Since its original development in 1946, the TELEFUNKEN U47 has been the microphone of choice for generations of recording professionals. 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. 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 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. 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.

Upon first glance of the new U47 from TELEFUNKEN Elektroakustik, it's easy to see the "family resemblance." The large, chrome head grille houses a newly manufactured M7 capsule. 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. 

Each U47 microphone comes complete with M 940H power supply, M840TH 25’ Sommer tube microphone cable, M740 shock mount, FC40 locking flight case and WB40 wooden microphone box.
