IRR-30PKG5 - General Description
The Azden IRR-30PKG5 is a dual channel standard infrared package with a
IRR-30P dual receiver, a IRH-15C hand held microphone, a IRN-10 pendant
transmitter and a IRD-60 external sensor.
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 variety of other devices and sources. Cell phones, radios,
TV, PA systems, police and emergency service systems 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
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 class-room
system is on the same pair of channels, teachers can go from room to room
with-out having to switch microphones.
