PartsMMC4006 capsule on the MMP-A preamplifier
GridsNear-field DD0251 (silver, pre-mounted): neutral in the near (direct) field. Diffuse-field DD0297 (black): lifts the highs to make up for air absorption in the far field. Close-mic DD0254 (silver, trapezoid): rolls off the highest frequencies for close miking of bright transients.
