Shure SM89 Shotgun Microphone
Shure SM89condenser shotgun microphone can be used for theater sound reinforcement, spot news coverage, or wildlife recording, thanks to its distant pickup characteristics suitable for on-location film and television production. The SM89 discriminates at a distance in favor of desired dialogue or effects and against ambient noise, even in noisy surroundings.The SM89's on-axis frequency response is very smooth an 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 is virtually free of comb-filter effects. This is important when it is impossible to aim the mic precisely or when it is desirable to pick up dialogue or sound from moving sources. Features
