SM7dB Dynamic Vocal Microphone with Built-In Preamp

OVERVIEW

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.

FEATURES

• 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.

• Rugged construction and excellent cartridge protection for outstanding reliability.
