Offers outstanding speech intelligibility and transparent sound quality

Featuring breakthrough audio and mechanical design innovations, the phantom-powered U851R offers outstanding speech intelligibility and transparent sound quality for surface-mount applications. The microphone is equipped with a PivotPoint rotating output connector, UniSteep filter and UniGuard RFI-shielding technology. It accepts interchangeable condenser elements—available for boundary microphones in cardioid, hypercardioid and omnidirectional polar patterns. With a heavy die-cast case and silicon foam bottom pads to minimize coupling of surface vibration to the microphone, the U851R is equipped with self-contained electronics, eliminating the need for an external power module.

Audio-Technica U851R Boundary Mic Features:

  • Designed for surface-mount applications such as high-quality sound reinforcement, professional recording, television, and conferencing
    PivotPoint rotating output connector allows cable to exit from either the rear or the bottom of the microphone
    Superior off-axis rejection for maximum gain before feedback
    UniGuard RFI-shielding technology offers outstanding rejection of radio frequency interference (RFI)
    Self-contained electronics eliminate need for external power module
    Small-diameter UniPoint capsule near boundary eliminates phase distortion and delivers clear, high-output performance
    Heavy die-cast case and non-slip silicon foam bottom pads minimize surface vibration to the microphone
    Low-profile design with low-reflectance finish for minimum visibility
