The M 147 Tube is a vacuum tube condenser microphone with
cardioid characteristic. At the heart of this microphone is
the K 47 dual diaphragm capsule, inherited from this model's
now legendary predecessors, the U 47 and the M 49.
Following the capsule is a tube that functions as an impedance
converter. The next stage is an efficient, transformerless
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 M 147 Tube can feed extremely long microphone cables
without affecting the quality of the audio signal. Like all
Neumann tube microphones, the M 147 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 possible to offer this
complete set at a very attractive price.
