The 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.

NOTE: This is a RESTOCK item that has had its box opened or has been repackaged. It may have minor cosmetic flaws and may have been sold to a customer and returned. Please contact your Sales Representative for more information on this and other products.

AKG MB3 Features:

  • Ideal for teleconferencing, distance learning, boardrooms, courtrooms and security
  • Small and inconspicuous
