Audio-Technica U851R Cardioid Condenser Boundary Microphone

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. PivotPoint® rotating output connector allows cable to exit from either the rear or the bottom of the microphone.
