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 motion
picture applications, and similar uses where a small,
professional-quality, microphone is required. The SM11 has an
omnidirectional pickup pattern, and its frequency response is
optimized for lavalier use. The microphone is supplied 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.
