Sound Pure's Take

We are thrilled to hear the news that Neumann is reviving the U 47 FET. We've seen a handful of other modern mic manufacturers make good sounding clones of this mic, but now you can get the REAL DEAL U 47 FET without the hassles that come with vintage mics.

It's important to note that this isn't a half-hearted re-issue with vintage parts swapped out for modern cheap equivalents. Neumann tells us that this limited edition run is EXACTLY the U 47 FET as it was made in the '70s. They just paused production for 40 years, and have now started building more using all the same parts and manufacturing techniques.

Take note - this revival of the U 47 FET is a very limited run. Neumann only has enough parts to make about 100 of these, so be sure to get yours before they're all gone.

From Neumann USA

The 1960s and 1970s are considered to be one of the most innovative periods in the history of music. Many sound concepts of this pioneering time are currently being rediscovered and are regarded as a great enrichment – particularly in the digital audio world. The interplay among studio technologies of different generations forms the basis of unprecedented freedom for new sound experiments.

An icon of that era which was decisive in helping to shape the sound of the 1970s is the Neumann U 47 fet. As the transistorized successor of the U 47, it permitted the processing of very high sound pressure levels for the first time, for instance allowing positioning directly in front of loud amps. 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 new “Collectors Edition U 47 fet”, Neumann has resumed production of this classic mic, according to the 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.

The list of renowned artists who have created musical masterpieces with the sound of the U 47 fet – including AC/DC, Kate Bush, Bruce Springsteen, and later R.E.M, the Pretenders, a-ha, Dire Straits, Metallica, Michael Bublé and many others – can now grow longer...

In terms of technical design, the U 47 fet is a large-diaphragm condenser microphone with a cardioid directional characteristic and fet 80 circuit technology. This technology, also used in the U 87, is characterized by a wide dynamic range. 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.

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.
