The Classis BM 32 condenser boundary microphones have been designed for flush mounting into tabletops or ceilings. The microphones have been designed for applications such as tele/video conferencing, recording or amplification of round table discussions and herever the microphone needs to be as unobtrusive as possible. All microphones feature the innovative Scudio technology, making the microphones absolutely insensitive to wireless communication devices such as mobile phones. The Classis BM 32 has a half-cardioid polar pattern, which increases the gain-before-feedback and decreases the amount of diffuse ambience. The Classis BM 34 corresponds to the Classis BM 32, but is provided with a bass roll-off filter. The Classis BM 33 has a halfspherical polar pattern making it ideal for large rooms. 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.
