Shure A300SM ShureLock® Wire Rope Shock Mount. Works with KSM353/ED

Product Overview

The Shure A300SM is a ShureLock wire rope shock mount that provides secure thread-lock mounting with maximum vibration isolation for the KSM353/ED ribbon microphone. Built around a wire-rope suspension rather than elastic bands, it is engineered for permanent and high-value studio installations where the KSM353/ED must be decoupled from structure-borne noise. For broadcast and recording integrators specifying Shure's flagship ribbon microphone, the A300SM is the manufacturer-matched isolation mount.

Product Description

The A300SM suspends the KSM353/ED in a steel wire-rope cradle that mechanically decouples the microphone from the stand, isolating it from floor traffic, HVAC vibration, and rack-borne mechanical noise that would otherwise transfer into the ribbon element. Wire-rope isolation does not degrade or lose tension over time the way elastic suspensions can, which makes it well suited to permanent broadcast and studio installations where long-term reliability matters. The mount uses a ShureLock thread-lock engagement to hold the microphone firmly and prevent rotation under cable load. Because the KSM353/ED is a premium dual-voice ribbon microphone used in critical recording and broadcast positions, the maximum isolation the A300SM provides directly protects low-frequency intelligibility and removes rumble from the captured signal. The A300SM is a model-specific accessory, delivering repeatable placement and performance across multiple identical studio positions. It is the recommended isolation solution when the KSM353/ED is mounted in any environment subject to structural vibration.

Frequently Asked Questions

Which microphone does the A300SM fit?
The A300SM is designed specifically for the Shure KSM353/ED ribbon microphone.

How does it differ from the A300M stand mount?
The A300M provides secure thread-lock stand mounting, while the A300SM adds a wire-rope suspension for maximum vibration isolation. Choose the A300SM when the microphone is in an environment subject to floor, HVAC, or rack-borne vibration.

Why a wire-rope suspension instead of elastic bands?
Wire-rope suspension maintains consistent isolation performance over time and does not lose tension or degrade like elastic bands, which suits permanent broadcast and studio installations.

Does it mount to a standard microphone stand?
Yes. It uses a ShureLock thread-lock engagement compatible with standard microphone stand and boom threads.

Is it covered by a warranty?
Shure accessories are covered under Shure's standard manufacturer warranty. Contact Creation Networks for current warranty and support details on this item.
