Though the M 150 Tube is based on Neumann's classic M 50, the similarities between the two microphones end with their wonderful, warm sound. In terms of design, the M 150 Tube is thoroughly modern. Utilizing a unique 12mm pressure omni capsule mounted in a 40mm sphere, the M 150 Tube has a unique polar pickup, unparalleled transient response, and a low noise floor of 15 dBa. The membrane and capsule are constructed entirely of Titanium. The dynamic range of the M 150 Tube is 119 dB, allowing reproduction of the full musical expression, without restraint. With its low self noise, more gain can be used without risk of adding noise to the final product. Still, the M 150 Tube's rich, expansive sound - ideal for orchestral and small acoustic ensemble recording, in addition to capturing full-bodied vocals - might fool you into thinking you're hearing a classic vintage microphone at work.

Since the 1950s, the Neumann M 50 has been heralded as the ideal microphone for orchestral recording and string scoring. With its phenomenal transient response and unique directional characteristic, this classic mic has endeared many fans, both in the control room and on the soundstage.
The new M 150 Tube* takes many of the features from the original M 50 and incorporates them in a very modern microphone. With low self noise, a Titanium membrane and capsule, transformerless tube amplifier and sophisticated power supply, the M 150 Tube is not a reissue but an entirely new microphone in its own right.
Acoustical features
The Titanium diaphragm of the pressure capsule is 12 mm in diameter and is exceedingly thin. Although Titanium has been known to have unique and desirable characteristics for some time, it has, until very recently, been very difficult to procure in the quality necessary for use in a microphone of this type.
The headgrille is shaped just like that on the original M 50, as requested by various top engineers in the recording industry. Due to mounting the pressure capsule with the diaphragm flush to the surface of a small (40 mm) sphere, the directional characteristic of the M 150 Tube is entirely unique.
At the lowest frequencies, this system is a pure omnipressure transducer with a perfectly circular polar pattern. However, in the mid- and upper frequencies, the pickup pattern becomes more narrow. The M 150 Tube is an ideal microphone for any stereo, 5.1 or 7.1 surround recording, particularly DECCA Tree technique.
Electrical features
The dynamic range of the M 150 Tube is 119 dB, allowing reproduction of the full musical expression, without restraint.
With a low self noise of 15 dB-A, more gain can be used without risk of adding noise to the final product. The transformerless output circuit of this microphone allows for extremely fine reproduction of small signals and low frequency information. Also, long cable runs can be used with no loss of signal quality.
