BLCg, Boundary-Layer Adaptor plate

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. 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.
