AZIRR15PKG1 - General Description
The Azden IRR-15PKG1 is a single channel standard infrared package with a
IRR-15 receiver, a IRH-15C hand held microphone and a IRD-60 external
sensor.
Infrared is perfect for classroom audio because it 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. And 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.
