D-Fi Hub is a compact, easy-to-use DMX unit that functions as either a transmitter or receiver. For more stable communication between units, it operates on a 2.4 GHz frequency range and includes an “auto” function which automatically finds the best frequency and syncs the units effortlessly. You can wirelessly synchronize an unlimited number of D-Fi-ready fixtures simultaneously, and operate them using the simple navigation on the OLED digital display.
