Neumann M149 Tube Overview

  • 1Description

The M 149 Switchable Tube Microphone from Neumann is a variable dual-diaphragm microphone. The K 49 capsule, well known from the legendary U 47 and M 49 microphones, is followed by a tube functioning as an impedance converter. In contrast to earlier concepts utilizing a transformer, the tube is complemented with a transformerless output circuit design. The M 149 Tube can thus feed long microphone cables without any coloration.

Two slide switches are located below the large, acoustically open headgrille. The switch at the front allows selection one of nine directional patterns. The slide switch at the rear operates a seven-step high pass filter, allowing very fine adjustment of the cut-off frequency.

Transformerless Tube Output Circuitry
Transformerless output circuit, triode tube and integrated amplifier provide a signal output stage featuring very low self-noise and distortion. The final output stage is an integrated amplifier that provides a very high output signal and the frequency response curve is unaffected by high, transient signal levels resulting in warm, transparent signal reproduction.
Exceptional Signal Reproduction
Utilizing the legendary K 49 capsule - well known from the legendary U 47 and M 49 microphones - as well as a modern tube and high quality amplifier output stage, the M 149 Tube delivers exceptional signal character and response. A frequency response of 20 Hz to 20 kHz and SPL rating of 136 dB < 5% THD result in pristine audio reproduction at various dynamic range.
9 Selectable Polar Patterns
Omnidirectional, wide angle cardioid, cardioid, hypercardioid and figure 8 polar patterns are provided. Intermediate positions of each are located in between the pattern designations.
Low Frequency Roll-Off Switch
A 7-position low frequency roll-off switch is located at the rear of the microphone. It selects a high-pass filter, advancing in half-octave steps between 20 Hz and 160 Hz (-3 dB)
Shock Mounted Capsule
The capsule is mounted elastically inside the head to minimize structure borne noise.
EA 170 Shock-Mount
The elastic EA 170 microphone shock-mount is included and even further minimizes noise caused by handling.
