Shure CVB-B/C Boundary Condenser Microphone Cardioid - Black

The Shure CVB-B/C is a half-cardioid boundary condenser microphone purpose-built for installed sound reinforcement in conference rooms, courtrooms, houses of worship, and lecture halls. Its flat, low-profile housing sits directly on a table or podium surface, using the boundary effect to deliver consistent, phase-coherent audio pickup. The cardioid polar pattern focuses sensitivity toward the talker while attenuating ambient room noise, feedback, and off-axis sound sources — a critical advantage in reverberant or multi-microphone environments.

What sets the CVB-B/C apart from generic boundary microphones is Shure's CommShield Technology, which provides measurable rejection of radio-frequency interference generated by nearby smartphones, two-way radios, and other wireless devices. In boardroom and government settings where participants routinely keep phones on the table, this eliminates the buzzing artifacts that plague unshielded condenser microphones. The attached 12-foot XLR cable and black finish allow for clean, professional installations with minimal visual impact, making the CVB-B/C a set-and-forget solution for permanent AV systems.
