Every Detail from your Ribbon and Dynamic Microphones

The Royer 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 coloration. 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 Class A input circuitry presents a high source impedance to the microphone, which minimizes loading (damping). This reduces coloration and distortion while at the same time improving headroom.

By utilizing the 12/20dB gain switch, optimum balance between gain and headroom can be achieved for a variety of uses.

The low-impedance output of the dBooster is an increased microphone-level signal that can drive a digital interface directly or a standard microphone preamplifier. It also minimizes signal loss on long cable runs.

Royer R-DB20 dBooster in one take:

  • Boost the signal of your low-output ribbon or dynamic microphones
  • Capture every detail in low-level vocal and acoustic recordings
  • Retain signal quality over long cable runs
  • Protect valuable ribbon mics from phantom power
  • Small, rugged form-factor perfect for tight miking studio setups
  • Ultra low noise and distortion performance
  • Wide frequency bandwidth maintains signal integrity for any type of recording
  • Increase preamp headroom
  • True electrical isolation for your signal
  • Able to drive difficult loads like vintage preamps and mic splitters without gain loss or distortion
