Neumann KK 145 Cardioid Miniature Capsule Head (Nickel)

Cardioid Miniature Capsule Head with Low Frequency Roll-Off - Nickel

The capsule heads KK 131, KK 143, KK 145, KK 183, KK 184 and KK 185 are part of the variable digital miniature microphone system.

KK 145 is a pressure gradient transducer with cardioid characteristic just like the KK 184. However, it has an acoustic bass roll-off characteristic in the free field and therefore suppresses interfering LF noise (wind, structure-borne noise).

Since proximity effect is a natural feature of pressure gradient microphones, the KK 145 appears to be optimized for a flat frequency response at a recording distance of approximately 15 cm (speech cardioid).
