30Hz-20kHz On/Off HPF 48V Integral PSU Other Capsules
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 is equipped with a PivotPoint® rotating output connector, UniSteep® filter, and UniGuard® RFI-shielding technology. It accepts interchangeable condenser elements – omnidirectional (360°), cardioid (120°), and hypercardioid (100°) – available separately. 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.
Available configurations:
U851Rb: cardioid polar pattern (120° acceptance angle); 25.0' (7.6 m) cable with TA3F connector at the microphone and XLRM output connector; black finish.
U851RWb: cardioid polar pattern (120° acceptance angle); 25.0' (7.6 m) cable with TA3F connector at the microphone and XLRM output connector; white finish.
U851RbO: omnidirectional polar pattern (360° acceptance angle); 25.0' (7.6 m) cable with TA3F connector at the microphone and XLRM output connector; black finish.
Designed for surface-mount applications such as high-quality sound reinforcement, professional recording, television, conferencing and other demanding sound pickup situations
Superior off-axis rejection for maximum gain before feedback
PivotPoint® rotating output connector allows cable to exit from either the rear or the bottom of the microphone
Small-diameter UniPoint® element near boundary eliminates phase distortion and delivers clear, high-output performance
Available interchangeable elements permit angle of acceptance from 100° to 360°
UniGuard® RFI-shielding technology offers outstanding rejection of radio frequency interference (RFI)
Self-contained electronics eliminate need for external power module
Heavy die-cast case and non-slip silicone foam bottom pads minimize coupling of surface vibration to the microphone
Low-profile design with low-reflectance finish for minimum visibility
Threaded inserts on bottom of microphone allow it to be mounted with screws for increased security
