A true legend
The U47 from TELEFUNKEN Elektroakustik has a clear “family resemblance” to the original. The large, chrome main grille houses the newly manufactured M7 capsule. Its matte nickel finish body houses a new BV8 output transformer and the newly developed VF14k vacuum tube; a “plug and play” replacement for the rare VF14M tubes found in the original.
The classic “TELEFUNKEN” diamond logo adorns the front. Since its original development in 1946, the TELEFUNKEN U47 has been the microphone of choice for generations of artists and professionals. The first condenser microphone to offer selectable character (kidney and ball). The original U47 also contained the famous M7 capsule, the M7 was 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 sound quality that was absolutely unheard of in the English-speaking world in the mid-1940s, where ribbon microphones had been the standard for many years. The introduction of the U47 brought a new level to the audio world and it is still considered to be one of the finest microphones ever produced. Whether you’re recording a symphony, a “crooner” or any other facet of modern music, you’ll find a great tool in the U47. The incredible tone and “deliciousness” of this microphone is legendary and will delight every source.
The U47 microphone system comes complete with M940 power supply, M840 25, ACX-7 tube microphone cable, M740 elastic shock mount, FC40 flight case with locks, and WB40 wooden microphone box.
