Marketing Information |
Califone understands that the proper
utilization of audio technology can assist classroom learning and
student comprehension.
Acknowledged research validates the use of enhanced sound field
amplification in learning areas. The Infrared Classroom Audio System
delivers all of the benefits of sound field amplification with greater
audio coverage & reception with dual ceiling sensors to expand the
coverage area and avoids “drop out” of the signals. Two wireless mics
ensure the teacher and students will be heard by everyone in addition to
amplifying audio played from computers and other sources. It can also
connect with secondary systems (such as an assistive listening system)
as well as announcements made from the school's main office. |
