Royer R-DB20 dBooster
The
Royer R-DB20 dBooster
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; 12 dB and 20 dB, 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 12/20 dB 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
