Boost Your Ribbon and Dynamic Mics with up to 20dB of Pristine Gain
Ribbon mics and dynamic mics are essential tools for any well-rounded studio. Still, they come with one major caveat: they’re power hungry and often require a significant amount of gain to capture low-level sources. The Royer dBooster represents a perfect in-line solution to your low-level woes, injecting ribbon mic and dynamic mic signals with a crystal-clear, switchable 12/20dB dose of gain. This phantom-powered signal booster boasts a massive amount of headroom, exceptionally noise-free operation with essentially zero self-distortion, and exemplary RF protection, elevating your signal and ensuring optimal sound when driving long cable runs. Moreover, the dBooster’s premium circuitry — which includes a true Class-A input stage — keeps your microphones’ sound as natural and uncolored as possible. Designed to excel in professional studios, live sound scenarios, or even bedroom podcast recording sessions, the Royer dBooster takes your ribbon mics and dynamic mics to an entirely new level of performance.

Juice up your most power-hungry mics
Ribbon mics and dynamic mics are standard issues across recording and live environments, from at-home podcast recording to the world’s most revered studio settings. However, they need far more power than your typical phantom-powered condenser microphone, often requiring more juice than most audio interfaces and preamps can dish out — especially if you’re recording low-level sources like acoustic guitars, speech, and hushed vocals. Fortunately, Royer’s dBooster transforms any audio interface or preamp into a ribbon-ready powerhouse, utilizing an active phantom-powered circuit that doubles (or even quadruples!) your mic’s output with a switchable 12/20dB boost of crystal-clear gain. Lastly, because the dBooster requires phantom power to function, it also protects phantom power from reaching and potentially damaging your treasured ribbon microphones.


A multipurpose in-line powerhouse
While Sweetwater’s recording pros champion the dBooster’s ability to juice up ribbon and dynamic mics, the truth is this mighty tool offers a multitude of uses in any sonic setting. The dBooster is perfect for driving even the longest of cable runs up onstage and accommodating difficult loads such as vintage-style preamps and mic splitters without batting an eye. Best of all, the dBooster’s utterly transparent operation all but eliminates unwanted coloration, noise, and increased distortion.
High-performance and load-agnostic operation
Engineered to deliver studio-grade sonic performance, the Royer dBooster’s premium design maintains headroom and gain regardless of load. The dBooster’s Class A input circuitry presents a high source impedance to the microphone, which minimizes damping (loading). This reduces coloration and distortion while simultaneously maximizing headroom. Furthermore, you can achieve an optimal balance between gain and headroom for a variety of uses by utilizing the 12/20dB gain switch.
