The Azden IRR-30J is a two channel infra--red receiver that allows the use of two mics at the same time. Each channel has its own frequency and every IRR-30J uses the same two frequencies. The receiver''s built-in sensor array allows complete freedom of movement in a 1600-sq.ft. room. For larger rooms, up to three wall/ceiling mountable external sensors (IRD-30 or IRD-60) increase the working distance. If the receiver is mounted in a secured cabinet the third sensor input disables and replaces the receiver''s internal sensor.
Now you can use an unlimited number of systems in the same building and not worry about frequency interference! The Azden "Red" Series of infra-red wireless microphones is the solution for classrooms, auditoriums, churches, conference/meeting rooms, and health clubs, and where ever security is an issue.
