KCOR Microphone


This model 55 Shure microphone was used at the KCOR-AM radio building in San Antonio, Texas during the 1950s. First introduced in 1939, the microphone became iconic due to its adoption by radio personalities and musical acts. The microphone uses Shure’s “Unidyne” element, a pick-up element that only accepts sounds from one direction and forms a cardioid sensitivity pattern. KCOR was licensed and operated by Raoul A. Cortez (1905-1971), a pioneer of Spanish-language media in the United States. Cortez later established the KCOR-TV station in 1955, and programmed his stations to serve the Spanish-speaking community in Texas.
