The Deity THEOS DIFB is a compact, metal-body IFB receiver built for film and television crews who need reliable, low-friction audio monitoring on set. With dual removable antennas for robust reception, a bright screen, and simple front-panel controls, it's designed to keep directors, clients, and script supervisors connected to the feed without slowing down the shoot. Pop it on a belt, plug in your headphones, and you're ready to monitor. Beyond the basics, the DIFB adds modern conveniences that streamline daily use. You get fast auto-scanning to find clean frequencies, a "bank" library to save favorites, and a voice reminder option that can speak frequency changes so you can keep your eyes on set. Power comes from two AA batteries, with selectable battery profiles for accurate runtime readouts. There's a standard 3.5 mm output for wired headphones plus built-in Bluetooth so you can pair supported wireless headphones when cables would get in the way. Firmware updates and app control (via Sidus Audio) round out a receiver that's easy to configure and hard to rattle.
