KM 83
Common name: Neumann KM 83
Production Status: Discontinued / Vintage
KM is the acronym for “kleinmikrophon” meaning “little microphone”. Georg Neumann GmbH first introduced this type of microphone in 1953 with the KM 53. The KM 83 belongs to the “fet 80″ series” of Neumann’s transistorized P 48 (phantom powered) microphones. The KM 83 is a descendant of the KM 63 tube microphone developed around the same high quality KK63 / KK 83 omnidirectional capsule with MCF diaphragms. This miniature microphone has a switchable -10 dB pre-attenuation pad and was manufactured from 1966 to 1992, when was it replaced by the new transformer-less KM 183i. It was available with standard 3-pin Tuchel connector or with XLR-3 connector (KM 83i) in nickel or matt black finish.
