Royer R-DB20 dBooster In-Line Signal Booster

The Royer R-DB20 dBooster is an extremely compact phantom-powered In-Line Signal Booster for Passive Ribbon and Dynamic Microphones. The R-DB20 supplies all non-phantom-powered Microphones with additional Gain before the actual pre-amp stage. Covered in a robust steel enclosure, it enables additional amplification of 12dB or 20dB (switchable), while providing low noise and distortion thanks to Class-A circuitry. Impedance of the R-DB20 is 3.6kΩ, which is higher than usual for many pre-amplifiers and therefore better suited for Ribbon Microphones.

The main features of the Royer R-DB20 dBooster include:

  • In-Line Signal Booster
  • 20Hz-20kHz Frequency Response
  • +48V Phantom Powered
  • Balanced XLR Inputs & Outputs
  • Gain: 12dB/20dB (Switchable)
  • Impedance: 3.6kΩ
  • Consumption: 5mA (0) & 7.5mA (Full)
  • Manufacturer No.: R-DB20
  • Dimensions (LxWxH): 92 x 51 x 41mm
  • Weight: 170g
