NEUMANN KM 145A nx
The combination of the capsule KK 145 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.
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).
