Description

The dBooster
In-Line Signal Booster

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 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.

RECOMMENDED APPLICATIONS

  • Miking any low-volume sound source (acoustic instruments, vocals, etc.)
  • Recording direct to a DAW interface
  • Use on long cable runs to retain sound quality

FEATURES

  • 12dB and 20dB gain stages
  • High input impedance
  • Low output impedance
  • Rugged case construction
  • Ultra-low noise performance
  • Ultra-low distortion
  • Wide frequency bandwidth

BENEFITS

  • Safe for use on all ribbon mics
  • Increases headroom at the preamp
  • Provides true electrical isolation
  • Protects ribbon mics from phantom-power
  • Minimizes mic loading
  • Capable of driving difficult loads, such as mic splitters and vintage style preamps, without increased distortion or loss of gain
