The Neumann U 47 fet is a large-diaphragm condenser microphone with a cardioid directional characteristic and fet 80 circuit technology. It was instrumental in shaping the sound of the 1970s. As the transistorized successor of the U 47, it permitted the processing of very high sound pressure levels for the first time, allowing positioning directly in front of loud amps, for instance. Due to this feature and the capsule sound derived from its famous tube-based predecessor, the U 47 fet contributed to many legendary recordings of the time.

Now the U 47 fet is back. For the Collectors Edition U 47 fet, Neumann has resumed production of this classic mic according to its original production documents and schematics. The Collectors Edition is supplied with a high-quality wooden case with special packaging, and an individual certificate with the serial number of the microphone.

Like it's predecessor, the U 47, the U 47 fet employs the K 47 capsule which features a slight boost in the frequency response above 2 kHz. This mic, like the U 87, is characterized by its wide dynamic range.

If required, a switchable low-cut filter raises the lower cutoff frequency electronically from 40 Hz to 140 Hz, and switchable attenuation can reduce transmission levels by 10 dB. In addition, to prevent overloading of the connected preamp, the output signal can be reduced by 6 dB via a switch on the bottom of the microphone.

  • Neumann U 47 fet Collector's Edition Cardioid Microphone
  • Wooden box
