The KK 133 is a diffuse-field equalized pressure transducer with a free-field treble boost (4-5 dB at 12 kHz). Based on the technical design concept of the legendary Neumann M 50 microphone and its successor, the M 150, its ultra thin diaphragm is made of titanium and is spaced only a few microns from the backplate, also made of titanium. The KK 133 capsule attains an incredibly fast transient response with unprecedented accuracy.

Its included detachable SBK 133 sound diffraction sphere creates an earlier and gentler increase in sound pressure for mid to high frequencies. Directivity thus increases in the upper frequencies as with a cardioid capsule, yet as a pressure transducer the KK 133's bass transmission is linear down to the lowest frequencies, with no proximity effect.

The combination of the capsule KK 133 with the analog output stage KM A is only one of the numerous options within the modular Neumann KM A/D small diaphragm microphone system. Eight different small diaphragm capsules (KK 120 up to KK 185) may be combined with either an analog output stage (KM A) or a digital AES 42 output stage (KM D). A comprehensive range of accessories ensures adaptability to the most diverse fields of application.
