The Shure Model 525 omnidirectional moving coil dynamic – The 1954 Product Data Sheet describes this microphone as “a slender, moving-coil dynamic microphone, custom-built to provide high-fidelity reproduction of voice and music as well as features an omnidirectional pattern.
The microphone is versatile and reliable for both indoor and outdoor use. The extended, smooth frequency response and the attending faithful reproduction are largely due to a newly designed diaphragm attached to a sensitive coil suspended in a magnetic structure.
The use of high-efficiency magnetic materials and specially designed magnetic circuits has made it possible to develop this small microphone and still achieve maximum operating efficiency. The microphone is ruggedly built to withstand hard usage and is unaffected by temperature and humidity variations.”
Shure SM53 and SM54 – The SM53 and SM54 were internally the same, with the SM54 having a larger grille.
According to the 1970 Product Data Sheet, “the reliable performance, outstanding features, and handsome appearance of the SM53 and SM54 make them extremely versatile and ideally suited for many demanding applications in television, radio, recording, motion pictures, and sound reinforcement. The performance and appearance of the two models are very similar; however, the SM54 is specifically designed for use in very difficult close-talking and hand-held situations because of its immunity to “pop” and breath blasts.” Elvis used these microphones in the 1970s, primarily because they had little bass build-up from the proximity effect. The deep voice of Elvis did not require “more bass.”
“Elvis” is now playing in theaters nationwide.
