Shure SM7DB ACTIVE DYNAMIC MICROPHONE

Shure SM7dB Vocal Microphone with Built-In Preamp

The Shure SM7dB delivers the exact same legendary, warm, and smooth vocal tone that has made the original SM7B a global icon in broadcasting, podcasting, and studio tracking—now upgraded with a game-changing, built-in Shure-designed active preamp. By eliminating the need for an external inline signal booster, this high-performance dynamic microphone guarantees pristine, broadcast-ready gain with any standard XLR audio interface, making it an ultimate asset for modern content creators, streamers, and recording studios.

Key Features & Technical Specifications:

• Built-In Active Preamp: Say goodbye to low-signal struggles. The integrated, custom-voiced preamp provides either +18 dB or +25 dB of transparent, discrete gain, completely optimizing your signal-to-noise ratio and allowing you to plug directly into any standard XLR interface without a cloud lifter or external booster.
• True Bypass Mode: Want the pure, original circuit? A convenient hardware switch lets you completely bypass the internal preamp, reverting the microphone back to a standard, passive SM7B with its classic $-59\text{ dB}$ sensitivity—perfect for cranking high-gain guitar cabs or loud snare drums.
• Iconic Flat, Wide-Range Frequency Response: The SM7dB preserves the celebrated cartridge design of its predecessor, delivering exceptionally clean, natural reproduction of both music and speech. It features an ultra-smooth $50\text{ Hz}$ to $20\text{ kHz}$ range that tames harsh sibilance and highlights vocal warmth.
• Advanced Hardware Tone Sculpting: Tailor your acoustic footprint on the fly using the rear-panel passive controls. Engage the Bass Rolloff switch to eliminate low-end room rumble and muddy proximity effect, or toggle the Presence Boost to add crisp, mid-range articulation that cuts through any dense audio mix.
• Elite Electromagnetic Shielding: Engineered with internal humbucking protection, the microphone actively rejects electromagnetic hum generated by computer monitors, neon studio lighting, and nearby audio hardware, ensuring your recordings remain entirely hum-free.
• Internal Air Suspension Shock Isolation: A built-in mechanical shock isolation system virtually eliminates the transmission of handling noise, desk vibrations, and physical thumps, giving you total freedom of movement on a boom arm.
• Integrated Pop Filter & Custom Windscreens: The iconic capsule design features an optimized pop filter to defeat plosives ($P$ and $B$ sounds) without requiring an external screen. It ships with both a standard windscreen and a detachable close-talk windscreen for intimate podcasting and streaming layouts.
• Heavy-Duty Swivel Yoke Mount: The rugged, captive stand nut allows for precise positioning control, letting you securely mount, tilt, and lock the microphone at the perfect ergonomic angle on any standard microphone stand or studio boom arm.
