The Kelly SHU™ FLATZ™ Shock-Mount System

The Kelly SHU FLATZ Shock-Mount System for the Shure Beta 91A is a professional isolation mounting solution designed specifically to optimise the performance of low-profile boundary microphones inside kick drums. Engineered to reduce unwanted vibration transfer and mechanical noise, the FLATZ™ system helps the Beta 91A capture greater attack, clarity and low-end definition while maintaining a cleaner, more controlled signal.

Ideal for live sound, studio recording and touring applications, the FLATZ™ Shock-Mount System securely positions the Beta 91A within the kick drum shell without bulky mounting hardware or improvised padding solutions. Its low-profile design preserves the microphone’s natural boundary response while improving isolation from drum shell resonance and stage vibration.

Designed for engineers and drummers seeking consistent kick drum performance, the Kelly SHU™ FLATZ™ system enhances microphone stability, improves tonal accuracy and helps achieve a tighter, more focused kick drum sound in both live and recording environments.
