    Audio Technica U851R Condenser Boundary Microphone Product Description

    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.


    - Designed for surface-mount applications such as high-quality sound reinforcement, professional recording, television, conferencing and other demanding sound pickup situations
    - 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(R) capsule near boundary eliminates phase distortion and delivers clear, high-output performance
    - Heavy die-cast case and non-slip silicon foam bottom pads minimize coupling of surface vibration to the microphone
    - Low-profile design with low-reflectance finish for minimum visibility
