The Avantone SSM Professional Shockmount greatly reduces microphone noise caused by vibration, handling, etc. The SSM features a weighty, all-metal construction that makes it durable and further aids against energy transference that may cause noise. Its 4 o-ring suspension bands are durable and made of a resilient ethylene propylene material that is highly resistant to breaks and tears. The o-rings may be attached horizontally, vertically, or crossed for added tension. The SSM will successfully mount Avantone microphones, or third-party microphones measuring 0.74 - 0.86" (19 - 22mm) in diameter.
