IRW-LT6X BODYPACK TRANSMITTER
b. Adjust the IRW-LT6X Volume Control(6) to minimum and slide the Power
Switch (2) to the ON position. The bi-color Power ON/LOW Battery LED
Indicator (1) will light green, indicating that the transmitter is on. In the case of low
battery strength, the indicator will light red, indicating that the batteries should be
replaced with fresh ones or the NiMH batteries should be recharged. The optional
IRRA-1 Recharging Adapter can be plugged directly into the IRW-LT6X DC Input
Jack(3) from an AC power outlet for easy charging of NiMH batteries. When the
recharging adapter is plugged in, the LED Indicator will light red. The LED indicator
will light green when the batteries are fully charged.
INTRODUCTION
Thank you for purchasing the NADY IRW-220X infrared wireless microphone system and
congratulations on your choice. The IRW-220X is loaded with top professional operating
features and is the best performance and price value available in infrared wireless systems.
USING THIS MANUAL
This booklet gives instructions for the operation of the IRW-220X wireless system, including
handheld and lavalier systems. Please read the instructions for your system completely
before operating unit.
c. The IRW-220X receiver IR LED Indicator of the corresponding channel should now
be lit green. While speaking into the microphone, slowly increase the IRW-LT6X
Volume Control(6) and adjust the volume control on the receiver, and also on the
Mixer/P.A. to the desired level while taking care to avoid acoustic feedback. The
microphone is now ready to use. For optimum performance and range, make sure
that the IR Emitter (4) is not covered by the body or clothing and has an
unobstructed line of sight with the IR Sensor.
[Note: Observe care in selecting volume, transmitter location, and speaker placement
so that acoustic feedback (howling and screeching) will be avoided. Please also
observe the pickup patterns of the microphone selected: omnidirectional mics pick up
sound equally from all directions and are prone to feedback if not used carefully.
Unidirectional mics are more resistant to feedback, but pick up sound sources best
that are directly in front of the microphone. Also, mics that are farther from the sound
source, such as lapel mics, require more acoustic gain and thus are also more prone
to feedback than close-source mics such as handheld mics that are used close to the
mouth.]

1. Transmitter Set-up
Slide down the Battery Compartment Cover (8), as shown, exposing the battery
compartment. Insert 2 fresh AA alkaline batteries, NiMH rechargeable batteries, or the
optional IR-BBP battery pack while observing the correct polarity as marked. Set the
Channel Selector Switch (9) to the desired channel of operation and slide the cover back
into position on the unit.
(Note: Make sure the transmitter is off when changing the
batteries.)
2. Operation
a. The IRW-LT6 is provided with a 3.5mm Locking Jack (5) for connecting the
microphone. Plug in either the LM-14/O Lavalier/Lapel Mic (10) as supplied.
To secure the connection, turn the metal slip ring on the plug clockwise to thread it on
the jack. To unplug, reverse the process. Clip the transmitter to your clothes/belt, or
hang the transmitter on your chest using the supplied neck worn lanyard. Make sure
the IRW-LT6X Emitter (4) has a clear line of sight with the IR Sensor. To use the
lavalier mic, attach it at upper chest level. Do not place the mic too close to the mouth
— a distance of about 6" usually works best.

1. Transmitter Set-up
Unscrew and remove the Battery Compartment Cover (1) by sliding it down off the
microphone to expose the battery holders. Insert 2 fresh AA alkaline batteries, NiMH
rechargeable batteries, or the optional IR-HBP battery pack while observing the correct
polarity as marked, and screw the cover back on the battery compartment.
(Note: Make
sure the transmitter is off when changing the batteries.)
2. Operation
Slide the Power Switch (2) to the ON position. The Power LED Indicator (1) will
light green, indicating that the transmitter is on. In the case of low batteries, the indicator
will be off, indicating that the batteries should be replaced with fresh ones or the batteries
should be recharged. The optional IRDR-2 Dual Microphone Recharger can be used to
recharge two IRW-HT6X simultaneously by placing the handheld microphones directly into
the mic holders without removing the rechargeable batteries. When the microphone is
placed in the recharging adapter, the LED Indicator will light brightly red. The LED
indicator will light green when the batteries are fully charged.
The microphone is now ready to use. The IRW-220X receiver IR LED Indicator of the
corresponding channel should now be lit green. While speaking into the microphone,
adjust the corresponding Volume Control on the receiver and also on your Mixer/P.A. to
the desired level. For optimum performance and range, make sure that the IR emitter at the
base of the transmitter is not covered by the hand and has an unobstructed line of sight
with the IR sensor.
[Note: Observe care in selecting volume, transmitter location and speaker placement so
that acoustic feedback (howling and screeching) will be avoided.]

(6) Mixed Output RCA Jack
1. Powering the Receiver
Plug the Power cord (3) into an AC outlet (110-120 VAC). Turn on the IRW-220X using
the Power Switch (1). The Ch A and Ch B IR Reception LED Indicators (2) will
light green when the corresponding transmitter is on and red when the transmitter is off.
Turn off the IRW-220X when not in use.
2. Connecting the Audio Output
The IRW-220X receiver provides a low line level Mixed Output to the unbalanced RCA
Jack (6). This can be connected to a mixer or a P.A. System using the supplied RCA to
1/4" audio cable or any RCA phono plug cable (not included). The audio of both
Channels A and B are mixed together at this output. The Channel A and B mix is dependent on the separate Channel A and Channel B Volume Control (5) settings located on
the back panel of the receiver. Always make sure the mixer/P.A. volume is turned to
minimum before plugging the audio cable into the receiver or before turning the receiver
on/off (if the audio cable is already connected) to avoid possible sound system damage.
3. Connecting the IRW-1S IR Sensors
Connect the IRW-1S IR Sensors to the IRW-220X receiver by plugging both sensor coaxial
cable plugs into the Infrared Sensor Inputs (4). Each Sensor input will receive both
channels A and B signals.

IRW-1S INFRARED (IR) SENSORS
(3)
1. Operation
The IR Sensors act as “antenna” for your infrared wireless microphone system. A multiple
array of wide angle IR-sensitive LED’s, behind the front panel receptors, receives the
infrared signal emitted by your IR transmitter. The Sensor Power LED (2) will light to
indicate the sensor is properly connected to the IRW-220X Receiver. The Channel A and B
IR LED indicators, located on the front panel of the receiver, will light green when an
infrared signal on the corresponding channel is detected.
2. Installation
The IRW-1S sensors can be mounted on walls using any of the Wall Mounts (3)
included. To ensure proper optimum operation, observe the following installation rules:
a. Position the IR Sensors with their front panel receptors facing the entire area of
transmitter operation. If this is a wide area, angle the receptors to cover the maximum
area range. The diagram on the opposite page shows a suggested positioning for the
IR Sensors.
Note: The IR sensors will need to be positioned differently for each environment.
During installation, power up the IRW-220X and have one person walk around the
desired location, with the transmitters on, while another person positions the IR Sensors
for greatest range of mobility.
b. Since the unit utilizes infrared light reflected off of room surfaces, do not mount the
sensors near a black ceiling, wall, or heavy curtains as they may limit the range by
eliminating such reflection. Mounting the sensors in an uncluttered area near a light
colored wall will provide the best operation.
c. Although the unit can be used in most brightly lit rooms, it works best if bright lights
are not shined directly on the sensors.
(Note: Never operate the unit outdoors in
daylight as it will not operate properly under such conditions)
d. Never cover the IR Sensors as this will disrupt normal operation. If they become
dirty, clean with a soft cloth. Make sure the sensors are not obstructed and always
have a clear line-of-sight with the transmitters.
3. Additional external IR sensors can be added using the IRW-SA Multiple Sensor Adapter
which allows multiple sensors to be connected to each input.
