The LCB1 is a discrete button designed to remotely control the on-off functions of a microphone (or other devices) when used in conjunction with a logic-enabled media system for video and teleconferencing. Unobtrusively rising less than 3mm above the surface of a table and only 29mm in diameter, the LCB1 features a precision machined housing, a contact closure, and a 3-5 V DC logic controlled LED indicator. The LCB1 logic button is simple to install and does not require external power supplies, relays, or extra resistors. Mechanically separate from the microphone, The LCB1 gives tactile button response while keeping any potential noise out of the audio path.
