MODEL SM58

UNIDIRECTIONAL DYNAMIC MICROPHONE
OVERVIEW
The Shure SM58

is a unidirectional (cardioid) dynamic vocal
microphone designed for professonal vocal use in sound rein-
forcement 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 re-
sponse for a sound which is a world standard. Rugged construc-
tion, a proven shock mount system, and a steel mesh grille en-
sure that even with rough handling, the SM58 will perform con-
sistently. Outdoors or indoors, singing or speech—the SM58 is
the overwhelming choice of professionals worldwide.
