About the HumZero

The PS Audio HumZero is a compact device designed to eliminate unwanted noise, hum, and buzz in high-end audio and video systems caused by ground loops, particularly from cable TV (CATV), internet modems, or cable boxes. It achieves this through galvanic isolation, separating noisy external grounds from the cleaner internal grounds of your home audio setup without compromising signal integrity. Placed inline between the incoming cable and your modem or cable box, HumZero maintains full electrical safety, unrestricted data rates exceeding 500 Mbps, broadcast-quality video up to 4K Ultra HD, and high-resolution streaming audio support up to 384 kHz/24-bit and beyond. Users report significant improvements in audio clarity, elimination of low-level hums even in high-end systems, and no degradation in picture or audio quality. It is a simple, no-wear-parts solution praised for solving persistent ground contamination issues safely, unlike unsafe cheater plugs.
