Neumann KK133 - Diffuse-field equalised omni capsule - Nickel
The Neumann KK 133 is a diffuse-field equalized pressure transducer with a free-field treble boost (4-5 dB at 12 kHz). The detachable sound diffraction sphere provides a very smooth treble rise, associated with increasing directivity. The frequency response in the diffuse sound field is flat up to 12 kHz. The capsule is made of titanium. Nickel finish.
Neumann 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).
