{"product_id":"shure-sm7db-open-box","title":"Shure SM7dB Dynamic Vocal Microphone with Built-In Preamp (Open Box, Brand New)","description":"\u003cp\u003eThe SM7dB is the modern evolution of the legendary SM7B, featuring a custom Shure-designed built-in active preamplifier that provides up to +28 dB of clean gain. This eliminates the need for external gain boosters like the Cloudlifter, making the SM7dB work effortlessly with any XLR interface while preserving the iconic SM7 sound character. A bypass switch reverts the microphone to original SM7B passive performance.\u003c\/p\u003e\n\n\u003ch3\u003eBuilt-In Preamp\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGain settings:\u003c\/strong\u003e +18 dB, +28 dB, or Bypass (original SM7B mode)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePreamp noise floor:\u003c\/strong\u003e -130 dBV equivalent input noise (A-weighted)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePower:\u003c\/strong\u003e 48V phantom power required when preamp is engaged; no power needed in bypass mode\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutput impedance:\u003c\/strong\u003e 27 ohms (preamp active) \/ 150 ohms (bypass)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSound and Shielding\u003c\/h3\u003e\n\u003cp\u003eThe same flat, wide-range frequency response as the SM7B, preserved identically at all gain settings.
