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.The MPC 23 is designed for applications such as tele/video conferencing, recording or amplification of round table discussions and wherever the microphone needs to be as unobtrusive as possible.
