THE SOUND OF THE
The Model SM82-LC is a hand-held, self-contained,
unidirectional, condenser microphone containing its
own line level amplifier, peak limiter, and battery. It is
designed to provide a line level output for use in a varie-
ty of broadcasting situations where a line level
microphone with a built-in limiter is required.
Microphone Features:
Wide range frequency response for exceptionally
