M150 TUBE

Condenser Tube Microphone

Overview

The M 150 Tube Microphone from Neumann is a modified omnidirectional, 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 omnidirectional 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 12 mm titanium pressure diaphragm handles high sound pressure levels and provides detailed sound reproduction.

Modified Omnidirectional

The M 150 is a fully circular, omnidirectional microphone at lower frequencies and has a narrower pick up with mid and upper frequencies.
