The Royer dBooster In-Line Signal Booster s a phantom-powered ribbon and dynamic microphone signal booster and impedance buffer. It increases the level of passive low-output ribbon and dynamic microphones with a minimum of distortion or coloration.

Designed for professional applications, the dBooster provides two levels of clean gain boost; 12dB and 20dB, selectable by a front panel switch. The dBooster maintains headroom and gain regardless of load. The Class A input circuitry presents a high source impedance to the microphone, which minimizes loading (damping). This reduces coloration and distortion while at the same time improving headroom. By utilizing the 12/20dB gain switch, optimum balance between gain and headroom can be achieved for a variety of uses. The low-impedance output of the dBooster 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.

The dBooster gives excellent results with Royer R-121's, R-10's and stereo SF-12's. It also smokes on SM7B's and other dynamic mics! The dBooster is built in the USA and also available in a dual channel version, the dBooster2.

    Excellent preamp with a subtle and pleasing tonal character with more low end depth than the Mogaine unit. A must try! Front End Audio is also a top notch company! Buying a second unit.
