Half-Spherical Condenser Boundary Microphone - Black

Boundary microphone (half-cardioid) with 3-pin XLR connector and bass roll-off filter, black

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 Classis BM 34 has a half-cardioid polar pattern, which increases the gain-before-feedback and decreases the amount of diffuse ambience. The Classis BM 34 is provided with a bass roll-off filter.

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.
