Royer Labs was formed in 1998 to bring David Royer's unique, modern ribbon microphone designs to the world. When the California based company first opened doors, ribbon mics had been largely forgotten, but the R-121 and SF-12 quickly captured the imagination of recording enthusiasts around the world. This new generation of ribbon microphones proved to be a perfect match to the rise in popularity of digital recording, as engineers rediscovered the warmth, analog feel and smooth sound of ribbons. Today Royer Labs provides a comprehensive range of ribbon microphones for recording, live, and other professional applications, which are popular in recording studios and on stages all around the globe.

Overview

Two Channel In-Line Signal Booster & DI

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.
