MADRIX STELLA is all about rock-solid performance.


It makes sure that your carefully selected DMX fixtures reliably light up with vivid colors and smooth animations. It syncs across ports and different devices to make sure the lighting always looks amazing.

Controlling 2 DMX universes, you can choose output or input for each port, which directly connect to DMX512.

But that's not all. MADRIX STELLA supports Remote Device Management. It is no longer only about sending out control data. Devices now respond. This enables unprecedented possibilities for remote configuration and monitoring.

While previously unheard of, lighting control with Art-Net and supervision with RDM are even possible at the same time, continuously during live operation.

The MADRIX STELLA is a dedicated control interface for DMX512 and Art-Net or Streaming ACN that is designed for high quality and practicability in permanent LED installations.


Art-Net / Streaming ACN / USB
Art-Net or Streaming ACN data is directly converted to DMX512. Optimize and decentralize cabling to cover any distance to the device using Ethernet network. In addition, simply connect to MADRIX 5 over USB.

Directly connect DMX512 to the two 3-pin screw terminals to distribute 2 DMX universes per unit as input and/or output, eliminating the need for XLR connectors as a result. Simply use several units at the same time for larger projects.


Easy Configuration
MADRIX STELLA offers powerful features. Managing the device is still quick and easy. Supply power over USB or 5 V to 24 V over a 2-pin screw terminal.

Sync Mode
MADRIX 5 and MADRIX hardware allow you to fully synchronize Art-Net data for all output ports and across multiple devices to get an optimal image on the LEDs without visual interruptions.


3rd-Party Controllers
MADRIX STELLA complies with official protocol specifications and can be used as a regular node with your other consoles, controllers, or software solutions.

RDM & Daisy-Chain Support
2 Ethernet ports allow for separate network connections as well as linearly daisy-chaining several devices together. On top, the device supports the Remote Device Management standard.


Designed For DIN Rails Or Walls
Its non-conductive enclosure and standardized design for 35 mm top-hat rails make mounting quick, easy, and safe. 2 extra brackets are provided for optional wall mounting. 9 indicators quickly show the device status with the option to turn them off.

Invaluable Features
The device is ready within seconds after startup. HTP merging is automatically available for two Ethernet sources. Its firmware is upgradable. Access and change specific device settings using the built-in web configuration page.




Seamless Integration Of Art-Net & RDM
RDM is fully supported over Art-Net, including ArtRdm, all other required packets, and full and continued discovery of RDM devices.

Use MADRIX STELLA and MADRIX RADAR together for additional benefits:
1) All RDM devices/sub-devices connected to STELLA are automatically unlocked in the RADAR Software for free,
2) With RADAR, the complete RDM specifications of ANSI E1.20 and ANSI E1.37-1 are available to you over Art-Net,
3) Thanks to STELLA's Packet Multitasking, RDM and Art-Net can be sent and received at the same time and during live operation.
