Azden IR-CS Infrared Classroom Wireless Microphone System
For the past decade, probably no company has had more of their wireless microphone systems installed in classrooms across the country than Azden. Working with the engi-neering departments of the leading classroom amplification names, Azden has been at the forefront of the drive to improve the quality and reliability of sound available in class-rooms. Azden has been selected by these companies because of our long experience in producing reliable RF and infrared products, not for the "stage" but for everyday ap-plications, especially classrooms and conference rooms. Now, in addition to our continued partnerships, Azden is proud to introduce its own lineup of products, engineered specifically for the classroom.
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 a variety of other devices and sources. Cell phones, radios, TV, PA systems, police and emergency service systems, etc., 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 in-terference. Since the Azden system is dual-channel, the teacher can have one micro-phone 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.
THE COMPLETE CLASSROOM SYSTEM
Although you can purchase components separately to customize your own system, Azden provides two complete systems (IR-CS and IR-WS) which include: an IR receiver with ample power for 4 ceiling or 4 wall-mounted speakers and a built-in sensor array (IRR-30P), a small, lightweight chest-worn microphone/transmitter (IRN-10), a pass-around handheld microphone/transmitter (IRH-15c), an external ceiling-mounted sensor (IRD-60), and 4 high-quality in-ceiling speakers (ACS 6.5) or 4 compact wall-mounted speakers (AWS-4.5). All you need to complete the installation is the wiring for the speakers and sensor.
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 play-ers, 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 out-put 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.
A lightweight, chest worn, microphone/transmitter, the IRN-10 comes with an adjustable lanyard. It is both a microphone and infrared transmitter which wirelessly "links" the teacher to the IRR-30P receiver. It has a specially designed internal microphone array which provides great sound pick-up. With two switchable channels, a teacher can go from classroom to classroom with the same microphone! With just two "AA" batteries (alkaline or rechargeable) the microphone can be used the entire school day without re-charging or changing batteries.
IRH-15c handheld microphone
The perfect handheld "pass-around" microphone for student participation, this dual channel microphone/transmitter, operates on the channel that the teacher is not using. It is powered by two "AA" batteries (alkaline or rechargea
