The Audio Technica U851R and U851RW is a phantom-powered boundary microphone featuring a PivotPoint rotating output connector, UniSteep filter and UniGuard RFI-shielding technology. Offering outstanding speech intelligibility and transparent sound quality for surface-mount applications, the U851RW 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 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
• Available in black (U851R) or white (U851RW)
