The AKG MB3 is a miniature boundary microphone for multi miking applications such as teleconferencing, distance learning, boardrooms, courtrooms, and security applications.

Description

AKG High-Performance Flush-Mount Boundary Layer Microphone
for Theater, Conference & Lectern, Meeting Room and Security Applications

The AKG 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.

Features
  • 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 refl ections, giving a natural sound
