Audio system broadcasts announcements, too

Califone International, Inc., has upgraded its Infrared Classroom Audio System to allow announcements from the school's central office to be played directly through the audio system in each classroom.

The redesigned console now features a dedicated port that receives an audio signal directly from the school's office, supporting both high and low voltage systems. In addition, the console includes a local volume control, allowing teachers to determine how loud office announcements should be in their individual classrooms.
