The JRAUDIO PRO-3MAX is a professional audio ground isolator with XLR connectivity, designed to reduce hum, unwanted noise, and interference caused by ground loops in an audio system. It is inserted between the various devices in a system to isolate the ground connection and limit electrical disturbances that may affect the audio signal. It can be used in configurations combining a computer, audio interface, amplifier, mixing console, or other audio equipment when background noise or interference appears after interconnection. JRAUDIO presents the PRO-3MAX as a professional isolation and noise suppression solution, with a design intended for balanced XLR, RCA, or 6.35mm Jack audio connections.
