All Theos Digital Wireless features

Wideband UHF Spectrum

One of the standout features of the Deity Theos Digital Wireless Microphone System is its use of a wideband UHF spectrum rather than the crowded 2.4Ghz band. Frequencies span between 550-960 MHz.*

Theos Digital Wireless also features swappable frequency ranges based on your phone’s GPS / Firmware Update. Now you can travel the world with one wireless microphone kit.

*Actual spectrum is limited by local laws. See your government's rules on RF spectrum for wireless microphones -

Built-in Recorder

The Deity Theos Digital Wireless Microphone System also features a transmitter with a built-in recorder. The onboard recorder features both 24-bit and 32-bit float formats so you never have to worry about gain staging on your backup WAV files. Recordings are saved to a Micro SD card, up to 128Gb in size, providing ample space for your audio recordings.

The built-in recorder features an impressive EIN self-noise of -130dBu (A-weighting, gain at +30dB, 150ohm source impedance). This puts it on par with some of the most expensive audio recorders in the film industry.

Wireless Timecode Sync

The Theos’ most unique feature is that the transmitter can be natively synced wirelessly from the Deity TC-1 timecode generator. Timecode ensures your backup WAV files will sync with your master file in post. This feature is especially useful for filmmakers who need to work with multiple cameras or devices. It ensures that your audio and video files are perfectly synced, thus making the editing process much smoother. Alternatively, the DBTX can be synced via the 3.5mm jack if you are using 3rd party timecode generators.

Full Color LCD Screen

One of the standout features of the Theos Wireless System is its full-color LCD screen, which displays the status of the device. This screen makes it easy to monitor the system's performance, ensuring that you always have a clear view of your audio levels, battery life, and other critical information. This feature is especially useful for filmmakers who need to work in various locations and lighting conditions.

CNC Milled Aluminum Body

Both the DBTX and D2RX are made out of 2 blocks of CNC milled Aluminum. The result is a transmitter that only weighs 100 grams (3.5 oz.)

SMA Antenna Ports

Both the DBTX and D2RX come with SMA antenna ports, which allow you to swap out antennas to fine-tune your frequency or replace them if they get damaged. This feature makes transporting your gear more compact in its case, which is especially useful when working on location.

Up To 14Hrs of Battery Life

Theos Digital Wireless is capable of getting up to 14Hrs* of battery life when paired with the 3000mAh Deity AA battery.

The D2RX and DBTX are able to be externally powered via their USB-C ports.

DBTX Battery Life

You can expect to get a full day out of your transmitter when running NiMH rechargeables in your transmitter, at max settings.

D2RX Battery Life

The D2RX will run for nearly 7hrs using rechargeable AA batteries. This makes running the D2RX super affordable for daily use.

Remote Control via Sidus Audio App

The app allows you to perform frequency scanning and frequency assignment, frequency coordination between multiple receivers, gain staging, and remote triggering of the backup recorder. This means you can make adjustments to your audio settings without having to physically touch the device, making it easier to work with when you're on set.

The remote control feature is especially useful for filmmakers who need to work with multiple devices or those who need to make adjustments to their audio settings quickly. It saves time, and it ensures that you never miss a critical moment on set.
