Crown MB3 Miniature supercardioid boundary microphone

MB3 Miniature supercardioid boundary microphone, Crown Microphones

The Crown MB3 is a miniature boundary microphone for multi-miking applications such as teleconferencing, distance learning, boardrooms, courtrooms, and security applications. This low-profile, circular mic permanently installs into a hole drilled in a table, lectern, or ceiling.

Thanks to its supercardioid pickup pattern, the MB3 greatly reduces ambient noise and pickup of room reverberation. The result is a clearer, more intelligible sound.

On the bottom of the mic is a tubular power module with a 3-pin XLR-type output connector. It is powered by 12-48V phantom power, and has a low-impedance balanced mic-level output.


  • Ideal for teleconferencing, distance learning, boardrooms, courtrooms and security
  • Small and inconspicuous
  • Installs permanently in a table top, wall or ceiling
  • Half-supercardioid polar pattern reduces pickup of background noise, room acoustics and feedback
  • On-surface mounting eliminates phase interference from table sound reflections, giving a natural sound


  • Element: Electret condenser
  • Frequency Response (typical): 50 Hz to 15,000 Hz at 30 degrees incidence to surface
