The Audiophile Mic Lifter
The Royer dBooster is an extraordinary gain boosting device unlike any other inline lifter, with design and performance specs like the front end of a high-end preamplifier and a sonic signature that will enable even the most familiar low output passive mics of all flavors to shine like never before.
dBooster delivers better than double your passive mic’s output; or, with the flick of a button, quadruple the output!
 
* True Class-A input stage
* Extreme RF protection
* Crystal clear gain with virtually no noise or self-distortion
* Enormous amount of headroom – will not break up!
* Low impedance output handles splitter cables and long cable runs beautifully
