Chauvet DJ D-Fi USB 2 X4 Wireless DMX Transceiver 4-Pack

D-Fi USB 2 is the second version of Chauvet's stick-it-in-the-port wireless DMX transceiver, and this is the four-pack - typically a transmitter at the desk and three receivers out on the floor. It draws its 5 volts from the host fixture's USB port, so there is nothing to plug in, nothing to charge, and nothing extra to lose in a case.

The rework is mostly about setup speed: LED indicators now show the selected channel directly instead of leaving you counting, and the single-material plastic housing is friendlier to the 2.4 GHz signal than the old shell. Range is 165 feet unobstructed on 2.412 to 2.484 GHz, and each unit acts as either transmitter or receiver. Four transceivers and a quick reference guide are in the box.
