The heart of the Azden infrared system is the IRR-30P powered, dual-channel receiver. It allows you to use and control the volume of 2 wireless microphones simultaneously, either for "team-teaching, or to use the handheld microphone for student pass-around. The receiver also has 2 stereo auxiliary inputs so that other line-level devices (CD players, MP3 players, VCRs, etc.) can be attached and played through the system.
The teacher can also send the audio to a recorder or video camera, using the line-level output jack. For bigger rooms or odd-shaped rooms up to 3 additional external sensors can be attached. With all 4 of the ceiling speakers attached to the IRR-30P, sound is spread equally throughout the room, allowing all students to hear equally.
