by faulty equipment, defective power supplies, damaged cables, or other unrelated sources.
