Shure SM7DB Dynamic Vocal Microphone with Built-In Preamp

The SM7dB is a cardioid dynamic microphone with a Shure-designed built-in preamp. It provides 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.

Highlights:

• 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.

• 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.
