SM7B Cardioid Dynamic Microphone

Overview

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
