- Page 2 INTRODUCTION Thank you for selec ng the Azden INFRARED system as your wireless audio solu on for your classroom or conference room. We are confident that it will perform beyond your expecta ons. For over 60 years, Azden has been crea ng highest quality, reliable prod- ucts adap ng the most advanced technology available. By taking advantage of the lat- est CAD design and SMT produc on techniques, Azden engineers are able to produce products that exceed the published specifica ons and perform flawlessly 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 finest in au- dio clarity and reliability. The specially selected high-frequencies provide you with trou- ble-free performance, even in the fluorescently lit classroom/conference room environ- ment. Infrared (IR) wireless microphone systems are the best solu on for classrooms or con- ference rooms. In today’s RF saturated world, a regular (VHF or UHF) microphone sys- tem 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 classrooms 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 system is on the same pair of channels, teachers can move from room to room without having to switch microphones. 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 benefit to you. Using IR means that ...

Page 6: Remote Control
IRR‐50P RECEIVER A. Turning It On When the unit is plugged into power source, the LED indicator in the middle of the emi er dome will light in RED. This indicates that the unit is now in the standby mode. Note that LED Indicator the unit will not accept commands from the RED: Standby Remote for the first 7 seconds since it is GREEN: Power on GREEN BLINKING: Receiving command from Remote plugged in. Turn the power on by pressing the Power Switch on the Remote Control and the LED indicator on the dome will turn to GREEN and the unit is ready to receive signals from the Transmi ers. The LED indicator will turn to RED when you turn the power off by using the Remote. The unit is now in the Standby mode. B. Remote Control Power Switch Remove the ba ery compartment door by slid- ing it towards the arrow on the cover and insert 2 AAA alkaline ba eries following the polarity marked inside the compartment. Use the Power Switch to turn the unit on and off and the appropriate volume bu ons to change the volume of the respec ve channels. ... - Page 7 C. Pager Interrupt Feature When the Pager Interrupt feature is ac vated, the pager signals will override all other sig- nals. In order to ac vate the Pager Interrupt feature, connect the pager wires to the Pager Con- nectors and turn the Select Switch to 100V/70V (for high impedance output) or 20V (for low impedance output). Use the Pager Volume Control Knob to adjust the pager volume. When the pager signal is received while the unit is on, all 3 channels Pager Connectors will be immediately muted and only the pager signals will be output. A er the pager signals stopped, the Pager Volume Control 3 channels will automa cally be re- instated in a few seconds. When the pager signals are received when the unit is in standby, the unit External Sensor Connector will automa cally be turned on and the pager signals will be output. Select Switch D. PREOUT & RECOUT PREOUT is an output RCA jack for an external amplifier, etc. The output volume level will not be controlled by the Remote. RECOUT is an output RCA jack for an external recorder, etc. The output volume level will ...
- Page 8 The opera ng range of the Remote Control is approximately 30 (10 m) from the Receiv- er (IRR-50P). The range is subject to the environment. When using the Remote while a Transmi er(s) is in use, make sure to operate the Trans- mi er well within the opera ng range. If the signals from the Transmi er to the Receiver is weak, using the Remote may cause some interrup ons. The IRR-50P’s built-in amplifier is designed to accept up to 4 speakers with 4Ω imped- ance. Do not use speakers with smaller impedance since doing so may cause troubles in the amplifier. IRN‐20 MICROPHONE/TRANSMITTER ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ ○ 8 ...
