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.
