Description

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 high quality 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.

Features:

  • Half-spherical polar pattern
  • RFI-proof due Scudio™ technology
  • High-quality non-glare design
  • Linear frequency response
  • Suitable for miking speech
