Advantages of Infrared
Infrared 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, cannot penetrate walls, and is dependent on line-of-sight. This means that a school can have as many classrooms as desired with individual audio systems without fear of interference. Since the Azden system is dual-channel, the 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.
