SM7B Cardioid Dynamic Microphone
The SM7B is a selectable frequency response microphone that delivers warm and smooth audio in close-proximity studio and vocal applications.
Optimized shielding from external electromagnetic hum, along with internal shock mounting, external windscreens and adjustable bass roll-off and midrange emphasis response settings provide clean, consistent reproduction.
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
• Rugged construction and excellent cartridge protection for outstanding reliability
