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 signal 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.

(Range)

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.

Fig. 4: 3-Dimension Foot Pattern

Fig. 5: Vertical Beam Spread

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.

Reflections of the infrared light from walls, ceilings, and floors may change these patterns. 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: Overlapping Illumination Patterns to Cover Larger Listening Areas

Multiple Emitters Installed to Maximize Coverage

Fig. 7b: Overlapping Illumination Patterns to Cover Larger Listening Areas

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 depending 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.

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 ft

(3,902 m2); the RX14-2 will increase to 5,250 ft2(488 m2); the RX16 will

increase to 4,590 ft
