Acoustical Boundary Microphone
The MPC 22 has been designed for flush mounting into tabletops, ceilings or walls. The unobtrusive design makes them ideal for use in round table discussions, tele/video conferencing or wherever a low profile microphone is needed.
The MPC 22 has a semi-cardioid polar pattern, which
increases the gain-before-feedback and reduces the ambient
noise.
