IR-CSV Infrared System

Complete IR classroom system with remote transmitter volume control.

CLASSROOM PROVEN

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 engineering 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 applications, 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.

THE ADVANTAGES OF INFRARED

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 interference. 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

The IR-CSV is a complete system and includes the (IRR-40P) receiver that supplies ample power for 4 ceiling speakers, a small, lightweight chest-worn microphone/transmitter with volume adjust (IRN-20), a mini lightweight pass-around handheld microphone/transmitter (IRN-30), an external ceiling-mounted sensor (IRD-60), and 4 high-quality in-ceiling speakers (ACS 6.5). All you need to complete the installation is the wiring for the speakers and sensor.

COMPONENTS

IRR-40P Powered 2-channel IR Receiver
The New Azden infrared IRR-40P powered, dual-channel receiver allows you to use 2 wireless microphones simultaneously, and you can also adjust system volume right from the IRN-20 pendant style transmitter. 2 wireless microphones can be used for, “team-teaching, or with the mini handheld microphone (IRN-30) 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 external sensors can be attached. With all 4 of the ceiling speakers attached to the IRR-40P, sound is spread equally throughout the room, allowing all students to hear equally.

IRN-20 Neck-worn IR Transmitter with Volume Control
A lightweight, chest worn, microphone/transmitter, the IRN-20 comes with an adjustable lanyard. It is both a microphone and infrared transmitter that wirelessly “links” the teacher to the IRR-40P/IRR-30/IRR-30P receiver. When used with the IRR-40P you can adjust system volume right from the IRN-20 itself for ultimate flexibility. The IRN-20 also has a specially designed internal microphone array that provides great sound pick-up. With just one “AA” battery (Alkaline or rechargeable 1HR-3U only) the microphone can be used the entire school day without re-charging or changing batteries.

IRN-30 Mini Handheld IR Microphone/Transmitter
A lightweight, handheld microphone/transmitter, the sleek IRN-30 is both a microphone and infrared transmitter that wirelessly “links” the teacher to the IRR-40P/IRR-30/IRR-30P receiver. The IRN-30 microphone provides great sound pick-up. With just one “AA” battery (Alkaline or rechargeable 1HR-3U only) the microphone can be used the entire school day without re-charging or changing batteries.

IRD-60 Sensor
In most classroom situations, a single well-positioned IRD-60 external IR sensor provides complete classroom coverage. Mounting is easy, and the sensor is connected to the IRR-30P receiver with standard coaxial wire.

ACS-6.5 In-Ceiling Speaker
The ceiling speaker was designed to provide optimum performance for the teacher’s voice in addition to audio from other sources (CD/MP3 player, VCR, etc.). Each speaker features a sealed-back enclosure and 6 ½” polypropylene midrange/woofer to produce natural bass response, while the coaxial mounted 1″ polycarbonate tweeter provides superior high frequency response. Easily flush-mounted in any drop ceiling, four of these speakers provide smooth, evenly distributed sound throughout the classroom. Designed to handle up to 50 Watts (continuous program) each. All students can enjoy enhanced audio equally.

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.

COMPONENTS

IRR-30P receiver
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.

IRN-10 microphone
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 rechargeable) and is compatible with all Azden infrared models.

Both the IRN-10 and IRH-15c can recharge internal NiMH batteries (1HR-3U only) when a BC-29 wall-charger is used. There’s no need to remove the batteries to recharge.

IRD-60 sensor
In most classroom situations, a single well-positioned IRD-60 external IR sensor pro-vides complete classroom coverage. Mounting is easy, and the sensor is connected to the IRR-30P receiver with standard coaxial wire.

ACS-6.5 in-ceiling speaker
The ceiling speaker was designed to provide optimum performance for the teacher’s voice in addition to audio from other sources (CD/MP3 player, VCR, etc.). Each speaker features a sealed-back enclosure and 6 ½” polypropylene midrange/woofer to produce natural bass response, while the coaxially-mounted 1″ polycarbonate tweeter provides superior high frequency response. Easily flush-mounted in any drop-ceiling, four of these speakers provide smooth, evenly distributed sound throughout the classroom. Designed to handle up to 50 Watts (continuous program) each. All students can enjoy enhanced audio equally.
