The combination of the capsule KK 145 with the output stage KM A is only one of the numerous options within the Neumann KM A/D small diaphragm microphone system. The Neumann system KM A/D is a modular microphone system for even the most demanding applications. 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). All components are available in nickel or Nextel black (nx). A comprehensive range of accessories ensures adaptability to the most diverse fields of application. The KK 145 is a pressure gradient transducer with cardioid characteristic just like the KK 184. However, it has an acoustic bass roll-off in the free field and therefore suppresses LF interference (wind, structure-borne noise). Since proximity effect is a natural feature of pressure gradient microphones, the KK 145 is optimized for a flat frequency response at a recording distance of approximately 15 cm (speech cardioid).
