1U Rack‑Mount 2‑In 8‑Out DMX Distributor,Per‑Port A/B Signal Select for Stage Lighting

Dual‑Source DMX Splitter,Independent Signal Path,AC88‑256V for Theatre & Rental Projects

This 1u rack mount 2 input 8 output selectable dmx rdm distributor is 19‑inch 1U rack‑mount DMX‑512 and RDM signal‑routing hardware built for theatre productions, large‑scale live‑concert tours, TV broadcast‑recording studios and mobile event‑rental projects across Europe and North America. This signal‑distribution hardware accepts two completely independent DMX‑RDM source inputs and routes signals to eight output ports. The outstanding feature is per‑channel source selection, letting technicians assign each output channel to pull signal from either source‑A or source‑B individually for flexible complex lighting‑rig layout.

All input‑output signal paths maintain full electrical isolation to suppress ground‑loop noise and cross‑interference. Every Neutrik XLR signal port (3‑pin standard,5‑pin optional) integrates high‑voltage protection circuitry to defend against transient‑voltage spikes from unstable venue power environments. Each output channel is equipped with dedicated LED indicators, clearly showing which signal source is selected and whether valid DMX‑RDM signal is present, simplifying on‑site inspection and fault‑diagnosis work. Channel‑source assignment is configured via front‑panel DIP‑switches.

This compact 1U‑height unit fits standard 19‑inch equipment racks for fixed venue system integration. Wide‑range AC88‑256V 50‑60Hz power input adapts to diverse mains‑grid specifications throughout European nations and United States. The unit complies with CE, UL and GB 7000.15‑2000 safety‑related standards. Physical dimension measures 482 mm × 173 mm × 46 mm and net‑weight is 1.7 kilograms. An internal fuse offers extra hardware‑level power‑circuit safeguard.

This is indoor‑only rack‑mount equipment and must be properly earthed during installation. Operators shall follow DMX wiring best‑practices: install DMX terminator on the last fixture of each output daisy‑chain; do not connect more than 32 lighting fixtures per single output channel. Avoid exposing the unit to moisture and strong magnetic‑field disturbance.

Featuring dual‑source inputs, per‑port independent signal‑source switching, full‑path isolation and surge‑resistant ports, this rack‑mount DMX‑RDM signal distributor delivers flexible signal‑routing solution for complex multi‑source entertainment‑lighting projects throughout Europe and North America.
