The Shure A89M-CC is a professional shock mount system featuring Rycote's patented Lyre suspension technology, designed to isolate handheld microphones like the Shure SM58 from mechanical vibrations and handling noise. This accessory replaces the standard microphone clip, offering a significant upgrade in performance for vocalists and presenters in live sound, broadcast, and recording applications. The core of the system is a set of Rycote Lyre elements—flexible, curved arms made from a specialized polymer—that cradle the microphone body. These Lyres act as a highly effective passive filter, absorbing low-frequency vibrations transmitted through the mic stand from floor movement, cable pulls, or accidental bumps before they can reach the microphone's capsule. This results in a cleaner audio signal with reduced rumble and thumps, allowing the true character of the voice to be captured without low-frequency contamination.

The mount includes the CCA (Connector Cover Assembly), which is a specific adapter that allows the shock mount to be securely attached to standard microphone stands with a 5/8"-27 threaded connector. The assembly is designed for quick and tool-free installation; the microphone slides easily into the Lyre cradle, and the entire unit then screws directly onto the stand. The Lyre suspension provides isolation in multiple axes, effectively damping vibrations from all directions. This is particularly beneficial in live environments where stages can be prone to vibration from foot traffic, subwoofers, or moving set pieces, and in broadcast studios where even subtle noises can be problematic.

Built for durability and repeated use, the A89M-CC is constructed from robust materials that maintain their elastic properties over time. It provides a secure yet gentle hold on the microphone, protecting the finish from scratches. For sound engineers and performers seeking the highest quality vocal capture, this shock mount is an essential accessory that solves a common but often overlooked problem. By mechanically decoupling the microphone from its stand, it ensures that the microphone only picks up the intended sound source—the performer's voice—delivering a noticeably cleaner and more professional audio output.
