RTctrl 1U USB-C CRMX Transmitter
Built on the LumenRadio TimoTwo chip with Cognitive Coexistence, the RTctrl 1U turns any USB-C-equipped iPad, Mac, or Windows PC into a professional CRMX wireless DMX transmitter. One cable carries power and data. Art-Net 4 and sACN merge simultaneously (HTP/LTP), dual XLR-5 ports mirror CRMX output or accept console DMX input, a color TFT display shows live status, and a built-in 512-channel web console lets you run a show from any browser. Compatible with Aputure, ARRI, Astera, Nanlux, Creamsource, Godox, RC4, and 250+ fixture brands.
