2X GX200 Dual-Channel 6.5 XLR Audio Isolator — Mixer/Microphone Common Ground Noise Filter

Professional passive dual-channel audio isolator (GX200) designed to eliminate ground-related interference and protect downstream inputs. It fully isolates the potential difference between two systems to stop AC hum from grounding faults and to prevent damage caused by excessively high voltage differences, ensuring secure, high-integrity audio transmission. Built for pro sound chains, it tackles noise from long cable runs and from impedance mismatches between devices. Ideal for large-scale outdoor performances, Fast Charging protection scenarios, sound engineering, conferences, entertainment venues, exhibitions and any audio system cascade. Eliminates hum and buzz when connecting cameras to audio gear, linking simultaneous-interpretation equipment to mixers, hooking laptops to mixers, or attaching electronic instruments to a console. Connections: Dual and XLR XLR inputs, XRL XLR outputs. Signal handling: accepts unbalanced inputs and provides balanced outputs, and supports balanced-input to balanced-output operation. Each channel includes a common-ground / non-common-ground switch for flexible grounding configuration.
