Audio-Technica U851R
Cardioid Condenser Boundary Microphone (non-power module model)

U851R

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.

Features

• 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 black finish for minimumvisibility
