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 143 is a pressure gradient transducer with wide-angle cardioid characteristic. Attenuation: 4 dB at 90°, 8 dB at 135°, and 11 dB at 180°. The frequency response for sound sources within an angle of ± 90° (off axis) is parallel up to 12 kHz.
