Audio-Technica U851RO Omnidirectional boundary mic

Featuring breakthrough audio and mechanical design innovations, the phantom-powered U851RO offers outstanding speech intelligibility and transparent sound quality for surface-mount applications. The omnidirectional microphone is equipped with a PivotPoint® rotating output connector, UniSteep® filter and UniGuard® RFI-shielding technology. It accepts interchangeable condenser elements in cardioid and hypercardioid polar patterns. With a heavy die-cast case and silicon foam bottom pads to minimize coupling of surface vibration to the microphone, the U851RO is equipped with self-contained electronics, eliminating the need for an external power module.
