Description

The THEOS DIFB Wireless In-Ear Monitor Receiver is a pro-grade monitoring solution designed for modern stage, studio, and broadcast environments. As part of the THEOS Digital Wireless IEM System, this compact receiver delivers ultra-low latency, crystal-clear audio, and rock-solid wireless performance, making it ideal for musicians, performers, and audio professionals who demand clarity, consistency, and control on stage.

Built around a true digital diversity architecture, the DIFB Receiver ensures stable RF performance across its wide 470–607.5 MHz tuning range (regional variants apply). With a proprietary digital modulation and channel bandwidth of 8 MHz, it achieves a latency of under 1.9 ms which is virtually imperceptible to performers. The intuitive OLED display and rotary encoder with push-button control give users quick access to critical settings like stereo/mono modes, limiter engagement, and output levels, all while monitoring battery, RF, and audio status in real time.

Designed for durability and comfort, the receiver features a metal chassis with rubberized edges, a recessed display for added protection, and a secure integrated metal belt clip. It runs on a removable, rechargeable Li-ion battery, offering up to 7 hours of runtime, and charges easily via USB-C or an external charger which makes it tour-ready and easy to manage.

With its wide frequency response (20 Hz – 20 kHz), ≥106 dB dynamic range, and low <0.05% THD+N, the THEOS DIFB Receiver provides high-fidelity monitoring in even the most demanding environments. Whether you're navigating crowded RF spaces or setting up a personalized monitor mix, this receiver delivers the performance and flexibility professionals rely on.
