The Swisson XSR-5R is a single rack-mount DMX and RDM signal distribution device with 5 outputs via 5-pin XLR connectors. This professional-grade splitter boosts and regenerates DMX signals while providing optical isolation on each port to prevent ground loops. Featuring a specialized power supply for stable operation under variable mains conditions, it reduces signal reflection issues and includes built-in line termination. The unit supports both standard DMX512 (ANSI E1.11) and RDM (ANSI E1.20) protocols, and offers a 'DMX only' mode that filters non-DMX data. With dimensions of 48.26 x 11.2 x 4.45 cm and weighing 1.5 kg, it's designed for reliable signal distribution in professional lighting systems.
