Royer Labs recently released the new dBooster2 "phantom powered, two-channel in-line level booster/buffer for passive ribbon and dynamic microphones, and each channel doubles as a high-impedance DI input for guitars and other Hi-Z sources."

In a press release announcement, Royer Labs stated:

"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.
"

The new features added to the dBooster2 will take the already great design of the original dBooster, and bring significantly more utility to the device. This will make the dBooster2 a very handy tool to have in the studio, and on the road.
