Classis BM 43 B

Boundary Microphone (half-spherical) with 3 m (9.8 ft) cable with free ends, black

The Classis BM 43 is a small condenser boundary microphone with a half-spherical polar pattern for round table discussions, teleconferences, studio and live recording. The robust housing is of a highquality design and covered with very exclusive, dust repellent fabric. The matt, non-glare surface allows integrating the Classis BM 43 discretely into each installation. The integrated high pass filter reduces low-frequency noise from tables and other. The increase of the sound pressure at a boundary results in a higher gain, signal-to-noise ratio and comb filter effects cannot occur.

The Classis BM 43 is available in matt black or white.
