he M 149 Tube is a variable dual-dia­phragm microphone. The K 49 capsule – well­known from the legendary U 47 and M 49
microphones – is followed by a tube func-tion­ing 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 very 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. It allows a very fine adjustment of the

cut-off frequency.

Applications

There are nine polar

patterns to choose

from, making this mi-

crophone an ideal

choice for a wide range

of recording situations.

As its ancestors, the

M 149 Tube is a superb

vocalist microphone, not

only because of the cap-

sule, but also due to its

modern circuitry, character-

ized by extremely low noise

level.

Acoustic features

the polar patterns.

The capsule is mount-

ed elastically inside the

headgrille to eliminate

structure borne noise. The

surface below the capsule is

shaped like a cone to disperse
any reflected sound from the
acoustic upper half space.
This avoids any interference
with the primary sound arriv­ing at the capsule directly.

A large headgrille surrounds
the capsule. It is acoustically
very open and therefore in­creases the sonic realism.

The design of the microphone
is a registered design of
the Georg Neumann GmbH
in certain countries.

The M 149 Tube is addressed
from the front, marked with the
Neumann logo. Also on the front

is the switch for the selection of
