TOA innovative all-in-one solution

 Uniform classroom-wide sound quality with single
wide-dispersion speaker

 Minimized system components
(tuner, 2 microphones and integrated speaker)

 Quick, easy installation requiring just one CAT-5
cable.

 TOA lightweight, low-fatigue
infrared wireless microphones

Assembled specifically for classroom use, TOA’s new 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.

A

This system requires only a wide-dispersion ceiling speaker, with
built in amplifier and receiver, plus an IR wireless tuner all
connected by one CA T-5 cable, reducing installation time and
cost.
