Let's FET it on

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 designed 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.

Featuring Heiserman Designed capsules.

We worked with acclaimed capsule designer and manufacturer Eric Heiserman to develop a fresh take on the classic K47 German capsule design. Eric worked with the United team and our capsule manufacturer to develop a new capsule from the ground up, that we are very pleased with. The capsule is open, articulate, and very three dimensional. This process required the analysis of everything from the sourced Mylar to the thread types of screws; but after many months and many iterations, we finally achieved what we 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, and stringently listened to and tested.

Custom Cinemag Transformers.

We auditioned many recreations of the original German transformer; but 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, quiet operation.

While we could have used smaller or less expensive transformer; we simply refused to compromise. We believe you’ll be glad we didn’t. This Cinemag transformer was truly everything we could hope for.

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.

That was our inspiration: deliver the real product: affordably. The UT FET47 represents our true passion for microphones, and was built with a holistic-design approach. With over 50 years of combined industry experience, we at United have spent years on research and development on this microphone. 

We fell in love with a classic all over again, and we can’t wait to hear the recordings you make with it. Check it out at your favorite dealer today!

“I could go on and on, but I'll leave it like this: It's a workhorse mic designed for heavy use with the flexibility to shine wherever I toss it. So grateful it's in my studio now. Definitely get one when you can! They're hard to keep in stock for a reason. Bravo United!”
