Royer Labs RSM-SS1 is a patented Sling-Shock suspension shockmount (Patent #8,571,250) — the smallest model in the line, designed for microphones approximately 25 mm (1 inch) in diameter, with a tolerance of +/- 1/8 inch. Dedicated for Royer's 1-inch diameter ribbon microphones: R-121, R-122 MKII, R-122V, and SF-12, as well as other cylindrical microphones of similar diameter. The RSM-SS1 is the first and most widely used model in the Sling-Shock series — the natural partner for the R-121 and R-122 in both studio and live stage environments. Like all Sling-Shock models, it completely eliminates rubber and elastic suspension elements, replacing them with a system of non-resonant nylon cord and damped steel springs. Hand-built from aircraft-grade aluminum at Royer's Burbank, California facility.
Nylon and springs instead of rubber — isolation without material degradation
Conventional shockmounts rely on elastic bands or rubber supports that degrade over time, lose tension, and require periodic replacement — with loose mic retention creating fall risk in the process. The RSM-SS1 addresses this at the design level: the nylon-and-damped-steel-spring suspension does not age, requires no maintenance, and needs no replacement parts. Isolation covers vibrations transmitted through the stand (appearing as rumble and broadband low-frequency disturbances), physical shocks, and mount self-resonance — the last problem being particularly relevant when close-miking electric guitar amplifiers at high power, where mechanical resonance of the mount introduces harmonic intermodulation artifacts at various frequencies into the recording. A built-in cable clip with a strain-relief loop reduces additional vibrations conducted through the microphone cable into the mic body. The adjustable grip with a knurled lock-down knob allows precise positioning and secure retention; the chamber interior is lined with felt or soft cotton to protect the microphone's finish.
Compatibility and position in the line
The RSM-SS1 accommodates cylindrical microphones approximately 25 mm (1 inch) in diameter, +/- 1/8 inch. Dedicated Royer models: R-121, R-122 MKII, R-122V, SF-12. It also fits other cylindrical microphones of similar diameter — including pencil condensers and dynamic microphones in standard 1-inch housings. The shockmount is compatible with standard microphone stands (European stand adapter included). The RSM-SS1 is the smallest of the three Sling-Shock models (RSM-SS1: 1"; RSM-SS24: 1.5"; RSM-SS251: 2"). Unconditional lifetime warranty.
