MB-4

Common name: Crown International MB-4

Production Status: In production

The MB-4 is a miniature phase coherent cardioid boundary microphone for multi-miking applications such as teleconferencing, distance learning, boardrooms, courtrooms and TV or theatrical applications. Its supercardioid pickup pattern greatly reduces ambient noise and pickup of room reverberation, resulting in clearer sound. Double sided sticky tape is provided for attaching the unit under shelves, on walls, and so on. Its permanently attached tubular electronics module provides balance mic level output.

The MB-4/E is the same, but without the electronics/connector, and must be used with the Crown MB-100 or MB-200 interface (not included).
