Toa Electronics Infrared Wireless Classroom Assistive Listening System

Assembled specifically for classroom use, TOA’s IR-802PA Infrared Wireless Classroom System includes a ceiling-mounted wide-dispersion speaker (with integrated receiver and amplifier), an easily accessed desktop tuner and a pair of lightweight IR wireless microphones, one each for the teacher and students.

The system is tailored to classroom size, thus avoiding unnecessary equipment installation. The wide-dispersion speaker provides ample 30ft x 30ft coverage, transmitting teachers’ and students’ normal speaking voices to everyone in the room, from front to back, with equal clarity and TOA’s renowned superior sound quality. The resulting easy interactive communication stimulates students and improves their understanding of the course content.
