Acoustical Boundary Microphone
The MPC 23 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 23 has a semi-spherical polar pattern which
allows it to pick up sound from all directions.
