Description:
The TX90 two channel IR transmitter combines modulator and emitter technology into a single operating unit, which
reduces operating cost and eliminates precious rack space. The TX90 transmitter produces a wide-angle infrared sig-
nal that concentrates the IR energy efficiently in the listening area. Operating on the 2.3-3.8 MHz bandwidth, the
TX90 is less susceptible to radio and lighting interference. Each TX90 transmitter can cover up to 28,000 sq ft (2,600
sq m) in single-channel operation. The coverage area can be easily increased by connecting additional TX9 emitters.
A wall/ceiling omnidirectional mount is included, and stand kits are available for portable operation.
Applications:
Cinemas • Simultaneous Interpretation • Audio Description • Conferences • Multi-Media Rooms
Boardrooms • Courtrooms • Schools • Universities • Churches

The coverage area for the TX90 will vary depending on the receiver being used. The diagram
above demonstrates the receiver coverage when operating a single TX90 transmitter in single chan-
nel mode. Patterns are direct radiation patterns.
Note: Reflections of the infrared light from walls, ceilings and floors may change these patterns.

Fig. 4: 3-Dimension Foot Pattern
The TX90 floods the listening audience with a
cone shape light pattern as shown here.
The path of the cone shape light leaves a
pattern on the ground, or "foot print, " and
indicates where the strongest receiver
reception will occur.
The actual coverage area will vary depending
on the sensitivity of the receiver being used.
Refer to Figures 3 and 6 to determine how
many emitters are required for 100% coverage
of the listening area.
To determine the best location for the transmitter, it helps to think of the IR transmitter as an invisible
floodlight. You’ll want to aim it so the listeners are “flooded” with the infrared light. The transmitter
should also be positioned high enough so it won’t be blocked by people and other physical obstructions.
See Figure 5 below. Mount the transmitter at least 2 ft. (.61 m) above the audience. Position the transmitter
to face in a slightly downward angle, 20°, that will increase the “throw” of the infrared beam.

Important: Remember to point the emitter towards the listening audience!
If you’re not getting sufficient coverage with a single, properly installed TX90 Transmitter, you may need
to add additional WIR TX90 Transmitters to achieve full coverage of your listening area. Figures 7a and
7b illustrate how multiple emitters can be used for large room installations.

Fig. 7a above is a typical example of how multiple emitters are used to cover larger listening areas.
Generally it is desirable for the illumination patterns to overlap. Note: The coverage area will vary depend-
ing on the infrared receiver being used; refer to Figures 3 and 6 to determine how many emitters are
required to achieve full coverage of a listening area.

(50% increase)
When a TX90 transmitter and TX9 emitter are used at the same emission point in single channel mode, the
overall coverage area increases 50%. When using an RX22-4 receiver, as a result, the coverage area will
increase to an estimated 42,000 ft2 (3,902 m2); the RX14-2 will increase to 5,250 ft2 (488 m2); the RX16 will
increase to 4,590 ft2 (426 m2).
