Meet THEOS DIFB (Global Unit), a modern, metal-bodied digital IFB receiver built for fast, reliable cueing on set. Its ultra-wideband tuning (550–960 MHz) with Global OneBandTM
awareness adapts to local RF rules, while the true-diversity design with dual SMA antennas locks onto clean signals. A large color screen and metal volume/selector knob make on-body control effortless, and the locking 3.5 mm headphone jack keeps earpieces secure. Works with THEOS transmitters and can scan/pair for rapid deployment.
For productions hopping between channels and crews, THEOS DIFB stores up to 20 frequency presets you can spin through quickly. Battery life is class-leading—up to 17 hours on lithium (approx. 10 hrs alkaline, 9 hrs with 1900 mAh NiMH)—and USB-C lets you power externally for all-day shoots. Text-to-speech in your headphones speaks out the DID name so you always know which feed you’re monitoring, even when the pack is on your belt. Metal body construction is tested for 1-meter drops.
Scale and coordinate fast with Sidus Audio app control: perform RF scans, bulk program your preset banks, and handle frequency coordination from your phone—ideal for multi-device, multi-team days. Bluetooth headphone support and Bluetooth app setup streamline monitoring and setup across departments. If you’re outfitting a team, bundle options are available for cost-effective rollouts.
The THEOS DIFB Kit (Global Unit) ships ready for set life: you get three DIFB receivers, one DBTX transmitter, a C12 cable, a set of cuttable antennas for local tuning, and four beltclips. It’s a complete, coordinated package designed to spin up a professional IFB ecosystem fast—ideal for crews who want reliable cueing for clients, agency, and talent on corporate/commercial video production.
