This is a used 1990 Neumann M-149 tube microphone. This particular example, serial number 3384, is in MINT condition and includes the original box, original wood case, original soft dust case, original elastic suspension, original power supply and original cables.
Despite being 21 years old, this mic is as new, and includes all of the original accessories! As can be seen, this mic wasn’t used much, and has spent the majority of it’s existence tucked away in a studio’s storage facility.
The M 149 tube is a variable dual-diaphragm microphone. The K 49 capsule – well-known from the legendary U 47 and M 49 microphones – is followed by a tube functioning as an impedance converter. In contrast to earlier concepts â utilizing a transformer â the tube is complemented with a transformerless output circuit design.
The M 149 tube can thus feed long microphone cables without any coloration. Two slide switches are located below the large, acoustically very open headgrille. The switch at the front allows selection one of nine directional patterns. The slide switch at the rear operates a seven-step high pass filter. It allows a very fine adjustment of the cut-off frequency.
As its ancestors, the M 149 tube is a superb vocalist microphone, not only because of the capsule, but also due to its modern circuitry, characterized by extremely low noise level. The microphone comes as a set in the original box, together with the 8-core microphone connecting cable, the N 149 A power supply with plug-in mains unit, the EA 170 full elastic microphone suspension and a dust cover.
