The D4 digital 4-channel wireless system was designed as a special purpose system for location production in film and television.

A typical application for this system is in television production as part of what is commonly called a "bag system." A portable mixer and several wireless microphone receivers are carried in an over-shoulder carrying case. The D4T transmitter is connected to the outputs of the mixer to transmit up to four audio channels to one or more D4R receivers mounted on video cameras.
