Shure SM7dB Active Cardioid Dynamic Broadcast Microphone

Loud and clear! Awesome on vocals and more, this cardioid dynamic mic delivers the Shure SM7B sound you know and love, plus a switchable +18/+28 dB boost.

The SM7dB is a cardioid dynamic microphone with a Shure-designed built-in preamp providing up to +28 dB of low-noise, flat, transparent gain ideal for lower-output interfaces and simplified audio chains. Delivers warm and smooth audio for vocal and studio applications. Preamp bypass switch, adjustable bass roll-off and presence boost, electromagnetic hum shielding, internal shock mounting, and external windscreen ensure clear and consistent audio reproduction.


- Built-in active preamp providing either +18dB or +28dB of extra gain delivers levels suitable for any interface.
- Flat, wide-range frequency response for exceptionally clean and natural reproduction of both music and speech.
- Preamp bypass switch to revert to original SM7B performance.
- Bass roll-off and mid-range emphasis (presence boost) EQ switch controls.
- Superior 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.
- 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.
