Neumann Nine Pattern Tube Mic with K49 Capsule, 7 Filter Position, N149A, EA170, KT8 & Case, 20Hz-20kHz Frequency Response, 1000 Ohms Load Impedance

The Neumann Nine Pattern Tube Microphone 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 transformer less 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 head grille. 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
Transformer-less 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 K49 capsule - well known from the legendary U47 and M49 microphones - as well as a modern tube and high quality amplifier output stage, the M149 Tube delivers exceptional signal character and response. A frequency response of 20Hz to 20kHz and SPL rating of 136dB < 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 (-3dB).

Shock Mounted Capsule
The capsule is mounted elastically inside the head to minimize structure borne noise.

EA170 Shock-Mount
The elastic EA170 microphone shock-mount is included and even further minimizes noise caused by handling.
