Neumann M 50 V Set - Modern Reissue of the Legendary Tube Microphone
The Neumann M 50 V Set is the official reissue of the iconic 1950s M 50 small-diaphragm tube microphone, hand-built in Germany to the exact original specifications with modern manufacturing precision. Featuring a pressure transducer capsule mounted on a small sphere for diffuse-field equalized response, it delivers the legendary open, airy, and natural sound that made the M 50 the reference for Decca Tree and classical/ensemble recording. With the same KK 50 capsule, AC 701 tube, and transformer-coupled output, the M 50 V Set captures unmatched depth, transparency, and spatial imaging for orchestral, chamber music, solo instruments, and high-end stereo applications.
Iconic Sphere-Mounted Capsule
The heart of the M 50 V is the KK 50 pressure capsule mounted inside a 40 mm acrylic sphere, creating a diffuse-field equalized response that is exceptionally flat in reverberant environments. This unique design minimizes comb filtering and delivers a natural, uncolored pickup of room acoustics and direct sound, making it the definitive microphone for Decca Tree arrays, ORTF stereo, and far-field placement in concert halls and studios.
