THE SOUND OF THE PROFESSIONALS@

PROFESSIONAL PRODUCTS

GENERAL

The Shure Model SM80 is a high-quality, omnidirec-

tional condenser microphone designed for the most
demanding professional applications in studio record-
ing, broadcasting and sound reinforcement. It is
especially suitable for applications requiring extremely
wide frequency response, low noise and distortion
characteristics, very low RF susceptibility, and reliable
operation over a wide range of temperature and humid-
ity extremes. The SM80 features a selectable 10 dB

attenuator and a three-position low-frequency response
switch. The case is constructed of steel for ruggedness,
with a stainless steel screen, and finished in durable
vinyl paint.

The SM80 is designed for phantom (simplex) power-

ing from an external supply such as the Shure Model
PS1A, or directly from recording, broadcast or sound
reinforcement equipment. The SM80 operates over a

wide voltage range covering both DIN Standard 45 596
phantom voltages of 12 and 48 volts.

The microphone is supplied with a highly efficient

pop filter grille (Model A81G), attenuator lock, and
swivel adapter. Also available for use with the SM80 are
a unidirectional microphone cartridge (Model R104), a
heavy-duty windscreen (Model A81WS), and a compact,
lightweight microphone stand (Model S15) capable of
being extended to 4.3m (14 ft). A dual-channel power
supply (Model PS1A) is available for providing phantom
power to the SM80.
