Shure microphone serial number dating

Several variants of the original Unidyne have been produced, most notably the 55S or "Baby Unidyne." The 55S is sometimes referred to as the "Elvis mic" due to its frequent use by Elvis Presley, and is the microphone depicted with Elvis on the commemorative first-class Elvis stamp issued by the U. Produced since 1965 and still in production today, it has been widely used in many applications, including micing vocals, drums, and guitar amplifiers both in live sound and recording applications, including being used by every United States President from Lyndon Baines Johnson on.It was used by Michael Jackson when recording the lead vocals for the song "Billie Jean." Together, the Shure SM57 and SM58 have been the two bestselling microphones in the world since the late 1960s.

By 1928, the company had grown to over 75 employees, and Sidney's brother, Samuel J.Shure, joined the company, which was renamed Shure Brothers Company.The company moved into new offices at 335 West Madison Street in Chicago. In 1931, Shure and engineer Ralph Glover began development of the first Shure microphone, and the following year, the Model 33N Two-Button Carbon Microphone was introduced, making Shure one of only four microphone manufacturers in the U. Shure's first condenser microphone, crystal microphone, and microphone suspension support system (for which they received their first patent) were all introduced that same decade.In 1929, with the advent of the Great Depression and the increased availability of factory-built radios, Shure Brothers Company was forced to greatly reduce their staff and became the exclusive US distributor of a small microphone manufacturer. In 1939, Shure introduced the Model 55 Unidyne Microphone, which went on to become one of the world's most recognized microphones. Shure also manufactured throat, headset, and oxygen mask microphones, and adopted the United States Military Standard for all Shure microphones. Among Shure's innovations in phonograph cartridge design was Ralph Glover and Ben Bauer's "needle-tilt" principle for minimizing record wear while improving sound reproduction, and Jim Kogen's engineering concept of "trackability." Shure produced the first phonograph cartridge capable of playing both long-playing and 78 rpm records, the first cartridge with tracking force of only one gram, and the first cartridge meeting the requirements of stereo recording.In 1941, Shure was contracted by the United States armed forces to supply microphones during World War II, and by the following year, the T-17B was the microphone most widely used by the U. By the mid-1940s, Shure was also manufacturing and supplying phonograph cartridges to major phonograph manufacturers including Philco, RCA, Emerson, Magnavox, Admiral, and Motorola, and was the largest producer of phonograph cartridges in the U. At the peak of Shure's phonograph cartridge production, the company was producing approximately 28,000 cartridges per day, with 25,000 of those coming from a Shure phonograph cartridge plant in Phoenix, Arizona.In 1981, James Kogen, Executive Vice President, Operations, was promoted to President and General Manager of Shure. In 1996, James Kogen retired; Santo (Sandy) La Mantia, Vice President of Engineering, was named President and CEO.

Shure Brothers Incorporated was officially renamed Shure Incorporated in 1999.

One of Shure's most visually iconic microphone series is the Unidyne series, seen in use by heads of state and popular recording artists and performers from the 1940s through the end of the twentieth century, including President John F. delivering of his I Have a Dream speech during the 1963 March on Washington. Shure also designed the T-30 Throat Microphone for flight crews.

The original Shure 55 Unidyne microphone was designed by engineer Ben Bauer and first produced in 1939. Shure's adoption of the Military Standard Specification, and product redesigns intended to conserve raw materials essential to the war effort, positioned the company to fulfill the military's needs for specialized microphones. A cloth strap held the T-30 against the throat, capturing the user's voice box vibrations directly and avoiding the background noise of the airplane. lookout Private Lockhard used a Shure 700A microphone to announce his sighting of Japanese planes approaching Pearl Harbor on the morning of On December 7, 1941.

Their feature set is nearly identical, with the main difference between the two being their different grilles.

Shure later expanded the SM series, which now includes such models as the SM58, SM48, SM86, SM87A, SM57, SM94, and SM81. These feature a supercardioid designs based on SM series microphones, but with neodymium magnet structures for higher output.

In 1937, their 66A piezoelectric stethophone was designed to accurately reproduce chest sounds, and in the early 1960s, the SP-5, SP-5S and SP-6 stethoscope pickups were produced.
