Cardioid Condenser Boundary Microphone

Description

The phantom-powered U851Rb cardioid condenser boundary microphone offers outstanding speech intelligibility and transparent sound quality for surface-mount applications such as high-quality sound reinforcement, professional recording, television, conferencing and other demanding sound pickup situations. The microphone is equipped with a PivotPoint rotating output connector, UniSteep filter and UniGuard RFI-shielding technology. It accepts interchangeable condenser elements, available separately in 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 U851Rb is equipped with self-contained electronics, eliminating the need for an external power module. Threaded inserts on the bottom of the microphone allow it to be mounted with screws for increased security.
