U 47 fet i
From Neumann:
Introduced in 1972 as a successor to the legendary U 47 tube microphone, the U 47 fet became a Neumann classic in its own right. Its smooth yet defined character shaped the sound of the 70s. After a long hiatus, the U 47 fet is finally available again, meticulously reproduced from the same components. A true classic, yet far from outdated.
“Smooth” is the word that best describes the sonic ideal of the seventies. The then new U 47 fet was very much part of that sound. Introduced in 1972, it soon became a studio favorite combining the refined sound balance of its tube predecessor with a new clarity and greater ease of use. Toward the mid-80s, as records became increasingly more strident, the smooth U 47 fet fell out of favor as a vocal microphone and was discontinued. Yet over the years top engineers discovered new applications for the U 47 fet in front of guitar cabinets and kick drums. Eventually, famous vocalists from boy group pop to heavy metal reestablished the U 47 fet as a versatile vocal microphone. So now, by popular demand, it’s back in production.
The U 47 fet uses the same K 47 large diaphragm condenser capsule and the same headgrille design as its tube operated predecessor, the legendary U 47, which revolutionized the recording and broadcast industries from 1949 to1960. For sonic continuity, the U 47 fet also uses a similarly oversized output transformer. Otherwise, its transistorized head amplifier is an amazingly advanced design and a testament to Neumann’s state of the art engineering. This “vintage” microphone has a dynamic range of 119 dB!
