Neumann M150 OMNIDIRECTIONAL For decades the Neumann M50 has been one of the most sought-after microphones, combining phenomenal transient response and unique directional characteristics to become a classic. The new M150 incorporates the best features of the M50 into a very modern microphone. With low self-noise, titanium membrane and capsule, and transformerless tube amplifier, the M150 Tube is not a reissue but an entirely new microphone in its own right. The M150 Tube is ideal for stereo, 5.1 or 7.1 surround recording, particularly the DECCA Tree technique.
