Heritage Audio FET47 – Large-diaphragm FET Condenser Microphone

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.
