he M147 Tube is a vacuum tube condenser micro-
phone with cardioid characteristic. At the heart of this mi-
crophone is the K47/49 dual diaphragm capsule, inherit-
ed from this model’s now legendary predecessors, the U 47
and the M49.
Following the capsule is a tube that functions as an imped-
ance converter. The next stage is an efficient, transformer-
less output circuit, that guarantees an extremely low self-
noise level. Note: This innovative combination of current
tube technology with the most advanced solid-state circuitry
was decisive in awarding the 1997 TEC Award to the
related M 149 Tube mic.
The M147 Tube can feed extremely long microphone
cables without affecting the quality of the audio signal.
Like all Neumann tube microphones, the M147 Tube
comes with an elegant satin nickel finish.
The microphone is delivered as a complete set in a high-
quality aluminum case. Included with the microphone are
a microphone cable, a metal swivel mount for a mic stand,
and a compact universal power supply for standard mains
sockets. Our modern manufacturing methods makes it pos-
sible to offer this complete set at a very attractive price.
Applications
The famous capsule, together with complimenting tube
characteristics, makes the M 147 Tube especially well suit-
ed as a vocal mic. In addition, it is a superb spot mic for all
types of musical instruments.
The extremely low self-noise of its tube circuitry makes the
mic perfectly suited for use in modern recording chains,
analog and digital.
Acoustic Features
The M147 Tube is addressed from the side where the
microphone body has the diamond-shaped Neumann com-
pany logo. The black color identifies tube microphones.
The capsule is equivalent to the one used in the U 47, and
is the deciding factor in determining the sound characteris-
tic. It has a flat frequency response to the upper midrange,
and a boost of up to 3 dB above 2 kHz.
The headgrille design is a smaller version of the U 47. It pro-
tects the capsule effectively against popping and wind noise.
Polar Pattern
The M147 Tube has a cardioid characteristic, leaning more
toward super-cardioid due to its distinctive capsule design.
At higher frequencies the pattern becomes more direction-
al. This is very similar to the model after which this new
tube microphone was patterned, the U 47 and the succes-
sor, the U 47 fet.
