Neumann M 150 TUBE

M 150 TUBE description:

The Neumann M 150 Tube Microphone 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 Neumann M150 Tube is not a reissue but an entirely new microphone in its own right.

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.

The dynamic range of the Neumann 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.
