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. The Califone Infrared Classroom Audio Systems will help:

  • Improve academic achievement
  • Increase on-task behavior
  • Increase attention to verbal instruction
  • Improve comprehension for English
  • Language Learners
  • Improve ease of listening and teaching
  • Reduce vocal strain and fatigue on teachers
  • Works with PC/MAC teleconferencing systems such as Microsoft® Netmeeting so the entire class can participate in distance learning applications.

The benefits of the Infrared Classroom Audio System are enhanced by its use of “array” speakers. Array speakers are
most commonly seen at concerts and they deliver several advantages of being used in the classroom:

  • Array speakers target a tighter sound pattern directly at the audience with a narrower projection pattern. (A wider pattern bounces the sound off the walls and windows, which adds additional disruptive background noise to the very environment the system was installed to overcome.)
  • Array speakers distribute the sound more evenly so the volume levels are the same at the front & rear of the room.

Features:

  • Two ceiling-mounted IR receivers (more than what other brands offer as standard equipment) deliver twice the reception with less signal drop out and allows increased wireless coverage for classrooms of up to 2,000 sq. ft.
  • Beltpack transmitter & headset mic will operate all day long on a single charge. Ensures full wireless mobility to move about the classroom with its 40’ transmission range.
  • Quick operating guide printed onto the inside of the cabinet for easy referral.  Lockable metal case safely stores equipment while not in use.
  • Lockable metal case safely stores equipment while not in use
  • Two non-powered array speakers (PI30-SP) with protective steel grilles include wall-mounting brackets and hardware (not shown)
  • All array speakers feature three transducers with high-performance neodymium magnets, which are twice as efficient as conventional ferrite magnets, and deliver more power from a smaller, lighter speaker (which is also easier to install)
  •  Built in charging station for the wireless handheld mic. Includes a 2nd infrared frequency enabling both mics to function at the same time
  • Two powered array speakers (PI30-PS with PA-IRSYSB package only) comes with fixed and variable volume controls, for other daisy-chained speakers and one for a dedicated speaker system for students with special needs
  • Built-in mixing panel on the front with separate volume levels for both wireless mics, bass, treble controls, IR receiver, and an overnight recharger for the belt-pack transmitter
  • Balanced and unbalanced (3.5mm, XLR, 1/4”) mic inputs and aux-in connects the audio from a computer, LCD projectors, and other media players for enhanced audio amplification
  • Connects with low / high voltage paging systems (25V / 70V) with a dedicated sensitivity switch
  • Connects with PC/MAC teleconference systems such as Microsoft® Netmeeting, enables the entire class to participate in conference calls
  • Exterior flange for surface or flush-mounting the panel box
