GENERAL
The Shure SM77 STARMAKER™ microphone is a
small, lightweight, extremely rugged dynamic unit with
a cardioid (unidirectional) pickup pattern and a smooth,
wide frequency response. The microphone is available
in ebony vinyl enamel finish.
Because of the feedback rejection of the SM77 car-
dioid pickup pattern, the microphone is suitable for
sound reinforcement applications or other uses where
room acoustics or ambient noise is a problem as well as
for handheld or stand mounted use in broadcast and
recording studios. The microphone can be used for
voice or instrument pickup, and for closeup vocals with
the pop protection of the accessory windscreen.
The microphone has a tailored low-frequency rolloff
and a gentle mid-frequency presence peak to enhance
intelligibility of speech and singing.
The SM77 microphone is supplied as Model SM77EB-
LC, ebony vinyl enamel finish, without
a
cable. The unit
is supplied with a Model A25B Swivel Adapter.
For superior wind and pop protection, when used out-
doors or for closeup vocals, an accessory windscreen is
available as Model A2WSA-BK. Also recommended is
the Shure C25E, a 7.6m (25 ft) TRIPLE-FLEX
®
two-
conductor shielded cable with 3-pin XLR audio connec-
tors; the microphone connector is finished in black to
complement the SM77.
