A dual in-line signal booster capable of driving difficult loads, such as mic splitters and vintage style preamps, without increased distortion or loss of gain.

The dBooster2 from Royer is comprised of the two channels of the original dBooster, plus both channels double as high-quality, super clean DI's for electric guitars and bass. Both channels are fully independent so you can plug in two mics at once or use both channels for DI’s, or mix them up, as there is one side for a mic and the other for DI. With microphones plugged in, the dBooster2 lets you switch between 12dB and 20dB of gain. When using the dBooster2’s DI inputs, you can select 0dB (unity) gain, or switch to 8dB of gain if you need more level. In mic mode, the 20dB setting gives loads of clean boost for recording softer instruments and singers. For higher volume instruments or loud singers, switch to the 12dB setting to keep from overloading your preamp or digital interface. The dBooster2’s dual Class A input stages give crystal clean gain with virtually no noise or self-distortion. The dBooster2’s low-impedance output gives optimal performance in the studio and also shines on live stages, driving long cable lengths and difficult loads like mic splitters and vintage-style preamps with no distortion, no loss of gain and excellent headroom.
