Description

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.

Features

  • Universal tube microphone
  • Pressure gradient transducer with the large diaphragm capsule from the legendary U 47 and M 49
  • Transformerless circuitry
  • Low self noise level
  • Comes with swivel stand mount made of metal, universal power supply, and cable in an attractive aluminium case

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.
