Schoeps BL CCM 3 Boundary-Layer Microphone for fixed table installations

This special version of the CCM 3 Lg compact microphone is equipped with a flange enabling it to be built into the surface of a table or speaker's rostrum. This makes the microphone nearly invisible, and at the same time improves the sound quality by eliminating comb filter effects.

  • hemispherical pickup pattern
  • for building in to the surface of a table or lectern
  • unobtrusive
  • avoids “comb filter” effect
