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-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.
