Audio-Technica U851RB Cardioid Boundary Microphone<\/strong> is a phantom-powered condenser boundary microphone designed for surface-mount applications such as high-quality sound reinforcement, professional recording, television, and conferencing. This cardioid boundary microphone is built for outstanding speech intelligibility and transparent sound quality in demanding sound pickup situations.<\/p>\n

The U851RB conference boundary microphone is equipped with a PivotPoint® rotating output connector for flexible cable routing, a UniSteep® filter to help reduce low-frequency noise, and UniGuard® RFI-shielding technology to reduce radio frequency interference. It also accepts interchangeable condenser elements (sold separately), allowing different polar patterns to suit different room layouts and pickup needs.<\/p>\n

Designed for reliable installation, the microphone features a heavy die-cast case and silicon foam bottom pads to minimize coupling of surface vibration. Its self-contained electronics eliminate the need for an external power module, and threaded inserts on the bottom allow secure screw mounting for increased security.<\/p>\n
