Shure SM85 Quick Start Manual

GENERAL
The Shure Model SM85 is a professional-quality,
hand-held, unidirectional condenser microphone
designed for the most demanding applications in sound
reinforcement, broadcasting and studio recording. It is
especially suitable for applications requiring wide fre-
quency response, low distortion characteristics, very
low RF susceptibility, and reliable operation over a wide
range of temperature and humidity extremes. The SM85
makes optimum use of proximity effect to give the per-
former control of low-frequency sound, from the warm
intimacy of close miking to the natural sounds of
normal-to-distant miking. The SM85 also features an in-
tegral wind and pop filter, a high-frequency presence
peak, a controlled low-frequency rolloff, and an effec-
tive shock mount for reduced stand and handling noise.
The case is constructed of aluminum for light weight
and ruggedness, with a steel grille and durable black
finish.

forcement, broadcast, or recording equipment. The Type
SM85 operates over an extremely wide voltage range of

standard.
The microphone is supplied with an accessory swivel
adapter. Model SM85-LC is supplied without a cable,
and Model SM85-CN is supplied with a 7.6m (25 ft)
TRIPLE-FLEX@ microphone cable with professional
audio connectors. Two dual-channel power supplies
;+lo
(Models PSI and PSlE2) are available for providing
simplex power to the SM85.
