Thank you for selecting the Azden “RED” infrared system as your wireless solution. We are
confident that it will perform beyond your expectations. For over 40 years Azden Corpora-
tion 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 exceed the published specifications and perform well beyond the warranty
period.
Azden “RED” represents a breakthrough in wireless. Instead of the normal radio waves that
other wireless systems use, Azden “RED” uses invisible light beams in the infrared range.
Through the use of infrared you will no longer be plagued by outside interference. “RED’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 rooms. Like all infrared, Azden “RED” will not operate correctly outside in the sunlight.
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 room stays in your room. Your discussions cannot be overheard on
other systems in other rooms.
Designed by professionals - for professionals, Azden “RED” will provide you with years of
worry-free, high-quality performance.
