INSTRUCTION MANUAL

INTRODUCTION

Thank you for selecng the Azden INFRARED system as your wireless classroom audio

soluon. We are condent that it will perform beyond your expectaons. For over 50

years, Azden Corporaon has been creang highest quality, reliable products adapng

the most advanced technology available. By taking advantage of the latest CAD design

and SMT producon techniques, Azden engineers are able to produce products that ex-

ceed the published specicaons and perform awlessly for years to come.

Azden INFRARED represents a breakthrough in wireless. Instead of the normal radio

waves that other wireless systems use, Azden INFRARED uses invisible light beams in

the infrared range. INFRARED’s enhanced performance assures you of the nest in au-

dio clarity and reliability. The specially selected high-frequencies provide you with trou-

ble-free performance, even in the uorescently lit classroom environment.

Infrared (IR) wireless microphone systems are the best soluon for classrooms. In to-

day’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, IR is perfect for classroom audio since, unlike other systems, it is short

-range and cannot penetrate walls. This means that your school can have as many class-

rooms as desired with individual audio systems without fear of interference. Since the

Azden system is dual-channel, a teacher can have one microphone and a second person

can also have a microphone. In addion, since each classroom system is on the same

pair of channels, teachers can move from room to room without having to switch micro-

phones.

In the real world, the ability to use mulple systems in the same locaon without fre-

quency interference will prove to be a tremendous benet to you. Using IR means that

the audio generated in your classroom stays within the classroom. Your discussions

cannot be overheard on other systems in other classrooms.

years of worry-free, high-quality performance.

○

EMIC TONE Control

Adjusts the system’s high frequency tone.

○

FCHANNEL 1/2 Indicator

Corresponding LED glows green when CHANNEL 1 or 2 is acvated.

○

GSENSOR INPUTS

Aach the IR sensor(s) IRD-66 and/or IRD-36 here using the RG-59 cable(s) (not

included). IMPORTANT: Plug the unused inputs using the supplied shorng

plugs. Failing to do so will severely reduce the working range of the sensor(s).

○

HSPEAKER Connectors

The ceiling or wall-mounted speakers will be connected here. Carefully follow

the + and—markings (speaker cables are not included).

○

ILINE OUT Outputs

Outputs the sound to other devices. Accepts the RCA plugs.

○

JLINE 1/2 Inputs

Any external audio source with a standard “Line-Level” output, such as a CD or MP3

player, DVD player, etc. may be aached here.

○

KPower Supply Jack

This is the power input. Plug the small, round connector of the supplied AD-DC adap

tor (BC-30) into the Power Supply Jack.

○

BRemote Volume Control

Controls the volume level. Press the “+” buon to increase the volume and “-” to

decrease.

○

K○

○

CStatus Indicator

The indicator LED shows GREEN, RED or ORANGE depending on the status or mode of

the IRN-20.

GREEN = on

Alternang RED/GREEN = recharge soon

RED = charging

Orange = charged

○

DDual Direconal Microphones

The IRN-20 uses two separate microphones (le and right) to provide a constant

transmied voice level as the user’s head is turned from side to side.

○

EBaery Compartment Lid

To open the baery compartment lid, hold the IRN-20 upside down, the lid facing

you, and the press the center of the lid with both thumbs and slide the lid upward.

Insert an AA rechargeable Ni-MH baery (included in the Azden Classroom Systems

IR-CSV and IR-WSV) or an AA Alkaline baery following the polarity marked inside the

baery compartment.

○

FMicrophone Gain Sengs

The IRN-20 microphone gain control is factory set and will not need adjusng. Turn-

ing the control by a jeweler’s Phillips-head screw driver (not included) will increase/

decrease the AF level.

○

GNeck Strap

To separate the clasp, grab the both end of the clasp and rmly pull them apart. To

reaach, simply snap the ends back in or slide one end to the other unl clicks. The

strap length can easily be adjusted by moving the sliders.

○

H Microphone Jack

Plug in an external microphone with 3.5mm mini plug here to override the IRN-20’s

microphones.

○

IBaery Charge Jack

Plug the BC-31 Baery Charger (included in the Azden Classroom System IR-CSV &
