Classis BM 34

Common name: Beyerdynamic Classis BM 34

Production Status: In production

The Classis BM 34 is a condenser boundary microphones designed for flush mounting into tabletops or ceilings. It is ideal for applications such as tele or video conferencing, recording or amplification of round table discussions and wherever the microphone needs to be as unobtrusive as possible. The microphone features the innovative Scudio technology, making it 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 adds a bass roll-off filter while the Classis BM 33 has a half-spherical polar pattern making it ideal for large rooms. The high sensitivity guarantees a constant output level even from long distance sources. Elastic bearing rings provide mechanical isolation from the mounting surface and therefore offer excellent sound isolation. It is available in Black (B), White (W) and Silver (SE).
