The CB-85 is a ceiling mounted, hands-free, talk back microphone that allows a teacher to answer an intercom call from anywhere in the classroom.  Mounted in the ceiling tile with a single-gang enclosure, the CB-85 has a subtle, low-profile appearance.  When an intercom call arrives, audio volume from classroom sources will be muted to ensure clear audio sound for the duration of the communication.  When the communication is complete, audio volumes will be restored to the classroom sources in use prior to the intercom call.
