I have seen videos of Elvis Presley and other performers in Las Vegas from the 1970s. Some are using wireless mics that appear to be Shure. What is the story?
Shure did not offer wireless mic systems in the 1970s. However, Shure mic elements were sold to the major manufacturers for wireless mics in the 1970s: HME, Swintek, Vega, and Edcor.
Shure offered a wireless mic system in the early 1950s called the Vagabond. By 1956 it was discontinued. Shure re-entered the wireless microphone market in 1988 with the W Series.
