Shure A27SM ShureLock® Rubber Isolated Suspension Shock Mount for PG27, PG42, SM27, KSM27 and Beta 27

Product Overview

The Shure A27SM shock mount is an elastic-suspension microphone mount that isolates side-address condenser microphones from structure-borne vibration and surface noise. It is the factory-matched ShureLock rubber isolated shock mount for the SM27, KSM27, Beta 27, PG27, and PGA27, making it a direct-fit accessory for studio condenser microphone deployments and broadcast recording positions. Integrators specifying these microphones for fixed installs rely on the A27SM to keep desk thumps, floor traffic, and rack vibration out of the signal path.

Product Description

The A27SM suspends the microphone in a ring of elastic bands so that mechanical energy traveling through the stand or mounting surface is mechanically decoupled before it reaches the capsule. This elastic suspension shock mount is engineered specifically for Shure's large-diaphragm side-address bodies, so the cradle holds the microphone securely without the slippage common to universal mounts. The ShureLock rubber isolated shock mount threads onto standard microphone stands and booms, supporting both vertical and inverted overhead placement. In a commercial AV context it suits voiceover booths, podcast and broadcast studios, and house-of-worship vocal positions where vibration isolation directly affects intelligibility. Because it is purpose-built rather than adjustable, the A27SM removes guesswork during installation and provides repeatable mounting across multiple identical rooms. Replacement elastic bands are available, which keeps the mount serviceable over a long deployment life.

Key Features

• Elastic Suspension Isolation — The elastic band cradle mechanically decouples the microphone from the stand to reduce transmission of floor, desk, and rack-borne vibration into the capsule.
• ShureLock Secure Mounting — The ShureLock design holds the microphone firmly in the cradle so it stays positioned during long recording sessions and overhead placement.
• Model-Matched Fit — Designed specifically for the SM27, KSM27, Beta 27, PG27, and PGA27, it provides a precise, repeatable fit without adapters.
• Standard Stand Compatibility — Threads onto common microphone stands and boom arms used throughout studio and commercial AV installations.
• Serviceable Design — Replacement elastic rings are available, extending the usable life of the mount in high-utilization environments.
