Royer Labs R-DB20 dBooster
- True Class-A input stage
- Extreme RF protection
- Crystal clear gain with virtually no noise or self-distortion
- Enormous amount of headroom – will not break up!
- Low impedance output handles splitter cables and long cable runs beautifully
Product information "Royer Labs R-DB20 dBooster"
The dBooster features two selectable gain settings (12 dB or 20 dB) so you can choose just the right amount of clean boost for different microphones and instruments.
A low-impedance output allows it to drive long cable runs, mic splitters, or demanding loads without loss of gain, added distortion, or compromised headroom
It is safe for ribbon microphones (phantom voltage is not passed through to the mic) and helps preserve mic performance by minimizing loading and distortion.

The Royer model R-DB20 is a phantom-powered ribbon and dynamic microphone signal booster and impedance buffer. It offers a clean signal boost for passive low-output ribbon and dynamic microphones. Designed for professional applications, the dBooster provides two levels of clean gain boost; 12 dB or 20 dB, selectable by a front panel switch.
Circuit / internal design: The dBooster design starts with a differentially configured input stage consisting of multiple paralleled PNP semiconductors for low noise performance. These semiconductors run in pure Class A for minimal distortion.
The output section uses a pair of operational amplifiers that act as buffers / low-impedance line drivers. The output stage enables the dBooster to drive difficult loads without sacrificing gain or performance while maintaining excellent headroom.
Power is derived from 48 V phantom power, but internally regulated and decoupled, ensuring clean voltage and current for optimum operation.
Warranty / Build Info: The dBooster is covered by a one-year bumper-to-bumper warranty (parts & labor) (but excluding damage from misuse).
