Neumann M 150 Tube Omnidirectional Tube Microphone

Large Diaphragm Omnidirectional Condenser Tube Microphone

The Neumann M 150 Tube Microphone 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.

Features:

• A General Studio Use Reproduction of a Classic
  The Neumann M 150 Tube microphone is a specialized tube model for vocal and general instrument recording in the studio, designed after the classic M 50 tube microphone but incorporating many features of modern microphones.
• Tube Circuitry
  The M 150 tube design results in smooth warm audio character, and the transformerless audio retains a high output while maintaining a low noise floor.
• Titanium Pressure Diaphragm
  The 12mm titanium pressure diaphragm handles high sound pressure levels and provides detailed sound reproduction.
• Modified Omni-Directional
  The M 150 is a fully circular, omni-directional microphone at lower frequencies and has a more narrow pick up with mid and upper frequencies.
