Crown MB4 Supercardioid Boundary Microphone

The MB4 from Crown Audio is a compact, low-profile microphone for capturing audio in teleconferencing, distance learning, courtroom, boardroom, TV, and theatrical applications. The slim lightweight microphone is easily mounted to any surface using the included double sided tape. The MB4 features a half-cardioid polar pattern which is effective in minimizing surface and vibration noise while providing a generous pick area around the top and off-axis sections of the capsule. The electret condenser element provides a wide frequency response, resulting in great audio detail and presence. The user programmable switch enables standard On/Off, push-to-talk and push-to-mute functions.
