U47 Zeitmaschine.... (the
time machine)
Can a U47-remake be as good as the original ?
Please let me introduce myself: My name is Gunter Wagner. I am specialized in tube microphone technology since more than 27 years. My special field for more than half of my life is the Neumann U47, since I fell in love with its sound and its technical design when I worked as a sound engineer in Germany in the early seventies.
The more I
learned about tube microphones in the following years, the more I respected this
particular microphone.
Considering that it was designed shortly after WW2 - at a time when it was hard
to find sources for unusual parts and materials in Germany - its historical
impact on the recording industry from the early 50's until today is undisputed.
Other microphones at that time were often electronically more complex, but
mechanically very... well,.. simple. This often made them unreliable and
sometimes even sounding a bit 'tinny'. The U47 is completely the other way
around: Mechanically very solid and complex in important details (like its
unique flexible tube suspension, the capsule interconnection or the
sophisticated triple layer mesh in the grille), the U47's circuit design has a
brilliant simplicity.
There was no computer simulation in 1948, and test equipment for acoustical
measurements and research was simple and vague, at least for today's standards.
Nevertheless the U47 turned into a
milestones in
German recording technology
and became one of the world's best and most sought-after microphones.
But as we know, even the most ingenious design does not guarantee a world-class
sound, so here is the question: Did they know 1948 what they were doing or was
the U47 just a "lucky shot" ?
I am afraid, we will never find out...
keeping the old Neumann U47
alive...
When Neumann more
and more ran out of original U47 parts in the early 80's, we had to start
re-manufacturing U47 parts to make sure that we could
continue professional service for the old classic U47. Meanwhile we supply
authentic U47 spareparts to many microphone
technicians and manufacturers around the world. (See
www.tubemicrophones.com and
www.german-tubemics.com)
Since 1989 we re-make most key parts of the old U47
and a few years later I built the first completely new U47-reproduction as a
special order for one of my clients in the USA.
The response was overwhelming. Finally it was
possible - by matching capsule, tube and output transformer in
combination with the fully authentic U47 body-mechanics - to achieve 100% of the
look, feel and the sonic quality of the classic U47.
Not just a copy of an old U47 with all its problems, but making U47 to
the quality and sound when they were new, 55
years ago.
Because
the U47w is made from U47 spareparts, basically
each part - from the mechanics, the body and the head to the transformer and the
capsule - is directly interchangeable and fully authentic
to the old Neumann part in an old U47. In other words, if you take the
headgrille or a capsule or even the output connector, it fits
directly to an old Neumann U47 because it does not just look
as the original, it is always a fully
authentic replacement part for the Neumann U47.
Meanwhile we built
more than 150 U47w for clients around the globe who find
it amazing that they can now use a true U47 without the
limitations and
unpredictability of a 55 year old mic. Output gain, frequency
response, noise, distortion and the famous character - all specs are identical to the
vintage U47.
