Audio Technica U851R Cardioid Condenser Boundary Microphone Details
The Audio Technica U851R Cardioid Condenser Boundary Features breakthrough audio and mechanical design innovations. The phantom-powered Audio Technica U851R Cardioid Condenser Boundary 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 Audio Technica U851R Cardioid Condenser Boundary is equipped with self-contained electronics, eliminating the need for an external power module.
