Product Overview
The Audio-Technica U841R is an omnidirectional condenser boundary microphone with a built-in power module, designed for clear, intelligible sound reinforcement, recording, television, and conferencing in surface-mount applications. Its 360-degree pickup captures speech evenly across a table, and UniGuard RFI shielding protects against interference. This professional boundary microphone is built for installed commercial AV.
Product Description
The Audio-Technica U841R places a small-diameter capsule near the boundary to eliminate phase distortion and deliver clear, high-output performance. A heavy die-cast case with silicone foam bottom pads minimizes coupling of surface vibration.

Its low-profile, low-reflectance black finish keeps it discreet on a conference table, and it runs on 11V to 52V phantom power. Explore more Audio-Technica boundary microphones at Creation Networks.
