The Royer model R-DB20 is a phantom-powered ribbon and dynamic microphone signal booster and impedance buffer. It increases the level of passive low-output ribbon and dynamic microphones with a minimum of distortion or colouration. Designed for professional applications, the dBooster provides two levels of clean gain boost; 12dB and 20dB, selectable by a front panel switch. The dBooster maintains headroom and gain regardless of load. The dBooster's Class A input stage delivers crystal clean gain with virtually no noise or self-distortion.

The dBooster's low-impedance output keeps things clean in the studio and also shines on live stages, driving long cable lengths and difficult loads like mic splitters and vintage-style preamps with no loss of gain, no increased distortion, and excellent headroom.
