KM 63

Common name: Neumann KM 63

Production Status: Discontinued / Vintage

The original KM family ( KM 53 – KM 54 – KM 56) was born in the 50’s as a result of the professional market request for high quality, but very small, microphones, ideal for TV productions. After ten years Georg Neumann GmbH launched a new KM tube series. The same Telefunken AC 701 k tube was used to design the new pre-amplifier and the new 21 mm capsules employed MCF made diaphragms. The new series was compatible with most of the old KM 5x series accessories, as cables, holders and PSU’s. The tube cathode coupling derived coming from the last “c” version yields lower noise figures. The KM 63 replaced the KM 53 as miniature pressure condenser microphone for professional purposes and it was manufactured from 1964 to 1971.
