Get to know them!

Perfect for power-hungry dynamic and ribbon microphones, Royer’s dBooster2 delivers more than double the utility of the original dBooster with a dual-channel design and flexible DI functionality. This studio-grade in-line booster simultaneously injects up to two ribbon mics or dynamics mics with a crystal-clear, switchable 12/20dB dose of gain, allowing you to record even the lowest-level sources with stunning clarity. Picky about signal noise? No problem — the dBooster 2’s massive headroom, noise-free operation, and exemplary RF protection elevate your signal and ensure optimal, distortion-free sound in any application. Moreover, the dBooster2’s premium circuitry — which includes a true Class-A input stage — keeps your microphones’ sound as natural and uncolored as possible. It’s all finished off with dual combo XLR jacks, allowing the dBooster2 to double in function as a DI with an 8dB boost for straight-in guitar and bass recording. Designed to excel in professional studios, live sound scenarios, or even bedroom podcast recording sessions, the Royer dBooster2 takes your ribbon mics, dynamic mics, and instrument-level signals 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 dBooster2 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 dBooster2 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 dBooster2’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 dBooster2 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. What’s more, the dBooster2’s combo XLR jacks allow this device to double in function as a rock-solid DI for instrument-level sources — you even get an 8dB boost on the DI to kick up your guitar or bass guitar’s signal even further! Best of all, the dBooster2’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 dBooster2’s premium design maintains headroom and gain regardless of load. The dBooster2’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.
