In development
Four DMX universes from one Ethernet drop. The four-port successor to dualETH — every port independently in or out, with Art-Net 4, sACN and full RDM. Built in the UK.
Coming soon · not yet on sale
One Ethernet cable to a small metal box; four DMX universes out the other side. quadETH takes Art-Net or sACN off your lighting network and drives up to four independent DMX lines — or turns any port around to read a desk and republish it onto the network. It's the node for when two ports (dualETH) isn't enough.
Each of the four 3-pin XLR ports is set independently to DMX-out or DMX-in, on any Art-Net or sACN universe. In and out on the same box.
Full Art-Net 4 receive with remote configuration (DMX Workshop and friends), and sACN E1.31 with priority handling — selectable per port. HTP/LTP merging when two sources collide.
Discover fixtures on a port and set their address, mode, identify and labels straight from the web UI or over Art-Net. quadETH answers RDM too, so controllers can find and identify it.
Non-volatile memory that survives a power cut: hold-last-value failover so a network drop isn't a blackout on stage, plus saveable scene snapshots you can recall from the browser.
Run it from PoE — one cable for data and power — or from USB-C. Whatever the install wants.
An on-board OLED shows the IP and per-port status at a glance, and the self-contained web interface handles everything else — no app, no cloud. mDNS means several units coexist on one LAN.

If two ports cover your show, dualETH is the lighter, cheaper choice — and it's shipping today (it does RDM too, on port A). quadETH is for when you need four ports, RDM on every one of them, or scene memory.
quadETH is open for pre-order at £149.99 — a launch price that rises to £199.99 at full release. Reserve a unit from the first production run; shipping Q3 2026.
