Through-mount
Beyerdynamic BM 32 and BM33 are discreet condenser microphones are intended for integration within conference or boardroom tables and can also be used for telephone and video conferencing systems. Extremely small, for installations where mounting space is limited or a very inconspicuous microphone is needed, they are mounted through a 20mm hole using a fixing nut on the threaded body of the microphone, in tables, ceilings and wall. Elastic bearing rings achieve mechanical isolation from the mounting surface and therefore offer effective sound isolation of the microphone. When used with the bearing rings, a hole of 24mm diameter is required.BM 33 has a half-spherical response. The body of the microphones has an integral 3-pin XLR connector. They require phantom power 8-52V. Head diameter is 30mm. Suits a maximum table thickness of 57mm.
