Deity DBTX THEOS Transmitter

A 32-bit float recorder sits inside the Deity DBTX, a THEOS bodypack transmitter that sends digital UHF wireless from 550 to 960 MHz to the D2RX receiver.

The recorder writes 24-bit or true multi-ADC 32-bit float WAV files to a microSD card of up to 128 GB, as a backup or for places where wireless cannot be used. Its self-noise (EIN) is -130 dBu. Units sold or operated in the U.S. cannot transmit and record at the same time.

The DBTX takes timecode wirelessly from a Deity TC-1, or from any generator through a hardwired jam on its 3.5mm jack, so its recordings line up with camera footage in post. Its clock holds 0.15 ppm, one frame in 72 hours.

RF power switches between 10, 25, 50, and 100 mW. From the Sidus Audio app, the user sets gain staging, low cut filters, and remote start of the recorder without handling the transmitter. The SMA antenna port takes the included UHF-TA antennas, which are cut to length for the band in use.

Two blocks of CNC-milled aluminum make a body of 100 g (3.5 oz). Set to 10 mW with the screen and recorder off, the DBTX runs up to 14 hours on Deity lithium AA batteries and up to 8.5 hours on NiMH cells. It also runs from USB-C power. Its 3.5mm TRS input takes the included W.Lav Pro lavalier and offers 3 V or 5 V mic power or line level.
