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. In most FET–80 microphones the FET impedance converter feeds the output transformer directly, but in the U47 FET (and U89), the FET buffer is followed by a further five bipolar–junction transistors, which essentially form a discrete op–amp to drive the output transformer. How does a Neumann U47 fet-80 microphone work? At what angle is the microphone most sensitive to sound?Ġ° is the front of the microphone and the angle where the microphone has its maximum sensitivity. All microphones sold for broadcast or for export were badged with the TELEFUNKEN diamond logo, while domestic products were badged with the Neumann logo. Is Telefunken Neumann?Īt the time Neumann had a worldwide distribution deal with TELEFUNKEN GmbH, as TELEFUNKEN had already established a powerful global distribution network. The VM1S is designed to be the stereo version of Brauner’s high-end VM1 microphone. It is a dual-large-diaphragm multi-pattern stereo tube condenser microphone. In addition to vocals, the U47 is a long-time favorite for classical recordings, where its robust low-frequent handling, airy high end, and switchable cardioid/omnidirectional pattern make it ideal for Decca tree stereo mic arrangements.īrauner VM1S ($10,799.00) The Brauner VM1S is the most expensive single microphone on the market today. What type of microphone is the Neumann u47 FET I?īuilt according to the original production documents and schematics of the classic design, the Neumann U 47 fet i Large-Diaphragm Cardioid Condenser Microphone is a precise reproduction of this often-copied microphone that helped define the smooth sound of the ’70s. FETs take the high-impedance signal from mic capsules and output a usable and proportional low-impedance signal. What is a FET microphone?įETs (field-effect transistors) are active electrical devices that use an electric field from a microphone capsule to control a flow of current that is ultimately the mic signal. Frank Sinatra owned his own U 47 Ella Fitzgerald, Louis Armstrong, Bing Crosby, Tony Bennett and the Beatles also used it. The U47 was especially popular in US studios. Its desirability is based primarily on the synergy of its three sound-shaping components: capsule, tube, transformer. It is amazing how good it sounds with such a straightforward and uncluttered design. Perhaps the most surprising aspect of this mic is the simplicity of its design. Telefunken Company, the U47 quickly became the microphone to use in nearly every recording and broadcast application. What impact did the Neumann U47 have on recording studios?
