Deity Theos UHF Band Features Universal Band: 550-960 MHz for potential frequencies Transmitter has a built-in recorder* for alternative use True 32-bit float multi-analog-digital converter Supports MicroSD card; up to 128GB Wirelessly sync timecode with Deity TC-1; wired via 3.5mm port Supports remote control function via Sidus Audio app Extremely long battery life 100mW RF power; up to 450ft range Wideband UHF spectrum The Deity Theos digital wireless microphone system features a wide UHF frequency band instead of the crowded 2.4 GHz band. The frequencies of this system range from 550 to 960 MHz. (The actual band size and frequency range vary depending on the selected region/group). Wireless Timecode Sync The Theos camera features a unique feature: the ability to wirelessly sync the transmitter with the Deity TC-1 timecode generator. Timecode ensures that backup WAV files are synced with the main file in post-production. This feature is extremely useful for filmmakers working with multiple cameras or devices, as it ensures that audio and video files are precisely synced, greatly simplifying the editing process. The DBTX can also be synced via the 3.5mm port if external timecode generators are used. Remote Control via Sidus Audio App The Deity Theos digital wireless microphone system features a unique feature that allows remote control of the transmitter and receiver via the Sidus Audio app. With this app, you can easily scan and assign frequencies, coordinate frequencies between multiple receivers, adjust audio levels, and remotely operate the backup audio recorder. This feature eliminates the need to physically handle the device, making it more convenient while working on set. SMA Antenna Ports Both the DBTX and D2RX are equipped with SMA antenna ports, allowing you to replace antennas for fine-tuning frequencies or to replace them if they are damaged. This feature makes transporting equipment more convenient in its bag, which is very useful when working on outdoor locations.
