Add A Multipurpose Utility To Your Signal Chain With The Royer 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

BENEFITS

  • Safe for use on all ribbon mics
  • Increases headroom at the preamp
  • Provides true electrical isolation

  • THD+N: @ 20dB Gain = .0015%, -25dBu input signal, 1.3Vp-p output signal; @ 12dB Gain = .001%, -6Bu input signal, 3.66Vp-p output signal
  • IM Distortion: @ 20dB setting, < .002% @ 800mV output, @ 12dB setting, < .005% @ 2.6volts output
  • Self-Noise: referred to -48dB re. 1V/pa, 20dB setting < 11dBa, 12dB setting < 15dBa
  • Headroom: referred to -48dB re. 1V/pa and 4mV/pa, 20dB setting: 127dB, 12dB setting: 120dB
  • Frequency response: 20Hz-20kHz +/- .25dB
