APPLICATIONS
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/video
conferencing, recording or amplification of round table discussions
and wherever 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 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 achieve mechanical isolation from the mounting
surface and therefore offer effective sound isolation of the micro-
phone.
