Deity THEOS DLTX Wireless Microphone Transmitter
The DLTX runs on an ultra-wideband digital UHF spectrum between 550 and 960 MHz, with frequency ranges that swap by firmware update so one transmitter travels rather than getting swapped out region to region. Its digital RF modulation stays intermod-free, avoiding the harmonic buildup that stacks of analog wireless can create on a busy set. A 3-pin LEMO input takes a phantom-powered lavalier at 48V, and an analog limiter catches a spike before the digital link clips it.
An onboard recorder writes 24-bit or 32-bit float WAV to a microSD card up to 512 GB, so a subject's audio is banked even if the RF link drops out. It syncs timecode wirelessly from a Deity TC-1, keeping that backup file aligned with camera in post. Two AA batteries run it up to 14 hours, and a USB-C port covers external power on a longer day. Everything from RF power to input gain is reachable from the Sidus Audio app through a full-color LCD on the CNC-milled aluminum body.
