Shure SM11 User manual

GENERAL
The Shure Model SM11 is a miniature dynamic lavalier
microphone designed for use in television broadcasting (on
camera), for sound reinforcement, in certain radio and mo-
tion picture applications, and similar uses where a small,
professional-quality, microphone is required. The SM11 has
an omnidirectional pickup pattern, and its frequency re-
sponse is optimized for lavalier use. The microphone is sup-
plied with a tie clasp assembly, tie tack assembly, connector
belt clip, and zippered carrying/storage bag. An optional kit
for mounting the SM11 on various musical instruments is
available as Shure Model RK279.
