Overview
Deliver dependable, conference-ready audio and secure monitoring with the Audio-Technica U891RB touch-sensitive condenser boundary microphone. Built for professional installations — from boardrooms and courtrooms to control centers and surveillance suites — this boundary microphone offers intuitive capacitive touch control with three operating modes to streamline presentations, conferencing and security monitoring. The cardioid UniPoint element and wide 20 Hz–20 kHz frequency response prioritize speech clarity while rejecting off-axis noise, and the -34 dB sensitivity ensures consistent pickup at typical tabletop distances. UniGuard RFI shielding and an 80 Hz UniSteep low-cut filter reduce radio interference and low-frequency rumble common in IT and security environments. Installation is simple and secure: the PivotPoint rotating output connector, integrated 25' cable and threaded bottom mounts allow discreet surface mounting and flexible cable routing. Self-contained phantom-powered electronics eliminate the need for an external module, and the two-state RGB LED gives instant visual status. Ideal for conferencing, AV integration, security surveillance and remote monitoring — specify the Audio-Technica U891RB for reliable, professional audio capture.
