Beyerdynamic Classis BM32 Condenser Boundary Layer Microphone Overview:

The Classis BM 32 condenser boundary microphone has been designed for flush mounting into tabletops or ceilings. The microphone has been 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. It feature the innovative Scudio technology, making the microphone 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 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.
