Azden IRR-23 Infrared Wireless Receiver (Dual Channel)
[AZIRR23]

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-23 receiver allows the use of two mics at the same time. Each channel has its own frequency and every IRR-23 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-10j) 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.
