The DCHT portable digital stereo transmitter is designed for use in film and TV production as both a wireless audio link from a bag or cart system to cameras and as a portable IFB transmitter paired with the Duet digital wireless M2R receiver packs. The DCHT accepts two channels of mic or line level analog signals or an AES digital signal from a mixer and transmits to the receiver or receivers in a purely digital format. The digital architecture of the new DCHT is a third-generation design with specially developed, high-efficiency circuitry for extended operating time on two AA batteries.

The DCHT can tune across the available UHF TV band from 470.00 to 607.950 MHz (470-614 MHz for export versions) in 100 kHz or 25 kHz steps, offering more than 6000 frequencies. The RF output can be set to 10, 25 or 50 mW, thus providing flexibility in terms of operating range for the intended application. The digital architecture allows for AES256-CTR encryption for applications where content security is a concern.
