The R-122 is the world's first active ribbon™ microphone. Designed to work with phantom power, it delivers all of the warm, natural tone of Royer's R-121, but with +14dB greater output and impedance matching circuitry that makes it compatible with almost any mic preamplifier. Royer's proprietary offset ribbon transducer (Patent # 6,434,252) is the first of its kind, positioning the ribbon element closer to the front side of the microphone. An integral piece of the magic of all Royer R-series microphones, this arrangement gives the ribbon more room to move within the prime magnetic field while maintaining full frequency response during high SPL recordings.
