The Shure SM58® is a unidirectional (cardioid) dynamic vocal microphone for professional vocal use in sound reinforcement and studio recording. A highly effective, built-in, spherical filter minimizes wind and breath “pop” noise. A cardioid pickup pattern isolates the main sound source while minimizing unwanted background noise. The SM58 has a tailored vocal response for a sound which is a world standard. Rugged construction, a proven shockmount system, and a steel-mesh grille ensure that even with rough handling, the SM58 will perform consistently. Outdoors or indoors, singing or speech, the SM58 is the overwhelming choice of professionals worldwide.
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.
|Application||Suggested Microphone Placement||Tone Quality|
|Vocals||Lips less than 15 cm (6 in.) away or touching the windscreen, on axis to microphone.||Robust sound, emphasized bass, maximum isolation from other sources.|
|15 to 60 cm (6 in. to 2 ft.) away from mouth, just above nose height.||Natural sound, reduced bass.|
|20 to 60 cm (8 in. to 2 ft.) away from mouth, slightly off to one side.||Natural sound, reduced bass and minimal “s” sounds.|
|90 cm to 1.8 m (3 to 6 ft.) away.||Thinner, distant sound; noticeable levels of ambient noise.|
Place the microphone so that unwanted sound sources, such as monitors and loudspeakers, are directly behind it. To minimize feedback and ensure optimum rejection of unwanted sound, always test microphone placement before a performance.
Unidirectional (cardioid) microphones progressively boost bass frequencies by 6 to 10 dB below 100 Hz when the microphone is at a distance of about 6 mm (1/4 in.) from the sound source. This phenomenon, known as proximity effect, can be used to create a warmer, more powerful sound. To prevent explosive low frequency sound during close-up use, the bass response gradually rolls off. This provides greater control and helps the user take advantage of proximity effect.
