With unobtrusive design for surface mounting into boardroom tables, the Shure A400MB converts the 5-pin XLR output to a standard block connector. It 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).
