KM 85

Common name: Neumann KM 85

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 85 belongs to the “fet 80” series. The KM 85 is a cardioid microphone designed for close field pickup. Its cardioid capsule features a built-in low-cut filter to compensate for the proximity effect affecting pressure gradient transducers. The microphone amplifier incorporates a switchable -10 dB pre-attenuator. It was manufactured from 1966 to 1990 and was available with standard 3-pin Tuchel connector or XLR-3 (“i” version) in nickel or dark matt finish.
