The black Shure CVB-B/C is a Centraverse Series cardioid boundary condenser microphone designed to provide an optimized-for-speech frequency response and discreet desktop installation for presenters and speakers in conference rooms, corporate events, houses of worship, and meetings. The low-profile microphone features CommShield technology to reject RF interference and an attached 12’ XLR cable for compatibility with most mic preamps.
The cardioid condenser element yields a frequency response of 70 Hz to 16 kHz, which naturally attenuates low frequencies that are often produced by vibration and rumble. It is powered by 11 to 52 VDC phantom power.
- Cardioid polar pattern cartridge
- CommShield technology guards against RF interference from portable wireless devices (smartphones, among others) and enables high resistance to nearby radio signals
- Attached 12\' XLR cable
- Frequency response is suitable for capturing fast transients in a wide variety of locations such as podiums and desktops
- Shure design and rugged, dependable construction
- Mounting holes for secure installation
- CE compliant

The white-finished version of the U851R, the phantom-powered U851RW features a PivotPoint® rotating output connector, UniSteep® filter and UniGuard® RFI-shielding technology. Offering outstanding speech intelligibility and transparent sound quality for surface-mount applications, the U851RW 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 U851RW is equipped with self-contained electronics, eliminating the need for an external power module.
- Designed for surface-mount applications such as high-quality sound reinforcement, professional recording, television, conferencing and other demanding sound pickup situations
- PivotPoint® rotating output connector allows cable to exit from either the rear or the bottom of the microphone
- Superior off-axis rejection for maximum gain before feedback
- UniGuard® RFI-shielding technology offers outstanding rejection of radio frequency interference (RFI)
- Self-contained electronics eliminate need for external power module
- Small-diameter UniPoint® capsule near boundary eliminates phase distortion and delivers clear, high-output performance
- Heavy die-cast case and non-slip silicon foam bottom pads minimize coupling of surface vibration to the microphone
