Rack-mount DMX/RDM signal amplifier designed for professional lighting control systems, featuring automatic DMX/RDM signal detection with 1 input and 16 isolated outputs to easily expand the number of connected devices. It amplifies and relays weak signals to extend transmission distance, with a BYPASS function for flexible system expansion. Independent photoelectric isolation between input and outputs enhances system safety and reliability, while Neutrik 3-pin and 5-pin XLR connectors ensure secure connections. Built in a standard 1U rack format, it is ideal for TV studios, stage lighting, and entertainment venues where stable, large-scale DMX distribution is required.
