The MPC 23 acoustical boundary microphone is designed for
mounting into tabletops and ceilings. The half-spherical
polar pattern is picked up in a uniform manner. The high
sensitivity guarantees a constant output level even from long
distance sources. Elastic bearing rings achieve mechanical
isolation from the mounting surface and therefore offer
effective sound isolation of the microphone.
