Audix LCB1 Logic Control Button for On/Off Function

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 32mm 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.

The LCB1 gives the user the ability to have logic button functionality that is physically separated from a microphone or table base. This affords the option of a table microphone, such as a gooseneck or boundary microphone, to be positioned farther from the conference table’s edge where the mic coverage can clear laptop screens or other obstructions. In conjunction, the LCB1 can be positioned conveniently near the edge of the conference table, allowing for easy reach and access to button functionality. On/off, push-to-talk, or push-to-mute selections can be programmed at the DSP. In jobs where ceiling microphones are deployed, the LCB1 can be installed to indicate when overhead mics are live or to mute a particular microphone or zone.
