The Classis BM 32 / 33 / 34 condenser boundary microphones have been designed for flush mounting into tabletops or ceilings. The microphones have been designed for applications such as tele/videoconferencing, recording or amplification of round table discussions and wherever the microphone needs to be as unobtrusive as possible. 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.
