Mounting Plate for Directional Boundary-Layer Technique

  • for directional boundary-layer recording with cardioid and supercardioid microphones
  • often used at the stage edge in opera live recording
  • avoids “comb filter” effect
BLCg with CCM41Lg

Turns any directional (e.g. cardioid or supercardioid) CCM Compact Microphone or MK capsule with Active Cable into a boundary-layer (PZM) microphone. This is especially useful when recording moving singers/ actors on a stage, or when a microphone on a stand would be obtrusive.

The boundary layer effect creates a 3 dB increase of the Direct-to-Room ratio. Thus, an increase of the recording distance is possible without negative effects.

A rubber ring built into the bottom of the plate prevents inadvertent rotation of the plate or marring of the surface on which it is placed.
