The Shure A400MB mute button accessory adds local or remote mute control via a programmable button for use with the Microflex MX395-LED low profile boundary microphones and MX400SMP-compatible modular gooseneck microphones (MX405/MX410/MX415). With an unobtrusive design ideal for surface mounting into boardroom tables, the A400MB adapter converts the 5-pin XLR output to a standard block connector for easy, no solder termination and hassle-free installation.
