The Royer model R-DB22 dBooster2 features two channels of dBooster ribbon & dynamic microphone signal boosting and impedance buffering technology. Each channel also doubles as a high-impedance DI.
When used as a signal booster, both channels of the dBooster2 increase the level of passive
low-output ribbon and dynamic microphones with a minimum of distortion or coloration.
Designed for professional applications, each dBooster2 channel offers two levels of clean gain
boost: 12dB or 20dB, selectable by a front panel switch.
The dBooster2's Class A input presents a high source impedance to microphones, minimizing
loading (damping) and improving headroom. By utilizing the 12/20dB gain switch, optimum
balance between gain and headroom can be achieved for a variety of uses.
The dBooster2's low-impedance output 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.
When used as a DI for unbalanced guitar level sources, the dBooster2 provides either 0dB or 8dB of
gain, selectable from the front panel switch. The single ended high-impedance (230K-Ohm) DI input
maintains headroom and gain regardless of load, with minimal distortion or coloration.
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
DI for direct electric guitar, electric bass, and other instruments
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
