Functioning more like the front end of a high-end preamplifier than a standard lifter, it utilizes a true Class-A input stage to deliver crystal-clear, uncolored gain via standard 3-pin XLR connections. The unit offers two switchable levels of clean boost—12dB or 20dB—allowing users to tailor the signal strength to their specific source and preamp requirements. By providing a high input impedance, it prevents the \"loading\" effects that can dull the high-frequency response of sensitive ribbon mics, ensuring they sound open, natural, and detailed.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003eBuilt for professional reliability, the dBooster is housed in a rugged chassis and provides complete electrical isolation, protecting delicate ribbon elements from phantom power while utilizing that same 48V power to operate its own internal circuitry. Its low-impedance XLR output is designed to drive difficult loads effortlessly, making it an ideal solution for long cable runs or when using mic splitters without signal degradation. Whether used in the studio to capture whisper-quiet vocals or on stage to drive long lines, the dBooster maintains massive headroom and virtually zero self-distortion, bringing new life to classic microphones like the Royer R-121 or Shure SM7B.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eClass-A Input Stage\u003c\/b\u003e – Delivers ultra-low noise and pristine audio quality indistinguishable from high-end preamps.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eSwitchable Gain\u003c\/b\u003e – Front-panel switch allows you to select between 12dB or 20dB of clean, transparent boost.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eXLR Connectivity\u003c\/b\u003e – Features standard balanced 3-pin XLR input and output for universal microphone compatibility.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eHigh Input Impedance\u003c\/b\u003e – 3.6k-ohm input prevents mic loading, preserving transient response and high-frequency clarity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eRibbon Protection\u003c\/b\u003e – Internally decoupled design isolates the microphone from phantom power to keep ribbons safe.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eLoad Driving\u003c\/b\u003e – Low-impedance output handles long cable runs and mic splitters without signal loss or distortion.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSpecifications\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eGain:\u003c\/b\u003e 12dB or 20dB (Switchable)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eConnections:\u003c\/b\u003e Balanced 3-Pin XLR (Input and Output)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eInput Impedance:\u003c\/b\u003e 3.6k Ohms\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eOutput Impedance:\u003c\/b\u003e 300 Ohms (at 20dB setting)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eFrequency Response:\u003c\/b\u003e 20 Hz – 20 kHz (±0.25dB)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eTHD+N:\u003c\/b\u003e 0.001% (at 12dB setting)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003ePower Requirements:\u003c\/b\u003e 48V Phantom Power\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eDimensions:\u003c\/b\u003e 3.62\" x 2.0\" x 1.62\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eWeight:\u003c\/b\u003e 6 oz\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eSKU:\u003c\/b\u003e R-DB20\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Royer","offers":[{"title":"Default Title","offer_id":42967930798146,"sku":"R-DB20","price":209.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0582\/8925\/files\/medium_09247327-8849-4682-a07d-8bd0b399cef9.jpg?v=1770237054","url":"https:\/\/sweetheartdeals.com\/products\/royer-labs-dbooster-in-line-ribbon-dynamic-signal-booster-r-db20","provider":"Sweetheart Deals","version":"1.0","type":"link"}
