The M 150 is a unique tube microphone in the tradition of the legendary Neumann M 50 of the 1950s, often quoted as the ultimate microphone for orchestral recording. The M 150 offers the same phenomenal transient response and unique directional characteristic as its ancestor, updated with 21st century technology and improved performance.

Like its predecessor, the M 150 uses a 12 mm small diaphragm capsule, flush mounted in a 40 mm sphere. The capsule itself is a pressure transducer, but the sphere modifies its omnidirectional pattern to become gradually more directional at higher frequencies. The M 150’s condenser transducer is extraordinary in other respects, too: Its ultra-thin diaphragm is made of titanium, a light yet rigid metal, and spaced only 10 microns from the backplate, also made of titanium. The result is a sound transducer with unparalleled transient response. This delicate capsule is protected by an acoustically open headgrille – shaped just like that of the venerable M 50.

The capsule signal is amplified by a tube circuit using a subminiature triode, specially selected for optimal transmission characteristics and lowest self-noise of only 15 dB-A. Unlike its ancestor developed in the 1950s, however, the M 150 does not use an output transformer which might color the sound. Instead of using an output transformer that might color the sound the M 150 relies on an ultra-transparent transformerless output stage for a clear low end, and a wide dynamic range of 119 dB. Microphone has switches for attenuation and a rumble filter.

The M 150 is primarily designed to bring unprecedented detail and realism to orchestral recordings, particularly classical pieces and film scores. Due to its unique “directional omni” characteristic, its outstanding transient response, and a gradually rising sensitivity above 1 kHz, the Neumann M 150 is the perfect microphone for DECCA Tree techniques, including extended surround setups.
