MODEL SM89
CONDENSER SHOTGUN MICROPHONE
Model SM89 is a highly directional condenser shotgun
microphone with distant pickup characteristics suitable for
on-location film and television production. The SM89 can
also be used for theater sound reinforcement, spot news
coverage, or wildlife recording. The SM89 discriminates at
a distance in favor of desired dialogue or effects and
against ambient noise–even in noisy surroundings.
The on-axis frequency response of the SM89 is very
smooth and extended. For clarity and speech intelligibility,
a slight presence rise optimizes the high-frequency re-
sponse to compensate for high-frequency losses. A low-
frequency roll-off minimizes pickup of wind, mechanical
vibration, ambient noise, and rumble without affecting
voice frequencies.
The off-axis response of the SM89 is virtually free of
comb-filter effects. This is important when it is not possible
to aim the microphone precisely or when it is desirable to
pick up dialogue or sound from moving sources.
