quadETH

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.

Four ports, your way

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.

Art-Net 4 + sACN

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.

RDM built in

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.

Scenes & failover

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.

Power, either way

Run it from PoE — one cable for data and power — or from USB-C. Whatever the install wants.

Screen + web UI

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.
