United Studio Technologies UT FET47 Condenser Microphone

Painstaking recreation of the U47 FET large diaphragm condenser microphone featuring a Heiserman German-style dual-backplate K47 capsule and custom Cinemag transformer
MFR# UT FET47c

Product Description

The United Studio Technologies UT FET47 Condenser Microphone has been painstakingly recreated with the utmost attention to detail. Realism and thickness that is true to the vintage sonics ia now available at an affordable price.

It’s a labor of love. The UT FET47 represents several years of R&D, blood, sweat, and tears — all to capture the essence of one of the most beloved and classic solid state condenser microphones, and recreate it for the modern recordist.

The sonic qualities you’ve been chasing have arrived — at an accessible price, with uncompromised quality.The UT FET47 features a custom Cinemag transformer, a custom Heiserman HZ series capsule, vintage polystyrene capacitors, and NOS (new old stock) FETs. Custom parts. Vintage new-old-stock parts. Mix that together with each microphone being built in the USA by actual recording engineers, and you have the UT FET47.

HEISERMAN CAPSULES

United worked with acclaimed capsule designer and manufacturer Eric Heiserman to develop a commercially produced version of his recently perfected German style dual-backplate K47 capsule. Eric worked with the United team and our capsule manufacturer to faithfully reproduce his capsule. This process required the analysis of everything from the sourced Mylar to the thread types of screws; but after many months and many iterations, they finally achieved what they had hoped for in the HZ Series capsules.

While many of the HZ Series design secrets will remain so, one superior attribute we can reveal is the use of dual, matched backplates. With the HZ Series matching process, a far more accurate and consistent quality from side to side and capsule to capsule is achieved.

The HZ series capsule is still manufactured only a few at a time, stringently listened to, and only are used if they meet both our and Eric’s expectations.

CUSTOM CINEMAG TRANSFORMERS

Many recreations of the original German transformer were auditioned, but United quickly settled on an exceptional offering from Cinemag Transformers in California. Their answer to the classic part is truly a piece of art; a large, hefty transformer made from a ‘striped core’ of interleaved sets of high nickel and steel laminations, and wound to the specs of the original. It‘s humbucking design delivers clean and quiet operation.

IT’S NOT JUST ANOTHER MIC — IT’S A UNITED

Choosing the best microphone for your needs couldn’t be any more difficult these days. With so many options on the market, and so many claiming to have the vintage sound and failing to deliver, it can be overwhelming. The UT FET47 represents true passion for microphones, and was built with a holistic-design approach. With over 50 years of combined industry experience, United have spent years on research and development on this microphone.

I recently budgeted $4K to invest into some studio upgrades. There were a couple of areas that needed improvement, namely my kick drum, upright bass, and bass amp sounds. (Overheads as well).

I bought both the UT FET 47 and a Neumann U47. I thought if the Neumann was that much better, I’d buy right and buy once, never having to think about it again. I had 30 days to return either.

I did non-blind A/B testing on upright bass and kick drum, they sounded very similar, but the Neumann won every time. I could hear the extra dimension, a little more musicality, just that magic 3D of the Neumann.

But…. then I did a blind A/B test. I was shocked, but the UT won every time. I thought, “that’s without a doubt the Neumann”, every time. wtf? The magic 3D of the Neumann was all in the badge? I’m not sure, maybe if I did more rigorous A/B'ing, such as off-axis testing, I would have heard a difference? Maybe.

For my needs, kick, upright and electric bass amp, the UT had me convinced. The feel and build quality of the UT felt comparable to the Neumann, and the performance was clearly a match. The UT coating was slightly more shiny than the Neumann, so on that end, I preferred’d the more subdued look of the Neumann. But for $4K vs $799, I will deal.

With the $3200 savings I bought a pair of Beyer M160’s and a Heiserman H47 FET. This covered all of my kick drum, bass amp and overhead needs all within my $4K budget. I’d highly recommend checking out the UT and do some blind and non-blind testing for yourself.
