The Shure A400SMXLR shock mount set. It combines the A400SM shockmount with the A400 XLR insert, designed for use with gooseneck microphones like the Shure MX412, MX412S, MX412SE, MX418, MX418S, and MX418SE microphones. The shockmount's Shock-Stopper construction sonically de-couples your microphone from the mounting surface, reducing surface noise by an impressive 20dB. And because the XLR connection is already installed, all you need to do is mount the Shure A400SMXLR to your podium or tabletop and connect your microphone.
