The MB4 is a miniature boundary microphone for table-top installation. Thanks to its supercardioid pickup pattern, the MB4 greatly reduces ambient noise and pickup of room reverberation. The result is a clearer, more intelligible sound for applications such as teleconferencing, distance learning, boardrooms and courtrooms.

The MB4 has a cable leading to an XLR-type output connector with built-in mic electronics. It is powered by 12 to 48V phantom power and is low-impedance balanced.
