Description

The Crown® MB-4 is a miniature boundary microphone for multi-miking applications such as teleconferencing, distance learning, boardrooms, courtrooms, and TV or theatrical applications. Double-sided sticky tape is provided for attaching the unit under shelves, on walls, etc. Thanks to its supercardioid pickup pattern, the MB-4 greatly reduces ambient noise and pickup of room reverberation. The result is a clearer sound.

Features:

  • Ideal for teleconferencing, distance learning, boardrooms and courtrooms
  • Has a 15-foot attached cable leading to an XLR-type output connector with built-in mic electronics
  • Half-supercardioid polar pattern reduces feedback, room acoustics and background noise
  • Clear, natural sound
  • Small and inconspicuous
