Factory Matched Stereo Pair of Two M 150 Tube Microphones with EA 170 Suspension Mounts in Aluminum Case


The Neumann Stereo Matched M150 Tube Microphone Kit doubles the power of the M150 by including two microphones that are matched in frequency and sensitivity response. Achieve excellent, professional stereo recordings of instruments, vocals, performances, ambiance and more. Also included are two N149 vintage power supplies, two shock mounts and a road-worthy aluminum storage case.

The M 150 Tube is a modified omni-directional, condenser tube microphone designed for vocal and general instrument recording in the studio. Designed after the classic M 50 tube microphone, the M 150 incorporates many of the features in a modern microphone. The M 150 features a transformerless tube amplifier based on the M 149. This results in warm transparent audio signal character with a very low noise floor.

The titanium diaphragm of the pressure capsule is 12mm in diameter and is exceedingly thin. As requested by top engineers, the head-grille is shaped just like that on the original M 50. The directional characteristic of the M 150 is totally unique, the microphone features a true omni-directional pattern at low frequencies and becomes more narrow with mid and upper frequencies.
