Now you can use an unlimited number of systems in
the same building and not worry about frequency interference! The
Azden "Red" Series of infrared wireless microphones is the solution
for classrooms, auditoriums, churches, conference/meeting rooms,
and health clubs, and where ever security is an issue.
The two-channel IRR-30 receiver allows the use of two mics at the
same time. Each channel has its own frequency and every IRR-30 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.
