What is the primary function of the eLumen8 Cygnus SPLIT2?

The primary function is to split a single DMX signal into two separate, isolated outputs. It also boosts the signal to ensure data integrity over long cable runs or across multiple fixtures.

Does this device support RDM?

Yes, the Cygnus SPLIT2 features RDM (Remote Device Management) support. This allows for bi-directional communication between the controller and fixtures for tasks like remote addressing.

How does the isolation feature protect my equipment?

The outputs are electrically isolated, which prevents electrical surges or interference on one DMX branch from travelling back to the controller or affecting the other output branch. This protects sensitive electronics in the event of a fixture failure.

What kind of power supply does the unit require?

The unit operates on a DC input range of 9–24V. A compatible power adaptor is included with the device for ease of use out of the box.

Is the Cygnus SPLIT2 noisy during operation?

No, the device uses convection cooling rather than internal fans. This makes it completely silent, which is ideal for use in quiet environments like theatres or presentation halls.

What material is the chassis made of?

The chassis is constructed from aluminium. This provides a balance between high durability for road use and a lightweight profile for easy transport and mounting.

How can I tell if the signal is working correctly?

The device is equipped with clear LED indicators on the front panel. These allow technicians to verify the presence and status of the DMX signal at a glance during setup or a show.

Can I use this with any DMX-compatible lighting fixture?

Yes, it is compatible with standard DMX512 fixtures, including products from brands like Equinox, Chauvet, and Stagg. It works with moving heads, par cans, and strobes alike.

How many outputs does this splitter provide?

The Cygnus SPLIT2 provides two separate DMX outputs from a single input source. This is suitable for splitting a signal into two different directions on a stage.

Why should I use this instead of a simple DMX Y-cable?

Unlike a Y-cable, the SPLIT2 provides active signal boosting and electrical isolation. Using a passive Y-cable can cause signal reflections and data errors that disrupt the lighting show.

Is this unit suitable for outdoor use?

The product description does not specify an IP rating for outdoor use. It is designed for indoor professional lighting applications and should be protected from moisture.

What is the typical price range for this device?

The eLumen8 Cygnus SPLIT2 typically retails for approximately GBP 138. This makes it a mid-range professional-grade utility for lighting setups.

Overview

The eLumen8 Cygnus SPLIT2 Compact 2-Way DMX Splitter/Booster is a specialist tool for lighting technicians requiring a dependable method for splitting a single DMX data stream into two separate branches. By amplifying and distributing the signal, it ensures that lighting rigs maintain data integrity across multiple fixtures. The device is housed in a robust yet lightweight aluminium chassis, making it suitable for both permanent installations and touring environments where space is at a premium.

Technical Features and RDM

A primary feature of the Cygnus SPLIT2 is its full support for Remote Device Management (RDM). This allows technicians to communicate bi-directionally with compatible fixtures, enabling remote addressing and status monitoring without needing physical access to the lights.

The unit operates on a wide voltage range of 9–24V DC and includes a power adaptor. Its design prioritises reliability through the use of opto-isolation, which protects the main DMX controller from electrical faults or interference that may occur on the output lines. For monitoring, the device features clear LED indicators that provide instant visual feedback on the signal status.

Operational Character

In operation, the SPLIT2 is designed to be 'invisible' within the signal chain, providing clean data transmission without latency. Its convection cooling system ensures silent operation, as there are no internal fans, which is advantageous for noise-sensitive environments like theatres or studios. The compact form factor allows it to be tucked away in trussing or small equipment racks without contributing significant weight to the setup.

Suitability and Integration

This splitter is ideal for small to medium-scale lighting rigs where a single DMX universe needs to be branched to different physical locations, such as stage left and stage right. It is frequently used alongside fixtures such as the Equinox Fusion 120Q LED Moving Head, the Chauvet DJ Sentinel Wash Q7Z, or the Cameo ROOT PAR 4. Technicians using wireless solutions like the Chauvet DJ FlareCON Air 2 may use the SPLIT2 to further distribute signals once they have been converted back to wired DMX.

Comparison to Alternatives

Compared to larger rack-mounted splitters, the Cygnus SPLIT2 offers a more portable and cost-effective solution for rigs requiring fewer outputs. While larger units might offer 4, 6, or 8 outputs, the SPLIT2 focuses on a compact 2-way split. Unlike basic passive Y-splitters, which can cause signal degradation and lack isolation, the SPLIT2 actively boosts the signal and provides electrical protection, making it a safer choice for professional applications involving expensive moving heads like the Stagg Headbanger XT or Eurolite TMH-41.
