Neumann U47-FET
Cardioid Condenser Microphone Daily Rate: $30
Features | Technical Specifications | Support
Originally the Neumann U47 was a valve microphone based on the famous Telefunken VF14m "Pentode" valve and production of the tube-based U47 microphone came to an end in 1965. Four years later, with the VF14 tube no longer available, Neumann developers tried to recapture the sound æsthetic of the U47 using transistors and the result was the U47 fet (Field effect transistor), which had the same K47/49 capsule as the U47, and continued in production until 1968. The circuit electronics are quite complicated, using with 7 transistors, one being an FET and though it's generally agreed that it sounds quite different to its older valve counterpart the Neumann U47 fet quickly became a favourite especially in broadcast circles. 40 years on it's one of the most revered vintage mics and is now almost as collectable and sought after as it's valve predecessor.
FEATURES:
The 47fet was intended to be a phantom-powered, FET version of the U47 tube microphone, designed a few years after the VF14 tube at the heart of the U47 became unavailable.
Two versions of the microphone were sold:
- U47feti - male XLR connector
- U47fet - male DIN 41524 (Tuchel) connector
(Each of the above was also available in a "dark matt finish," specified U 47 fet i mt or U 47 fet mt.)
The capsule is shockmounted within the headbasket to reduce mechanical interference.
