Royer Labs has announced its second generation in-line signal booster, the dBooster2, a phantom powered signal booster and impedance buffer for both ribbon and dynamic microphones that also offers independent 2-channel functionality and doubles as a DI to accommodate signal levels for electric guitar, bass, and other unbalanced guitar level sources.
With both channels having the ability to serve as an in-line signal booster, a DI, or one channel of each, the dBooster2 is well suited for applications such as miking low volume sound sources, recording direct to a DAW interface, interfacing with long cable runs to maintain audio quality, or as a DI.
When used as a signal booster, both channels of the dBooster2 increase the level of passive low-output ribbon and dynamic microphones with stated minimum distortion or coloration. The unit’s input stages are designed like the front end of a high-end microphone preamplifier, and you can hear it. Each channel offers two levels of gain boost: 12 dB or 20 dB in Mic Mode, selectable by a front panel switch.
dBooster2’s Class A input presents a high source impedance to microphones, minimizing loading (damping) and improving headroom. By utilizing the 12/20 dB gain switch, more optimized balance between gain and headroom can be achieved.
When used as a DI for unbalanced guitar level sources, the unit provides either 0 dB or 8 dB 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. The unit’s balanced, low-impedance outputs provide the ability to drive digital interfaces or standard mic preamps. In addition, it is designed to minimize signal loss over long cable runs.
dBooster2 helps protect ribbon mics from phantom power hits, providing increased headroom at the preamp and giving true electrical isolation while minimizing mic loading. Each channel operates independently and is electrically isolated from the other. Further, it is stated to drive difficult loads such as mic splitters and vintage-style preamps without loss of gain or increased distortion.
John Jennings, Royer VP of sales and marketing, states, “The dBooster2’s circuitry is pure Royer, taking the in-line lifter concept to a whole new level of performance that you can really hear, AND its two DI’s are excellent for the loads of musicians/recorders who use DI’s regularly. I’m a big fan of the creative choices the dBooster2 opens up. It’s a simple looking device that’s very easy to use, but the design is first class all the way through and we’re proud to offer it to the recording community.”
The new dBooster2 is available at an introductory street price of $299 (U.S.), and will ship in January 2022.
