ProCo Sound GLX Balanced XLR Ground Lift Adapter

The ProCo Sound GLX is a ground lift adapter designed for audio engineers and systems integrators who need to eliminate hum and buzz caused by ground loops on balanced XLR lines. Ground loop interference is a persistent problem in installed audio environments, multi-console touring setups, and broadcast signal chains where equipment shares power from different circuits or grounding paths. Rather than reaching for a direct box or rewiring a loom, the GLX drops inline at any XLR junction point to break the ground path cleanly.

The XLRF-to-XLRM configuration means the GLX inserts anywhere in a standard balanced line without adapters or gender changers — between a console output and a stage snake, at a drive rack input, or anywhere a ground-loop-induced noise floor issue needs a fast, passive fix. For systems integrators commissioning permanent installs, the GLX provides a reliable, compact solution that stores and deploys with no tools required.
