LightSPEED Personal FM Systems enhance instructor voice information presented to students, whether children or adults, with learning or sensory difficulties.

A teacher or coach wearing the 370T Transmitter with a lapel, optional lavaliere or optional headset microphone can communicate privately to a student wearing the 370R Receiver and headphones from anywhere in the classroom, gym, cafeteria, playground, or on the sports field. The instructor’s voice is amplified and delivered directly to the ears of the student.

Since the LightSPEED LES 370 is a wireless system, both the teacher and student can move freely and still communicate with crystal clarity at distances up to 300 feet.

Working within the 216-217 MHz assistive listening band, the LES 370 has two frequencies built in. Utilizing two quartz crystals, the LES 370 can operate on one of two frequencies by changing channels with a slide switch. (A frequency is a special segment of the “airwaves” designated by the Federal Communications Commission so that the Transmitter can “talk” to the Receiver.)

The LES 370 operating frequencies correspond with the frequencies that Phonak uses in their MicroLink™ systems. If properly matched, the LES 370 may be used with matching Phonak system frequencies.
