The Deity THEOS DIFB TX is a next-generation wireless in-ear monitor and IFB (Interruptible Foldback) transmitter, designed to meet the needs of professional filmmakers, broadcasters, and audio teams working in dynamic and demanding environments. Built for seamless integration within the THEOS digital wireless ecosystem, this transmitter combines ultra-wideband flexibility, remote setup capabilities, and robust audio performance in a compact, rugged form. With a frequency range spanning 550 MHz to 960 MHz, the DIFB TX supports Global OneBand™ technology, allowing it to adapt to local RF regulations using GPS-assisted region detection. This enables production teams to work across borders with minimal configuration. The proprietary digital modulation ensures clean, 24-bit audio transmission at a 48 kHz sample rate, while the 700 kHz channel spacing helps maximize spectrum efficiency even in crowded RF environments. The metal chassis is drop-tested for durability, and user-friendly ergonomics include a metal headphone volume knob, locking 3.5mm output, and a large color display controlled via a rotary encoder with push-to-select functionality. The device supports up to 20 frequency presets, which can be cycled through quickly during production. Unique to the system is Text-to-Speech DID readout, the transmitter can announce its assigned channel name or number through connected headphones, making channel identification simple even without looking at the screen. Powering the DIFB TX is a high-efficiency battery system that supports up to 17 hours of runtime on a lithium battery, with backup options including alkaline and NiMH. Charging and powering the unit is possible via USB-C, allowing for continuous use during longer shoots or remote applications. Remote configuration is streamlined with Bluetooth support via the Sidus Audio App, enabling wireless scanning, syncing, and bulk management which is a time-saver for teams working with multiple units across large sets. Whether used standalone or as part of a multi-channel setup, the THEOS DIFB TX delivers reliable, flexible wireless audio transmission with intuitive control and rock-solid performance.
