Neumann M 150
Large Diaphragm Transformerless Cardioid Tube Condenser Microphone with Titanium Capsule and Membrane
Taking the best characteristics of Neumann's legendary M50 mic, the transformerless M 150 is truly a modern masterpiece.
The first mic we know of to employ a titanium capsule, the M150 has a singular pickup pattern, not quite omni directional, not quite cardioid, making it ideal for a variety of stereo mic'ing techniques, especially the Decca Tree technique.
Hands down the mic to have on hand for orchestral and string sessions.
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 re-issue but an entirely new microphone in its own right.
Includes aluminum flight case, cables, N149A Power Supply, EA170 elastic suspension mount.
Neumann M 150 Features :
- All Titanium capsule handles high sound pressure levels and provides detailed sound reproduction
- Unparalleled transient accuracy
- Pressure omni capsule for extended low frequency response
- Modern version of the world-famous M 50
- Transformerless tube amplifier based on the award-winning M 149 Tube microphone
- Tube circuitry design results in smooth warm audio character, retains a high output while maintaining a low noise floor
- Low Frequency Roll-Off advancing in half-octave steps between 20 Hz and 160 Hz (-3dB)
- Very low self noise of 15 dB-A
- Ideal for DECCA Tree recording and surround miking techniques
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 M 150 takes many of the original M 50's desirable features and incorporates them in a very modern microphone. Now as a redesigned classic with state-of-the-art circuit technology and correspondingly low self-noise, like the legendary M 50, this tube microphone is ideal for orchestral recording and small acoustic ensemble recording, in addition to capturing full-bodied vocals.
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.
