Telefunken U-47

Since its original development in 1946, the TELEFUNKEN U-47 Condenser Microphone has been the microphone of choice for generations of recording professionals.

The first condenser microphone to offer selectable polar patterns (cardioid and omni), the original Telefunken 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 VF-14 tubes (they had been used in field and aircraft radios), and BV8 output transformer.

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.

The telefunken U-47's matte nickel finished body houses a new BV8 output transformer and a new VF-14k vacuum tube; a "plug and play" replacement for the rare VF-14M tubes found in the original. The classic "TELEFUNKEN" diamond logo proudly adorns the front of the body tube. All of these accoutrements show that this microphone means business.
