Splitter Pro

Rack-Mountable Signal Management and Amplification Unit

Name: Splitter Pro
Brand: Sundrax

Dual-zone rack mountable professional, optically isolated DMX512 splitter / booster with RDM functionality

The 1U rack DMX splitter distributes the signal from 1 or 2 inputs to 5, 8, or 10 outputs.
In DUO mode, it operates as two independent devices. It supports Input Backup for signal redundancy and Thru DMX for extended patching. Connectors: XLR3/XLR5 or EtherCON. Intelligent indication of DMX512 or RDM data in the channel. Button-free Studio live DMX splitter for indoor use at positive temperatures.

Rack mount DMX booster / splitter housing features

The 1U 19-inch rack-mount splitter measures 482.6 (L) x 43.6 (H) x 125.6 (W) mm and weighs 1.2 kg, allowing multiple devices to be installed compactly. It can also be used as a tour-ready DMX splitter that is easy to transport;
The professional rack DMX splitter has a metal enclosure rated IP44. This provides protection against splashes and solid objects larger than 1.0 mm, reducing the risk of accidental equipment damage;
The operating range is from 0 to +60°C (32°F to 140°F) and up to 95% relative humidity, enabling the splitter to be used almost without restrictions—just avoid extreme conditions and negative temperatures;
The rack-mount 1U DMX booster is installed with the included mounting hardware. It can also be fixed to a truss using a clamp and an additional safety cable;
Screen printing on the housing ensures permanent, clear labeling for the entire service life;
The metal fanless rack DMX booster has no buttons, making it resistant to physical impact.

Inputs, outputs, and connectors
Splitter Pro is a product family that offers 9 modifications. You can choose the configuration of a DMX splitter 5 output or DMX splitter 10 output depending on the needs of your project. The DMX splitter 2 in 8 out supports two modes: Single mode (1 input to 8 outputs) and DUO mode (2 independent inputs, each with 4 outputs). Switching between modes occurs automatically when a DMX cable is connected to the corresponding input. The unit is available with 3-pin or 5-pin XLR connectors, or EtherCON. Using EtherCON optimizes permanent rack DMX installations, as it allows the use of standard, inexpensive UTP cable.

- Power supply via PowerCON ensures a reliable and durable connection;
- The splitter withstands voltages up to 305 V, guaranteeing stability when running from a generator or in networks with unstable power;
- Each port has galvanic isolation, protecting connected devices from electrical interference;
- High-output DMX splitter optimized for working with large numbers of fixtures;
- Intelligent indication for DMX inputs using the RDM protocol simplifies detection of errors and malfunctions in the lighting setup;
- A toggle switch on the housing allows RDM filtering, improving compatibility with different device types;
- The DMX Thru splitter allows DMX signal daisy-chaining.
Target audiences

The touring rental DMX splitter is intended for fixed installations, rental companies, and businesses specializing in stage and event lighting, as well as distributors and resellers of professional audio and lighting equipment.
Application scenarios
- Television studios;
- Concert halls and nightclubs;
- Theatrical FOH racks with permanent installation;
- Architectural lighting control systems and permanent museum illumination.
Problems solved by Splitter Pro
- Need for redundancy and uninterrupted shows → backup input and DMX Thru;
- Large installations requiring multiple outputs → multiple output DMX splitter (5/8/10) options tailored to your project;
- Connector incompatibility → connector flexibility with XLR or EtherCON options. EtherCON DMX racks optimize permanent rack connections;
- Lack of feedback or interference from RDM → splitter supports RDM protocol with dynamic indication and switchable filtering;
- Unstable power supply → withstands up to 305 V, with galvanic port isolation and PowerCON.
Examples of use

Splitter Pro is one of our most popular products, used in theaters, museums, TV studios, as well as for advanced lighting setups at festivals, sports events, and architectural illumination of temple complexes worldwide. This touring rental DMX splitter has established itself as a top-level solution.

Some examples of Splitter Pro applications:
- Gloucestershire College, United Kingdom – synchronizing lighting with music and live stage action across 96 control channels. The splitter’s flexibility and easy setup make it highly effective even with frequent changes in event formats;
- Van Gogh Museum, Netherlands – a dual-zone DMX splitter 8 way controls lighting in different museum sections independently, enabling varied lighting scenarios and creating harmonious accents for exhibits and installations;
- Grange Festival, Hampshire, UK – a professional rack splitter in a permanent lighting control system ensures high-quality opera productions with zero tolerance for technical failures;
- Presidential Palace, Abu Dhabi, UAE – in this architectural lighting project, the DMX splitter 8 channel demonstrated high reliability thanks to optical isolation and RDM support. Flexible control and remote diagnostics were critical for large-scale permanent installations;
- Tokyo Olympics, 12 venues, Japan – fail-safe signal distribution across multiple sites, including the Ariake Gymnastics Centre and Ariake Arena.
