The Deity THEOS DIFB is a next-generation digital UHF interruptible foldback (IFB) transmitter and companion receiver designed for modern production environments that demand exceptional reliability, wideband flexibility, and professional monitoring features. Whether used for crew cueing, director feeds, script supervision, or continuity playback, the DIFB allows production teams to listen in on any Deity THEOS transmitter in real time with crystal-clear digital audio and minimal latency.

Built on Deity’s Global OneBand™ platform, the DIFB offers an ultra-wide tuning range from 550MHz to 960MHz, allowing it to operate virtually anywhere in the world without swapping hardware or purchasing regional frequency blocks. The unit automatically conforms to local RF regulations using GPS-based location control, ensuring peace of mind when traveling from country to country. With the ability to scan for nearby THEOS transmitters and auto-pair to their signals, the DIFB is a powerful tool for fast deployment on film sets, broadcast stages, and ENG workflows.

The DIFB features dual SMA antenna ports for true diversity reception, dramatically increasing signal stability and reducing dropouts in crowded RF environments. The locking 3.5mm headphone output is designed for production durability, complete with a metal volume knob for tactile adjustment. Text-to-speech channel announcements speak the DID name directly into your headphones so you always know which feed you’re monitoring, even when the device is clipped to your belt or hidden in your pocket.

With up to 17 hours of battery life on a single lithium AA pair and support for USB-C external powering, the DIFB easily outperforms traditional IFB receivers. It can also store up to 20 frequency presets, enabling fast switching between transmitters, scene banks, or backup channels. For wireless management, the Sidus Audio app enables remote bulk configuration, scanning, bank programming, and coordination, allowing sound teams to synchronize multiple units from a smartphone or tablet.

Designed with durability in mind, the DIFB features a CNC-milled metal chassis rated for 1-meter drop protection, making it rugged enough for high-pressure production use. Bluetooth headphone support and app-based setup are available in global models, while a dedicated North American version (branded HUSH Wireless) offers ultra-dense channel spacing and legal compliance for restricted RF zones such as Guard Band, Duplex Gap, and 941MHz.

Whether you are cueing talent on set, monitoring boom feed, providing director IFB, or coordinating multiple wireless systems, the Deity THEOS DIFB delivers a powerful, ultra-flexible monitoring solution built for the realities of modern production.
