Featuring a flush, tabletop-mount design, the AT8657/LED microphone socket allows for the easy use of any 21 mm gooseneck or button-style boundary microphone with a 3-pin XLRM-type output - including our ES945 and ES947 - in a variety of presentation environments.The sockets logic out capability permits control of remote devices from a programmable capacitance switch, so users can easily trigger an external device (e.g., a camera or light) with the touch of a button - an extremely useful feature in conference and boardroom installations. The socket also features a lock switch that automatically locks the microphone in place upon insertion, holding it securely until switch is manually released by user.Additionally, an integral Red/Green LED ring is controllable from a logic-enabled device and is powered by the microphones phantom power, eliminating the need for an additional power source.Each socket comes with a pair of rubber isolation rings and a metal retainer ring (for use with gooseneck mics only) to dampen surface vibrations.
