S/N Ratio: 84 dBA According to Andreas Grosser, at least 5 different models of output transformer were used within the U 47. Each system includes a pair of U47 microphones matched in frequency response. The TELEFUNKEN Elektroakustik recreation of the U47 large diaphragm tube microphone is exact in every detail, down to the historically accurate BV8 output transformer and M7 capsule. This is a characteristic that Neumann engineers sought to improve in later mics, such as the M 49. To this capsule was added an amplifier built from military surplus VF14 tubes (they had been used in field and aircraft radios), and BV8 output transformers. The Neumann U 47 is also known as: U47. . The approximate physical dimensions of the U-47 are as follows: The U47 was manufactured by Neumann, but initially distributed by Telefunken. Each system includes a U47 and U48 microphone matched in frequency response. Sensitivity: 22 mV/Pa, ±1 dB. Since its original development in 1946, the TELEFUNKEN U47 has been the microphone of choice for generations of recording professionals. Early U47 (and U48) mics contained Neumann’s M7 capsule, in which the brass backplate was covered with a thin PVC diaphragm. Neumann describe the U47 FET as a fixed–pattern cardioid microphone, although it actually has a distinctly hypercardioid response for all frequencies above about 500Hz. The U47 was manufactured by Neumann, but initially distributed by Telefunken. The original U47 employed a steel-jacketed Telefunken VF14 tube, developed by Telefunken specifically for use in microphones. Neumann took over distribution in the 1950s; the mics distributed by Neumann bear a Neumann logo. PVC ages poorly, and as early as 1958 the Neumann factory was using the M7’s successor, a capsule known as the K47/49, which used a metallized polyester diaphragm. Its matte nickel finished body houses a new BV8 output transformer and a newly developed VF14k vacuum tube; a "plug and play" replacement for the rare VF14M tubes found in the original. The U-47 did not maintain equal output levels across patterns. Telefunken U47 Multi-Pattern Tube Condenser Microphone. Telefunken distributed the microphone originally, with Telefunken’s logo badge on the front (as pictured here). Transformer: TELEFUNKEN Elektroakustik BV8. Tube: NOS Philips/Raytheon 5840W. Capsules are tuned to each other; transformers and tube are tested for matched gain and frequency response. Therefore, many early U47s bear the Telefunken logo. Set the "way back" machine for 1958 when you could have walked out of Manny's Music on 48th St. in New York City with a shiny new Gold Top Les Paul for under $1000. They’re exactly the same microphone inside. According to Telefunken Elektroakustik, their VF-14K is made by retrofitting a NOS glass tube into the VF-14’s metal jacket, and matching the VF-14 pinout. The pattern switch was located on the microphone body, and worked by disabling the polarization voltage to the rear diaphragm. Therefore, many early U47s bear the Telefunken logo. According to Heyne, VF14 production began in 1946; because Telefunken was a 25% owner of Neumann, one could reasonably speculate both that Telefunken engineers played a role in U47 development, and further that the U47 was in simultaneous development by 1946. The large, chrome head grille houses a newly manufactured M7 capsule. The first condenser microphone to offer selectable polar patterns (cardioid and omnidirectional), the original U47 also featured the famous M7 capsule which had been developed in 1928 by Georg Neumann. The only difference between Omni and Figure-of-8 patterns is the polarity of the rear capsule.). According to Oliver Archut, a prototype U47 was displayed at the Berlin Radio Show (Berliner Funkausstellung) in 1947. The K47 capsule used a single, shared backplate, which caused tensioning challenges, in that both diaphragms would have to be tuned identically to produce balanced Figure-of-8 or Omni patterns. Neumann U 47 is a large-diaphragm condenser microphone.The original series, manufactured by Georg Neumann GmbH between 1949 and 1965, employed a tube design; the M 7 capsule was used until 1958, then superseded by the K 47.. Neumann U 47 FET was a first reissue, with a head grille similar to the original U 47 but using solid-state circuitry (discrete op-amps) and using the K 47 capsule. Whether you're recording a symphony, a "crooner," or any facet of modern music, you'll find a great tool in the U47. The U 47 could produce either a Cardioid or Omnidirectional pickup pattern. Sausalito, San Francisco, March, 2008 — The phenomenally successful band Journey has recorded a Greatest Hits album plus an album of new material with…, Brett Allen Nabs First TELEFUNKEN U47/48 Studio Set for SnowGhost, Richard X Picks TELEFUNKEN U47 for Will Young’s New Album, Journey Records Double Album With Telefunken USA U47M Mics. TELEFUNKEN Elektroakustik is proud to offer the U47/U48 Studio Set of microphones. The combination of these components created a sonic quality that was absolutely unheard of in the English speaking world of the mid-1940s when darker sounding, less detailed ribbon microphones were the standard. Wide frequency response that captures bass instruments with outstanding focus, punch and power; Fast and detailed response that is perfect for drums and other percussion. They started off with a very large transformer/capacitor package. Whether that was a functional microphone, or whether its capsule and circuit were similar to what was commercially released, is not known. The mic went through three revisions. Everything, from vocals to the loudest of guitar sounds, full on orchestral recording, beautiful backing vocal arrangements, or a chamber ensemble will benefit wildly from the rich and vibrant tone of this stunning microphone.

Power Source: External Power Supply. In the original German-language Neumann documentation for the U47 and similar mics, the term “Niere” — literally “kidney” — is used to denote the Cardioid pattern. Every great singer deserves an amazing microphone, and for more than 60 years the U47 has been that microphone. Maximum SPL (for 1% THD): 125 dB. The introduction of the U47 brought a new level of fidelity to the audio world, and is still considered to be one of the finest microphones ever produced. Units produced before 1950 were … Output Impedance: < 300 Ω. (14 mV/Pa; 35 - 15,000 Hz). Photo by John Neff. The mic was released in 1947. Like the U 47, the fet model used Neumann’s K47 capsule, variously referred to as the K 47, K 47/49 and K 47fet. In keeping with the long standing tradition, TELEFUNKEN Elektroakustik have given a nod back to 1958 when both the U47 and U48 were offered in 3 unique packages. Microphone Set USB studio large diaphragm microphone with USB connection for direct operation on the computer, No additional drivers required, Directional characteristic: cardioid, Frequency response: 30 - 18000 Hz, Sensitivity: 25 mV / Pa, Max. There were about 5000 [U-47s] made, about 3200 long bodies and the rest short. London, UK, April, 2011 – Producer/engineer and performer Richard Philips, best known by his stage name Richard X, has purchased a new U47 large diaphragm microphone from US…, Engineer John Neff and Journey Purchase Two Vintage Mic Recreations Pictured (L-R) at The Plant in Sausalito are Neal Schon, Arnel Pineda, Jonathan Cain, and Deen Castronovo. Please let us know! Four of them were called the BV-08, despite differences in mounting, appearance, and construction. Omnidirectional (The U 48, introduced around 1957, was a U 47 that provided either Cardioid or Figure-of-8 patterns. Upon first glance of the new U47 from TELEFUNKEN Elektroakustik, it's easy to see the "family resemblance." It has become the most revered vocal microphone in history, and inspired dozens of attempts to recreate its sound.
