U47

The U47’s authoritative mid-range and extended low frequency response have made it the gold standard for microphones in professional recording studios around the world. The TELEFUNKEN Elektroakustik recreation delivers the famous high-fidelity tone and character that is synonymous with its name and is true to the original design. 

Sonic Characteristic

Whether you're recording a symphony, a crooner, or any facet of modern music, you'll find a great tool in the U47. Its classic mid-forward frequency response and high-fidelity sound has come to be an integral part of what makes an exceptional recording stand above the rest. Everything, from vocals to the loudest of guitar sounds, full on orchestral recording, beautiful backing vocal arrangements, or a chamber ensemble will benefit from the rich and vibrant tone of the U47. 

Circuit Design

The TELEFUNKEN Elektroakustik recreation of the U47 is electronically true to the original circuit except for the use of the VF14K, a plug-and-play replacement for the extremely rare VF14 vacuum tube. The new production U47 also features an American-made mylar M7 capsule, an American-made BV8 output transformer, premium electrolytic and polystyrene capacitors, and precision film resistors. The seemingly simple circuit showcases a perfect balance of all elements of the design, highlighting its brilliance. 

Construction

The TELEFUNKEN Elektroakustik U47 recreation is adorned in the classic styling of early, so-called “long body” U47’s; with a chrome headgrille and matte nickel-plated body. All hardware and mechanical parts are machined to vintage specifications in order to be cross compatible with original examples. The component layout and wiring scheme are nearly identical to originals, as well. The classic TELEFUNKEN Diamond logo is proudly riveted to the front of every body tube. 

Accessories

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.
