General Description

The Shure SM57 unidirectional dynamic microphone is exceptional for musical instrument pickup or for vocals. With its bright, clean sound and carefully contoured presence rise, the SM57 is ideal for live sound reinforcement and recording. It has an extremely effective cardioid pickup pattern which isolates the main sound source while minimizing background noise. In the studio, it is excellent for recording drums, guitar, and woodwinds. For musical instruments or vocals, the SM57 is a consistent choice of professional performers.

Placement

General Rules for Use

• Aim the microphone toward the desired sound source (such as the talker, singer, or instrument) and away from unwanted sources.
• Place the microphone as close as practical to the desired sound source.
• Work close to the microphone for extra bass response.
• Use only one microphone to pick up a single sound source.
• Use the fewest number of microphones as practical.
• Keep the distance between microphones at least three times the distance from each microphone to its source.
• Place microphones as far as possible from reflective surfaces.
• Add a windscreen when using the microphone outdoors.
• Avoid excessive handling to minimize pickup of mechanical noise and vibration.
• Do not cover any part of the microphone grille with your hand, as this will adversely affect microphone performance.

Note: The grille on top of the microphone should rotate freely. This is part of the design and does not mean the grille is broken. In certain applications (such as close-miking drums) an audible rattle might occur. A windscreen or a very small piece of foam wedged under the grille can eliminate this problem, but do not apply tape or otherwise cover or block the grille vents, as this disrupts the directionality of the microphone. Please visit the Shure website for more information.

The following table lists the most common applications and placement techniques. Keep in mind that microphone technique is largely a matter of personal taste; there is no one "correct" microphone position.
