Neighbor effect:When the sound source and the distance from the microphone for less than 6 mm, the microphone audio to improve the low (100 Hz to raise the 6-10 db), so that low-Audio microphone distance to be more than the simple and honest warmth. This effect is called neighbor effect, and only such as the SM57 dynamic microphone can be created out of orientation. SM57 low-frequency attenuation characteristics make full use of user-friendly neighbor effects, and better control of sound.Technical Specifications:Type: Dynamic Frequency response: 40 to 15,000 Hz Polar point features: directional (heart-shaped), around the microphone axis of rotation, and symmetry, the frequency uniform.
