Royer R121 Matched Pair Ribbon Microphones The R-121 is Royer's flagship microphone and the worlds first radically redesigned ribbon microphone. The R-121 gives all of the warm, natural tonal response for which top engineers have always loved ribbon mics, but in a compact, lightweight, higher output, tough-as-nails package that was unheard of in a ribbon mic before the Royer R-121. Like many of the best loved classic ribbon mics, the R-121 has a figure-8 pattern, sensitivity in the dynamic mic range, and a warm, realistic tone and flat frequency response. But that's where the similarities end. By using advanced materials and a blend of cutting edge and old-school hand-build construction techniques, the R-121 is a far more versatile and user-friendly ribbon mic that can stand up to the most demanding tasks, including live stage use. It's built solid enough for us to give it a lifetime warranty. The R-121 redefined ribbon microphones so thoroughly that Recording Magazine wrote "...the Royer R-121 is destined to become one of the classic microphones of the 21st century”.
