GLI-35XLR | 3.5mm to XLR Ground Loop Noise Isolator with Volume Control & GND Switch

The GLI-35XLR is a passive Ground Loop Noise isolator designed to remove hum, buzz, and unwanted interference in audio systems. Ground loop noise occurs when interconnected audio devices have different ground potentials, causing electrical currents that result in audible noise. This problem is often found when consumer audio sources—such as smartphones, laptops, and audio interfaces—are connected to professional sound systems like mixers, PA systems, and recording equipment. The GLI-35XLR provides a reliable solution for Musicians, Audio Engineers, Content Creators, and AV Technicians who need a Clear Audio Signal when linking unbalanced 3.5mm devices to balanced XLR equipment in Live Sound, Studio Recording, and Broadcasting Setups.

This XLR ground loop noise isolator includes a 3.5mm (Female) input and an XLR (Male) output, allowing smooth integration between unbalanced and balanced audio systems. A GND ON/OFF switch helps manage grounding issues, reducing interference when necessary. Additionally, a rotary volume control knob enables manual adjustment of output levels, offering flexibility in different environments. Designed with a high-quality transformer, durable metal housing, and a Uni-Directional Signal Path, the GLI-35XLR helps ensure Clean Audio Transmission in professional and home setups. The combination of ground loop isolation, a Grounding Switch, and Volume Control makes it a practical tool for those working with mixed audio systems, helping to minimize noise and maintain signal integrity.
