Description Customer Reviews Manuals/Downloads

Protect young ears with the Califone Sound Alert Jack Box. An LED light on the unit lights up to signal students and teachers when the jack box volume is louder than the American Speech-Language-Hearing Association's recommended 85-decibel level. The durable ABS plastic Sound Alert jack box is ideal for listening centers, ELL and ELD and other language learning activities. It can also be used as a traditional jack box without charging the battery, but the warning LED feature will not operate. The Sound Alert jack box conserves its power by shutting off when no audio signal is present for 60 seconds and will power on automatically when there is an audio signal present. This Califone Sound Alert Jack Box comes backed by a one-year warranty.
