1U Rack‑Mount DMX512 Splitter,2‑In‑8‑Out,Isolated Outputs,Per‑Channel LED Indicator

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

This 1U 2 In 8 Out Rack‑Mount DMX512 Splitter Amplifier is professional rack‑mount signal‑distribution hardware built for theatre productions, concert touring, permanent venue installations, large‑scale music festivals and professional touring‑rental projects across worldwide markets. As core signal‑processing equipment for complex stage‑lighting systems, this splitter solves ground‑loop interference, signal attenuation and crosstalk‑noise issues in multi‑universe DMX wiring environments for indoor event deployments.

This hardware strictly follows DMX512‑1990 industry protocol and meets CE and UL safety certification requirements. It receives two independent DMX input signals and generates eight fully electrically‑isolated amplified output channels. High‑voltage‑protection circuit protects downstream lighting devices from voltage spikes. Every output channel adopts separate signal‑amplifier circuit and dedicated LED status indicator, allowing field technicians to quickly judge signal working‑state and complete troubleshooting without extra measuring instruments.

The compact lightweight metal chassis follows standard 1U 19‑inch rack‑mount form‑factor, convenient for integration into main control rack systems for fixed venues or touring flight‑rack setups. It supports universal wide‑voltage AC88‑256V power‑input adapting to different national power‑grid standards for 50Hz or 60Hz. All signal ports adopt standard 3‑pin XLR DMX connectors for seamless compatibility with mainstream lighting consoles and stage fixtures.

Physical specification: overall dimension 482 × 118 × 46 mm with net‑weight of 1.35 kg. Each single output channel can drive up to 32 DMX‑compatible lighting fixtures. Users must fit DMX terminator on the last fixture of each output chain for stable signal transmission. The unit must be reliably earthed during operation; cut off mains power before replacing internal fuse.

This device is designed for indoor rack‑installation, not for direct outdoor exposure. Regular visual inspection of connectors is recommended for long‑term continuous‑operation projects.

With dual‑input multi‑output signal amplification, full electrical‑isolation protection, 1U standard rack‑mount mechanical‑design and wide‑range universal‑voltage input, this DMX512 splitter amplifier offers reliable signal‑distribution solutions for rental‑houses, venue‑system integrators and lighting‑design teams across global markets.
