The most modern build materials and manufacturing techniques have been employed by Georg Neumann to create the M 150 Tube, a microphone that uniquely exploits the heritage of a revered classic design, while exhibiting a performance capability at the very limits of modern acoustic and electronic engineering. The instantly recognisable head-grille recalls the famous M 50 from which the M 150 derives its distinctive acoustic characteristics and operating principle. First introduced some 50 years ago, the M 50's clarity and realism earned it a repuation as an orchestral microphone of choice, most notably in the DECCA tree configuration.

The omnidirectional, pressure gradient transducer provides excellent transient response and low frequency reproduction. By mounting the surface of the diaphragm flush to a small (40mm) sphere, the capsule acts as a pure omnipressure transducer at the lowest frequencies, delivering a perfectly circular polar pattern. This pattern narrows increasingly through the mid and upper frequency ranges, forming a unique directional characteristic, ideal for natural stereo recording, or indeed, 5.1 and 7.1 multi-channel techniques.

This same operating principle is retained in the M 150, but Neumann's engineers have undertaken ground-breaking work on the use of high grade titanium in capsule design which has resulted in the development of a very thin 12mm diameter diaphragm, producing greatly improved response characteristics. The M 150 employs the same sophisticated power supply and transformerless output circuitry as the award-winning M 149 Tube, improving the reproduction of low level and low frequency signal information, and avoiding the phase problems and low level signal typical of transformer based design. The M 150 Tube is available individually, or in consecutive serial number, stereo pairs. Included with each mic set are wooden mic cases and vintage-design power supplies, all contained in a high-density foam-lined flightcase.
