Califone Infrared Classroom Audio System. 

It Does More and Costs Less!

Califone addresses the most common obstacles to quality classroom and lecture hall sound-high cost, poor installation, 

inadequate acoustics, and high levels of ambient noise — with our Infrared Classroom Audio System. 

By utilizing “array” speaker technology, our innovative system increases the key signal-to-noise ratio to produce a more evenly 

distributed sound with twice the coverage and receptivity of other systems. In addition, the volume level is the same at the 

front and rear of the classroom, increasing students’ attention to verbal instruction. The speakers target the sound pattern 

directly at the audience — not randomly bouncing it off of walls — which improves teaching and listening, and 

comprehension for all students.
