CA8402P is a DMX512 splitter amplifier featuring 1 optically isolated DMX input and 4 DMX outputs, plus 4 AC PowerCON outlets. It distributes DMX control and mains power from a single compact metal chassis, reducing cable clutter for tours, rentals and fixed installations. Port-level protection (overcurrent, overvoltage, ESD) and robust line drivers enable stable transmission over long runs while minimizing interference and ground loops. Wall/truss mounting is supported.
