OCTO MK3
eDMX to SPI Pixel Controller with Standalone Mode & Overdrive Feature capable of transmitting up to 32 universes of SPI data in a compact 4-module DIN-rail form factor.
Unleash unprecedented power with 32 universe capacity and flexible port configuration
Referred to as the ‘OCTO MK3,’ the OCTO is a powerful quad-output eDMX to LED pixel converter with overdrive mode transmitting up to 32 universes. Robust and reliable, it connects directly to LED lights, elevating architectural, commercial, and entertainment projects. Designed for fast deployment of LED strips and pixel systems, the OCTO MK3 supports Art-Net, sACN, ESP, and KiNet protocols, and works with over 20 industry-standard SPI LED strips. It features flexible output configuration with up to 8 universes per port—2 outputs with Clock support or up to 4 outputs when repurposing Clock as additional data ports. Its localhost web interface enables easy gradient effects via the inbuilt FX engine, with standalone shows on power-up—no DMX needed. With installer-friendly features like Port Sync, network daisy-chaining, custom protocol creation, and flexible mounting options, the OCTO MK3 is the ultimate LED pixel control solution.
