The white-finished version of the U851R, the phantom-powered U851RW features 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 U851RW 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
