Introduction
Thank you for selecting the Azden IRR-40P system as your wireless classroom solution. We are
confident that it will perform beyond your expectations. For over 50 years Azden Corporation
has been creating technologically advanced products. By taking advantage of the latest in CAD
design and SMT production techniques, Azden’s engineers are able to produce products that

The Azden IRR-40P represents a breakthrough in infra-red wireless technology. Instead of the
normal radio waves that other wireless systems use, the Azden IRR-40P uses invisible light beams
in the infrared range. The IRR-40P's enhanced performance assures you of the finest in audio
clarity and reliability. The specially selected high-frequencies provide you with trouble free
performance, even in fluorescently lit classrooms.
Infrared (IR) wireless microphone systems are the best solution for classrooms. In today’s RF
saturated world a regular (VHF or UHF) microphone system risks interference from a variety of
other devices and sources. Cell phones, radios, TV, PA systems, police and emergency service
systems, etc., can all interfere with VHF and UHF ‒ but not with IR. Furthermore, infrared is
perfect for classroom audio since, unlike the other systems, IR is short-range and cannot
penetrate walls. This means that your school can have as many classrooms as desired with
individual audio systems, without fear of interference. Since the Azden system is dual-channel, a
teacher can have one microphone and a second person can also have a microphone. In
addition, since each classroom system is on the same pair of channels, teachers can go from
room to room without having to switch microphones.
In the real world, the ability to use multiple systems in the same location without frequency
interference will prove to be a tremendous benefit to you. Using infrared means that the audio
generated in your classroom stays in your classroom. Your discussions cannot be overheard on
other systems in other classrooms.
Designed by professionals ‒ for professionals, the Azden IRR-40P will provide you with years of
worry-free, high-quality performance.
