Manufacturer's Description from Royer

The dBooster is the industry’s cleanest in-line phantom powered signal booster for non-powered ribbon and dynamic microphones. It provides two steps of gain; 12 dB or 20 dB switchable, bringing new life to low output mics for use on vocals, acoustic guitar, ukulele, etc.

The dBooster generates virtually zero distortion and self-noise even in the highest gain setting. Its gain levels remain consistent, regardless of the preamps used or the electrical load.

*We’ve measured all of the in-line- preamplifier products made today and found high levels of distortion in all of them, and they often lose output level when loaded. No such issues with the Royer dBooster! The dBooster gives amazing results with SM-7s on vocals. Set for 20 dB of gain for softer singers or dial back to 12 dB to keep your preamp or DAW from breaking up when a louder singer wants to eat the mic.


The dBooster pairs beautifully with our R-10 ribbon microphone on vocals and acoustic instruments.

*The R-10 has 5 dB less output than an R-121, so the dBooster’s extra level is very helpful on softer recordings.

The dBooster is hand-built in the USA and ships from our Burbank headquarters.



 ♦ Switchable 12dB/20dB gain

 ♦ Class A input stage

 ♦ Safe for use on all ribbon mics

 ♦ Wide frequency bandwidth

 ♦ Retains sound quality on long cable runs

About Manufacturer

After years of designing and manufacturing microphones in Los Angeles, David Royer teamed up with Rick Perrotta, former President and co-founder of the prestigious Matchless Guitar Amplifier Company, and together with studio owner Rafael Villafane and musician/marketing director John Jennings, formed Royer Labs, a California based company dedicated to the development and production of high quality ribbon microphones and transducer elements. DAVID ROYER Best known for his ribbon mics, David has designed countless other mics and outboard devices that are in use throughout numerous LA studios. When David's not designing new gear, his idea of fun is climbing desert mountains or pounding dirt roads in his new pickup. RICK PERROTTA Rick Perrotta's name may sound familiar - he and Rafael Villafane owned LA's Baby-O Recorders during the 80's, then Rick went on to co-found Matchless Guitar Amplifiers, where he was President and Production Chief of the prestigious amp line until 1995. At the helm of Royer Labs, Rick brings an extraordinary level of craftsmanship to every Royer microphone (hold one in your hand and you may never give it back!). JOHN JENNINGS John worked for years as a guitar player and singer, in the studio and on the road. He took an 8-year detour into the corporate world as VP Sales & Marketing for an LA communications firm, but came to his senses in 1996 and ditched the suit to get into pro-audio manufacturing and sales. John handles sales and marketing for Royer Labs. RAFAEL VILLAFANE Rafael Villafane co-founded Baby'O Recorders with Rick. He has produced a #1 and numerous top ten hits in the US and abroad. He drinks too much. Owns a club in Acapulco (Baby'O). If you can prove you own a Royer product, the first ten tequilas are on him---really. Drives too fast. Been doing a record for ten years he STILL can't finish. Has a six-second attention span. He torched a school with young pal Jeff "Skunk" Baxter in Mexico City when they were kids. What else? Oh yeah, he's Mexican... nobody's perfect. CHRIS PERROTTA As another co-founder of Matchless Amplifier Company, Chris was responsible for the high quality detail work that Matchless is famous for, including the light up "dashboard" and three dimensional logo. At Royer, Chris is the chief mechanical designer and another confirmed precision freak. Every Royer microphone owes its beauty and elegance to Chris wonderful interpretations of the designers art.
