MODEL SM89
CONDENSER SHOTGUN MICROPHONE
Model SM89 is a highly directional condenser shotgun microphone
with distant pickup characteristics suitable for on-location lm
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 response 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-
lter 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.
