Royer Labs’ 25th Anniversary Microphone

Launch of R-10 ‘Hot Rod’ celebrates a quarter century of excellence.


15 March 2023

To kick off its 25th anniversary celebration, Royer Labs announces the R-10 ‘Hot Rod’ 25th Anniversary microphone — a passive, mono ribbon microphone that is designed for use in studios and live on stage. The limited-edition R-10 ‘Hot Rod’ is fitted with a custom Anniversary Edition transformer; has 5dB hotter output than the standard R-10 with a punchier, more open sound characteristic; and comes with a 25th Anniversary trim package that sets it apart from the standard R-10.

Like the original R-10, the R-10 ‘Hot Rod’ handles extremely high SPLs of 160dB @1kHz. Similarly, it has an internally shock-mounted ribbon transducer and 3-layer wind screen system — both combining to give the ribbon element excellent protection and make it an easy choice for live work; features lowered proximity effect that makes it an excellent choice for close miking instruments and singers; and carries a 5-year warranty with the first re-ribbon free. 

The R-10 Hot Rod’s patented offset-ribbon design positions the ribbon element toward the front of the transducer, which allows for high SPL handling on the front, logo side, and the option of a brighter response when recording lower SPL sound sources like acoustic guitar, ukulele and vocals on the backside — three feet or closer, in the phase reversed position.

John Jennings, Royer Labs’ Vice President of Sales and Marketing, commented on the new 25th Anniversary microphone, “Royer Labs is thrilled to be in our 25th year, and kicking it off with the R-10 Hot Rod is just pure fun. The guys in our shop cooked this version of the R-10 up and we’re all into it, with its cool looking trim package and its different sonic personality. It expands on the R-10 in interesting ways, creating a different flavor of R-10 that we think recording engineers and FOH engineers will really like.”
