Digital Assistive Listening Systems
Digital FM Assistive Listening Systems are designed primarily for use in the classroom, where there is no sound amplification system in place.
They offer freedom of movement for the teacher and the student, and perhaps most importantly, they provide 2 way communication.
The Digi-Wave Team Teach system below allows for 2 teachers and one student, or 1 teacher and 2 students. Or you can build your own system from the transceivers and receivers shown below.
