DMX vs Art-Net vs sACN: Which Protocol Should You Use in 2026?

The Three Lighting Protocols

If you're setting up automated lighting for DJ events, you'll encounter three protocols: DMX512, Art-Net, and sACN (E1.31). Each has different strengths, and the right choice depends on your setup.

DMX512 — The Original

DMX512 is the granddaddy of lighting control. It's a serial protocol that runs over 5-pin XLR cables.

Pros: Universal support, simple cabling, proven reliability Cons: Limited to 512 channels per universe, requires physical cables, no networking

Best for: Small setups with fewer than ~30 fixtures in a single chain.

Art-Net — DMX Over IP

Art-Net sends DMX data over standard Ethernet networks. Multiple universes on one cable.

Pros: Multi-universe over Ethernet, widely supported, GrandMA native Cons: Uses broadcast/unicast UDP, can congest busy networks

Best for: Professional setups with multiple universes and GrandMA consoles.

sACN (E1.31) — The Modern Standard

sACN is the ANSI standard for streaming DMX data over IP. Uses multicast for efficient delivery.

Pros: Multicast (efficient), standards-based, priority levels for merging Cons: Slightly less universal than Art-Net in older equipment

Best for: Large-scale installations, touring rigs, and setups where multiple controllers need to merge.

Which Should You Use?

Using All Three with CueSync

CueSync includes experimental (beta) Art-Net and sACN DMX-over-IP output in every edition — including the DJ Edition. You can output to multiple protocols simultaneously, so if your GrandMA3 expects Art-Net but your LED walls use sACN, CueSync handles both from a single configuration.

The DJ Edition supports up to 4 universes (Art-Net or sACN). Theatre and Production editions are unlimited.

Download CueSync free and configure your protocol setup in the routing editor. See also: automating lighting with GrandMA3, the Art-Net + sACN integration page, and pricing.
