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.
