Shure A400MB Mute Button Accessory, White

Optimize conference rooms, control centers and security monitoring stations with the Shure A400MB mute button accessory. Designed for pro microphones, this compact white mute control provides intuitive local or remote mute capability—reducing accidental audio pickup and improving privacy and signal control during live meetings, surveillance operations, or broadcast monitoring. The A400MB supports configurable toggle, push-to-talk and push-to-mute modes and includes onboard programming for LED and touch-surface sensitivity, so installers can tailor behavior to your AV or security workflow. Installation is fast and clean: the adapter converts the 5-pin XLR output to a standard block connector for no-solder termination and fits a 1-1/8" (30mm) table cutout for discreet surface mounting. Included color rings and a low-profile profile ensure the control matches MX395-LED and MX400SMP-series gooseneck microphones and preserves your room’s aesthetics. Ideal for corporate boardrooms, surveillance monitoring rooms, courtrooms and broadcast environments, the A400MB simplifies integration with third-party control systems while enhancing user control and reliability. Add the Shure A400MB to your AV or security setup to improve mute control and streamline installations.
