Shure SM7dB Active Dynamic Microphone with +28dB Built-In Active Preamp

The SM7dB is a cardioid dynamic vocal microphone, incorporating a custom Shure-designed built in preamp with technology licensed from Cloud, tuned by Shure engineers specifically for the SM7dB. The SM7dB delivers the legendary, warm vocals of the original SM7B with the convenience of an integrated preamp offering up to +28dB of adjustable gain. The SM7dB provides a warm and velvety audio response tailored to suit nearly any vocal need, whether an independent content creator or a large-scale studio.

Shure SM7DB 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
