At a Glance

The phantom-powered U851Rb 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 has a PivotPoint® rotating output connector, UniSteep® filter, and UniGuard® RFI-shielding technology. It accepts interchangeable condenser elements – omnidirectional (360°), cardioid (120°), and hyper-cardioid (100°) – available separately. With a heavy die-cast case and silicon foam bottom pads to minimize the 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.
