Lapel Microphone (LM-835) is a small capsule
microphone with a spring clip for securing it on to
a clothing edge. The lapel microphone renders
excellent vocal reproduction. The lapel microphone
is less obtrusive to the user and least visible.
However, due the greater distance from mouth to
microphone it will require additional gain. As a
result it is more prone to feedback. So adjustment
of volume is more critical, especially near or under
a speaker.
