1U Rack‑Mount 1‑In‑8‑Out DMX512 Splitter Amplifier,Galvanic Isolation For Fixed Venue & Rental Systems

Professional DMX Signal Amplifier,AC88‑256V Wide‑Voltage,3‑Pin/5‑Pin XLR for Stage Lighting

This 1U 1‑In‑8‑Out rack‑mount DMX512 splitter amplifier is standard 19‑inch rack‑mount signal‑distribution hardware built for fixed venue control‑rooms, theatre installations, touring flight‑racks and touring‑rental deployments across global markets. Compliant with DMX512‑1990 standard. It accepts one DMX input and provides eight electrically‑isolated amplified outputs with high‑voltage protection and practical built‑in terminator switch. Each channel features independent amplifier and dual DATA+/DATA‑ LED status indicators. 3‑pin XLR comes as standard with 5‑pin XLR available on request, supporting wide‑range AC88‑256V 50‑60Hz mains supply, trusted by venue technicians and worldwide rental crews.

Fixed‑installation venues and touring rack systems impose unique demands on DMX signal processing hardware. Unlike portable hang‑on splitters designed for temporary truss mounting, rack‑mount DMX distribution hardware must integrate neatly within crowded 19‑inch control racks, simplify cascade wiring, and reduce the number of loose external terminator adapters that are easily lost on busy event sites. This 1U DMX512 splitter addresses these real‑world pain‑points for integrators and rental stock managers.

Built strictly to DMX512‑1990 industry standard, the unit converts one incoming DMX control signal into eight fully electrically‑isolated amplified output paths. Every output channel uses its own independent driver circuit, with full galvanic separation covering signal ground lines. This stops ground‑loop hum, signal drift and unexpected fixture resets that frequently occur when mixing multiple pieces of stage equipment with differing ground potentials inside large venue rigs. Distinct dual DATA+ and DATA‑ LED indicators per channel give technicians instant visibility of signal activity without test tools.

A key practical upgrade is the integrated hardware terminator switch. In multi‑unit cascaded DMX setups, installers no longer need to keep track of separate 120‑ohm terminator plugs. Users simply toggle the physical switch ON for the final splitter within the signal chain. This greatly lowers human error risk during fast venue load‑ins, a very common source of intermittent lighting glitches.

Form‑factored as standard 1U height for 19‑inch racks, chassis dimensions are 482×147×72 mm with net weight of 1.9kg. It fits seamlessly into permanent theatre control racks as well as shock‑resistant touring flight‑racks. Universal AC88‑256V wide‑voltage power input covers 50Hz and 60Hz mains across nearly all global regions. Hardware ships with 3‑pin XLR connectors; projects requiring 5‑pin XLR can place custom orders.

Each individual output channel supports a maximum load of 32 DMX‑compliant lighting fixtures. Even with the internal terminator switch, users still must observe per‑port fixture limits. Reliable protective earthing is mandatory for safe operation; always disconnect mains power before replacing the internal fuse. The unit is engineered exclusively for indoor rack‑mount deployment and must stay protected against moisture exposure.

For system integrators building permanent theatre, house‑of‑worship and broadcast installations, alongside rental companies maintaining standardized flight‑rack inventories, this rack‑mount DMX splitter delivers streamlined signal management. Its built‑in termination, channel‑specific diagnostic LEDs and robust isolation cut down troubleshooting time and improve overall system stability for every live production.
