The Shure SM7B Vocal Microphone is a dynamic microphone with a smooth, flat, wide-range frequency response appropriate for music and speech in all professional audio applications.
It features a cardioid polar pattern, bass roll-off and midrange emphasis (presence boost) controls, and shielding against broadband interference. An internal air suspension shock isolation helps to eliminate mechanical noise transmission, and a yoke mount facilitates mounting and provides precise control of the mic position.
Cardioid polar pattern effectively isolates signal source improving gain before feedback.
