SoundPlus™ Infrared Listening System
System Overview
The WIR TX90 two channel infrared transmitter combines infrared modulator and emitter technology into a single
mountable enclosure - reducing operating cost and eliminating precious rack space.
The WIR TX90 features an easy to use conguration preset for Music, Voice, or Hearing Assistance Applications. It
operates on dual 2.3/2.8 or 3.3/3.8 MHz selectable frequencies - ideal for high quality audio programs such as music,
theater and audio description. The WIR TX90 will accept any line level, balanced or unbalanced audio inputs, and
includes adjustable tone and volume control. Infrared receivers detect the transmission and convert the light signals back
into audio signals. The 2.3-3.8 MHz operating frequencies minimize high efciency lighting interference. No FCC license
or radio approval is required with this equipment. It can be used anywhere in the world.
NOTE: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant
to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment. This equipment generates, uses,
and can radiate radio frequency energy and, if not installed and used in accordance with the instruction
manual, may cause harmful interference to radio communications. Operation of this equipment in a residential
area is likely to cause harmful interference in which case the user will be required to correct the interference at
his own expense.
NOTICE: A plasma monitor can degrade the audio quality of the SoundPlus™ Infrared Listening System.

Determine Coverage Area
Determine the coverage area needed for the seating area. When using the WIR TX90 transmitter with the RX22-4 receiver, in
single channel mode, the WIR TX90 can achieve a coverage area of 28,000 ft2 (2,600 m2). In four channel mode, the WIR
TX90 divides its power among the four signals to achieve a coverage area of 11,000 ft2 (1,022 m2).
NOTE: The coverage area will vary depending on the sensitivity of the infrared receiver being used. The following
diagram illustrates coverage area when using a RX22-4, RX15-2, or RX18 receiver with a single WIR TX90
transmitter in single channel mode.

These patterns are the direct radiation pattern. The infrared radiation does not drop to zero outside the illustrated patterns; it
decreases. It still may be useable at a greater distance, depending on the receiver sensitivity and the reective characteristics of
the room.
Reections of the infrared light from walls, ceilings, and oors may change these patterns.
Important: Remember to point the transmitter towards the listening audience!
Remember: opaque objects block infrared light. Thus, the transmitter cannot be concealed behind opaque walls, curtains, etc.

Selecting a Carrier Frequency
The WIR TX90 offers two sets of carrier frequencies for Channel A and Channel B:
2.3 and 2.8MHz or 3.3 and 3.8MHz.
The WIR TX90 is preset to 2.3 and 2.8 MHz, which are the most commonly used. Move the slide switch to select a pair of
operating frequencies.
Selecting a Channel
To activate a channel, press the “CHANNEL” button until the channel “ON” indicator lights. For example, to operate only channel
A, press the “CHANNEL” button until only the channel A “ON” indicator lights. To operate both channel A and B, press the
“CHANNEL” button until both “ON” indicators light.
Note: If you’re only using one channel, make sure the other channel is turned off to maximize system coverage.
MAN 119H

Page 8
SoundPlus™ Infrared Listening System
Select the Audio Processing Application Preset
The WIR TX90 offers three preset audio processing options for the most common applications: Music, Voice, and Hearing
Assist. Use the “Music” setting when maximum dynamic range and audio quality are preferred. Use the “Voice” setting for
simultaneous interpretation, audio description, or other applications with users that have primarily normal hearing. Use the
“Assist” setting for hearing assistance applications to meet the reduced dynamic range needs of hearing impaired listeners.
You may select the same audio pre-set for both Channel A and Channel B, or you may select them independently.
To select the audio processing preset, you must rst activate the channel you want to adjust. Press the “channel” button to
activate the channel(s) you want to choose an audio processing preset for, then press the “Presets” button to choose the
preset. The Music, Voice, or Assist indicator will light to show your selection. After 10 seconds, the setting will be stored.
Adjusting Audio Input Level
The TX90 is designed to accept a line-level audio input signal. The “Level” indicator light for each channel is used to help
adjust the audio input level. When the indicator does not light, the input signal level is too low. When the indicator is ashing,
the signal level is optimal. When the indicator is steadily lit, but does not ash, the input level is too high and can cause
distortion. You can adjust the input level of both channels simultaneously, or independently.
Make sure the input audio signal is connected to the WIR TX90. To adjust the audio input level, rst activate the channel(s)
you want to adjust by pressing the “CHANNEL” button, then press the “VOLUME” button. The Volume indicator will light.
Now, turn the “ADJUST” knob clockwise to increase the input signal or counter-clockwise to decrease the input signal until
the channel “Level” indicator is ashing. After 10 seconds, the setting will be stored.
IMPORTANT
Audio level NORMAL (optimal): the audio indicator level will flash at a 1 second rate.
Audio level too HIGH: the audio indicator level will stay on or flash erratically.
Audio level too LOW: the audio indicator level will be off.
Adjusting Tone
The WIR TX90 has a tone adjustment to suit user preference and to compensate for the different frequency responses of
various infrared receiver models. First, make sure the audio source is active. Use a receiver from the system to listen to the
signal as you adjust the tone control.
To adjust the tone, rst activate the channel(s) you want to adjust by pressing the “CHANNEL” button, then press the
“TONE” button. The tone indicator will light. Now turn the “ADJUST” knob clockwise to emphasize high frequencies (best
for hearing assistance use). When you have reached the maximum adjustment, there will be no further change in tone. Turn
the “ADJUST” knob counter-clockwise to decrease the high frequency emphasis. When you have reached the minimum
adjustment, there will be no further change in tone. After 10 seconds, the setting will be stored.

Using the Optional WIR TX9 Slave Emitter for Additional Coverage
For larger facilities, additional emitter panels can be used to increase the overall coverage area. In these cases, we recommend
using the WIR TX9 slave emitter in tandem with the WIR TX90. The WIR TX90 can drive multiple WIR TX9 emitters at one time.
Each TX9 emitter will require its own power supply.

Trouble Shooting
The WIR TX90 “Power On” indicator is not lit.
• Make sure the transformer is plugged into the transmitter and any remote power switch is on.
• Make sure the electrical outlet is on.
• Make sure the 24 VAC power supply is working.
The WIR TX90’s channel A or B “On” indicator is not lit.
• Make sure the desired audio channel has been activated. See Selecting a Channel on page 7.
• Make sure the WIR TX90 is plugged in.
• Make sure the audio input is connected properly. See page 6 or instructions on the back of the WIR TX90.
• Make sure an active audio signal is being sent to the WIR TX90 transmitter.
No sound through receivers.
• Check to make sure the receiver is operating on the same frequency as the transmitter.
• If some of the receivers work but others don’t, check for bad batteries or earphones on the receivers that aren’t working.
• If none of the receivers work, check to see if the power and audio input cable are connected to the transmitter and that the
WIR TX90 “Power On” and Channel A or B “On” indicator is illuminated.
• Check to see if the transmitter is connected properly to the sound system. The audio level indicators should ash on channels
that are selected.
• Make sure the “eye” is not covered up on the receiver. There must be clear line of sight between the receiver eye and the
