Royer Labs R10 Matched Pair

Royer Labs R-10 Matched Pair consists of two factory-matched passive ribbon microphones — the accessible entry point to Royer's R-series, retaining the core technologies of the flagship models: the same 2.5-micron aluminum ribbon element as the R-121, the patented offset ribbon design, and construction suitable for both studio and live stage use. Three features distinguish the R-10 from other models in the line: a built-in three-layer windscreen, an internal transducer shockmount on silicon rubber grommets, and humbucking wiring around the transducer that cancels electromagnetically induced noise — making it the most physically rugged ribbon in the Royer catalog. The custom transformer designed by David Royer specifically for this microphone is deliberately 5 dB less sensitive than the R-121, which translates directly into 160 dB @ 1 kHz of headroom.

Three ribbon protection technologies — construction without compromise

The three-layer built-in windscreen limits air blasts and plosives and reduces proximity effect when close-miking guitars and acoustic instruments — vocal recording without a separate pop screen is feasible. The internal silicon rubber grommet shockmount isolates the ribbon element from vibrations transmitted through the stand and floor, which is particularly relevant in live stage environments. Humbucking wiring around the transducer cancels electromagnetically induced noise — valuable when miking guitar amplifiers with large mains transformers radiating strong magnetic fields. The cylindrical body with open grille design minimizes standing waves and comb-filtering effects associated with diffraction. The 2.5-micron ribbon is formed using Royer's patented direct-corrugation process, making it more resistant to stretching and sagging than traditional long-ribbon designs. The patented offset ribbon placement (Patent #6,434,252) gives the rear side a slightly brighter response at approximately three feet and closer (phase reversed).

Matched pair — stereo at an accessible price point

Factory matching eliminates the need to calibrate levels between channels in ORTF, X-Y, or drum overhead configurations. Output impedance of 100 ohms is lower than the R-121's 300 ohms — a result of the new transformer design — which allows the R-10 to drive longer cable runs. Sensitivity of -54 dBv requires a preamp with adequate gain; the R-10 pairs well with inline signal boosters. Applications: electric guitar, brass, drum overheads and rooms, strings, acoustic guitar, vocals, ambient capture. Five-year warranty; first ribbon replacement free within the first year of ownership.
