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 ceilingmounted 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.

IR-820SP
Infrared Wireless Speaker
• Built-in infrared receiver and 20 W
digital amplifier
• Unique wide-dispersion acoustic
structure employing innovative
TOA technology to achieve
uniform output over a wide radius
• Bass-reflex speaker system
achieving a wide frequency range
and high power-handling capability
• Easy installation with quick, optimally positioned ceiling mounting
IR-802T
Infrared Wireless Tuner
• 3 AUX inputs for PC, TV/DVD player and MP3 audio player
• Output muting by 25 V line signal from telephone paging
• Equalizer control knobs for low-, mid- and high-frequency outputs
• Mixing output terminal for ALD (Assistive Listening Device)
• Frequency response optimized to reduce acoustic feedback in
100 m2 classrooms
IR-300M (for Teacher)
8 +
Infrared Wireless Microphone
• Easy-to-wear, neck-suspension design
permitting immediate use
• 2-level adjustable infrared light emission
intensity
• Lightweight body can be worn for long
periods of time without causing fatigue
(130g with 2alkaline batteries).
• Usable as transmitter for external microphone
• Antibacterial treatment
The wide-dispersion speaker provides ample 100 m2
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.
