KK... capsule heads are part of the variable miniature microphone system. Together with the KM D (nx) or KM A (nx) output stages, the KK... capsule heads form a complete microphone. KK 184 (nx) + KM D (nx) = KM 184 D (nx) or KK 184 (nx) + KM A (nx) = KM 184 A (nx).
KK 185 is a pressure gradient transducer with a hypercardioid characteristic. Attenuation of sound incidence from the side or rear is approximately 10 dB. Minimum sensitivity occurs at an angle of about 120°.
