The Neumann U47 set the sound of the studio

The German valve microphone appeared in 1947 and defined the vocal sound Georg Neumann's U47 used a large dual-diaphragm capsule and a valve circuit with an output transformer, giving a warm low end and a lift in the upper mids. It can switch between cardioid and omnidirectional patterns remotely. Original examples are rare, and modern reissues copy the circuit closely. It sits in Mondo's music collection, one of 200 facts that each trace back to the reference below.
