Shure A400MB Microflex Mute Button and Adapter

The versatile design features a programmable switch that can be set for latched or momentary (push-to-talk/mute) modes. When used with multiple microphones, the A400MB can be set to local or remote mute control, allowing a user to simply mute their own mic or mute every mic in the room at the touch of a button.

Installation is easy the A400MB adapts the 5-pin mini XLR connector to a standard block connector with no soldering necessary. The mute button fits in tables that are between 0.59 to 1.18 inches thick. Separately available accessories allow you to mount the button further from the microphone and to interface with conferencing apps including Teams and Zoom.
