1U Rack‑Mount 1‑In 8‑Out RDM‑DMX Distributor,Switchable RDM Filter for Stage Lighting

Professional 8‑Port RDM‑DMX Signal Amplifier,Per‑Channel LED Indicator for Theatre Shows

This 1u rack mount 1 input 8 output switchable rdm dmx512 distributor is 19‑inch 1U rack‑mount bi‑directional RDM‑DMX512 signal‑splitting hardware built for theatre productions, live‑concert tours, TV broadcast‑recording studios and permanent venue‑lighting installations across Europe and North America. This signal‑amplifying unit expands one incoming lighting‑control signal into eight isolated output branches, supporting both standard DMX512 and bidirectional RDM remote‑device‑management workflow for professional venue‑system integrators.

This distributor adopts independent dedicated RDM input and DMX512 input interfaces. Hardware DIP‑switches allow operators to freely toggle each output channel between RDM‑enabled mode and RDM‑filter‑off mode. When RDM function is activated, bidirectional data transfer is available for remote fixture addressing, parameter configuration and device status reading. When RDM filter mode is selected, RDM data gets suppressed, which improves compatibility with older lighting fixtures that cannot process RDM packets.

All signal ports use Neutrik XLR connectors, with 3‑pin as standard and 5‑pin XLR as optional variant. Every input‑output path keeps fully independent signal routing and is fitted with high‑voltage surge‑protection to resist voltage spikes from complex venue power environments. Dedicated LED indicators are assigned for each channel: one indicator shows whether RDM function is activated, another monitors real‑time presence of DMX‑RDM signal, helping technicians quickly inspect signal health status on‑site.

Compact 1U‑height mechanical form factor fits standard 19‑inch equipment racks. Wide‑range AC88‑256V 50‑60Hz power input adapts to diverse mains‑grid specifications throughout European nations and United States. This hardware meets CE, UL and GB 7000.15‑2000 safety‑related specifications. Physical dimension measures 482 mm × 173 mm × 46 mm and net‑weight reaches 1.7 kilograms.

This indoor‑only rack‑mount device must be properly earthed during installation and kept away from moisture and strong magnetic‑field interference. Each output port supports maximum 32 lighting receivers; users must install DMX terminator resistor at the end of each daisy‑chain signal line. Featuring switchable RDM filter, independent signal‑paths and surge‑protected Neutrik connectors, this 1‑in‑8‑out distributor delivers flexible and reliable signal‑distribution solution for complex entertainment‑lighting projects throughout Europe and North America.
