SM89 Shotgun Microphone |

Product Code:
SM89
|
The SM89 is a highly directional condenser shotgun
microphone with distant pickup characteristics suitable for
on-location film and television production, 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.
