DEITY DBTX THEOS D-UHF Bodypack Transmitter (US)

The DEITY DBTX is a compact, professional bodypack transmitter in the THEOS digital UHF ecosystem. Built for production and ENG workflows, the DBTX provides wideband UHF coverage, an onboard backup recorder (microSD), remote control via the Sidus Audio app, and flexible RF power options for robust field performance.

Housed in a CNC-machined aluminum chassis, the DBTX accepts a 3.5 mm lavalier input and supports multiple mic powering modes. The unit offers selectable RF output power, swappable SMA antennas, and a color display for easy setup on set or location shoots.

Designed for run-and-gun production, interviews, and multi-talent shoots, the DBTX delivers reliable wireless audio with backup recording and timecode sync features to help simplify capture and post-production workflows.
