The SM7B dynamic microphone has a smooth, flat, wide-range frequency response appropriate for music and speech in all professional audio applications. It features excellent shielding against electromagnetic hum generated by computer monitors, neon lights, and other electrical devices. The SM7B has been updated from earlier models with an improved bracket design that offers greater stability. In addition to it's standard windscreen, it also includes the A7WS windscreen for close-talk applications.
Features
Flat, wide-range frequency response for exceptionally clean and natural reproduction of both music and speech
Bass rolloff and mid-range emphasis (presence boost) controls with graphic display of response setting
Improved rejection of electromagnetic hum, optimized for shielding against broadband interference emitted by computer monitors
Internal "air suspension" shock isolation virtually eliminates mechanical noise transmission
Highly effective pop filter eliminates need for any add-on protection against explosive breath sounds, even for close-up vocals or narration
Now shipping with the A7WS detachable windscreen, designed to reduce plosive sounds and gives a warmer tone for close-talk vocals
Yoke mounting with captive stand nut for easy mounting and dismounting provides precise control of microphone position
Classic cardioid polar pattern, uniform with frequency and symmetrical about axis, to provide maximum rejection and minimum coloration of off-axis sound
