Vintage Neumann KM 54 microphone in MINT CONDITION. It was previously owned by the Neumann Museum in Berlin and subsequently by a private collector. The AC701K tube is in prime condition, and the microphone delivers exceptional sound. THIS IS NOT A MICROPHONE THAT HAS SAT IN DAMP CONDITIONS OR BEEN WORN OUT BY YEARS OF HEAVY USE. The Neumann KM 54 is one of the finest small-diaphragm microphones ever made—as evidenced by its use on recordings by Bob Dylan, The Beatles, and others. Comes with your choice of a Leo Schaal PSU or a Neumann N52a PSU, plus a Neumann shock mount. Testing and shipping available.
