The phrase “vintage microphone” usually prompts images of a beveled, rectangular device with a radio or TV station's call letters emblazoned on its top or side. These are the big mics Bing Crosby sang into, or that Orson Welles and his Mercury Theatre on the Air used to scare the bejeezus out of millions of people with their broadcast of "The War of the Worlds" on October 30, 1938. Microphones, good ones anyway, make things real.
In fact, realism is exactly what a German electrical engineer named Georg Neumann was striving for when he came out with his bottle-shaped CMV3 condenser microphone in 1928. In 1932 he upgraded the mic by releasing the CMV3a, which allowed users to swap out the mic’s heads to pick up sounds from a single-direction (as in a cardioid microphone), two-directions (sometimes called figure-8s) and all directions (omni). After World War II, Neumann rebuilt his Berlin factory and by 1949 he’d released the U47, which was distributed internationally by Telefunken and favored by recording engineers throughout the 1950s and ’60s. Artists as varied as Frank Sinatra and The Beatles used the U47 in the recording studio.
While Neumann was pushing microphone technology in Europe, RCA was doing the same in the United States, especially during the 1930s, the golden era of radio, when it released a number of bi-directional ribbon microphones, including the Photophone and Velocity models. These ribbon microphones take their name from the .0001-inch thick piece of corrugated aluminum (the ribbon) that’s placed between the ends of a horseshoe-shaped magnet. Another iconic ribbon microphone of the prewar period was the BBC-Marconi Type A, which was designed by a BBC technician named Dr. Alexander and manufactured by Marconi’s Wireless Telegraph Co. of London.
