SM57s

The SM57 is a dynamic microphone, originally designed by Shure Inc. for use in live sound reinforcement. It is one of the most popular microphones in the world, known for its versatility and reliability. The SM57 is a large-diaphragm, moving-coil dynamic microphone that operates on the principle of electromagnetic induction.

The microphone features a 1.25-inch (32 mm) aluminum diaphragm, which is suspended in a steel capsule. The capsule is filled with a gas to reduce distortion and improve frequency response. The SM57 has a cardioid polar pattern, which means it is most sensitive to sounds directly in front of it and rejects sounds from the sides and rear. This makes it well-suited for vocal and instrument amplification.

The SM57 is known for its warm, full sound, which is achieved through its frequency response. It has a relatively flat response in the midrange, with a slight roll-off at the high and low ends. This response is suitable for a wide range of applications, from vocals to drums and guitars.

One of the key features of the SM57 is its robust build. It is designed to withstand the rigors of live performance, with a metal mesh grille that protects the diaphragm from damage. The microphone also has a robust XLR connector, which is designed to withstand the vibrations and impacts of live performance.

The SM57 is available in several different versions, including the SM57-LC, which has a larger, more robust diaphragm, and the SM57-V, which has a built-in pop filter. There is also the SM57-TS, which is a wireless version of the microphone.

The SM57 has been used by countless musicians and bands over the years, including The Rolling Stones, The Beatles, and Elvis Presley. Its popularity is due in part to its affordability and the fact that it has been used on many iconic recordings.

In summary, the SM57 is a versatile and reliable dynamic microphone that has become a staple in the world of live sound reinforcement. Its warm, full sound and robust build make it a popular choice for a wide range of applications.
