Our foray into the world of Professional Audio began in 1931 with the addition of Shure Brothers. While Shure Brothers initially made radio kits, it was not long before they moved into the world of microphones. The Professional Audio division truly took form with the addition of Peter Schmitt in 1957. Having recently retired from the Marine Corps as a Captain, his degree in Electrical Engineering and love of music made joining the family business an easy decision. During the next 25 years, Shure Brothers moved further into the professional world with the introduction of the SM line, wireless, circuitry, and speakers. In addition, The Peter E. Schmitt Company began to add lines such as Amphenol, Aphex, Omnimount, Rane, and Bose.
