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 receiver sensitivity and the reflection characteristics of the room.

Infrared light reflects off most surfaces and scatters, increasing the coverage area. Rough

surfaces tend to absorb infrared light, minimizing reflections, and limiting coverage to the

direct illumination pattern.

It’s helpful to think of the IR emitter as an invisible floodlight. You want to aim it so listeners

are “flooded” with infrared light.

It’s desirable for the illumination patterns to overlap when multiple emitters are used. Placing

the emitters high above the audience (15–30 ft./4-8 m) and aiming them slightly downward

(5°–15°) will ensure the longest “throw” of the infrared beam. Angling the emitter inward

towards the center of the room also increases the coverage of the seating area.

Remember: opaque objects block infrared light. Thus, emitters cannot be concealed behind

opaque walls, curtains, etc. Neither should emitters be used in areas of extreme high or low

temperatures, humidity, or chemical environments.

COVERAGE AREA

If you’re not getting sufficient coverage with a single, properly installed emitter panel, you’ll

need to add additional TX8 Emitters to achieve full coverage of your listening area.

Figures 3, 4, and 5 illustrate infrared light patterns and recommended emitter locations. In

listening areas up to 10,000 square feet (930 square meters), the TX8 Emitter panel should be

installed on the front wall of the listening area in a position to flood the listening area. It must

be above the audience to permit a direct line of sight between the emitter and people wearing

receivers when the people are standing or sitting.

Listening areas of more than 10,000 square feet (930 square meters) will require two or more

TX8 Emitters for complete coverage. Place one emitter panel on the left side of the front wall

and the other on the right hand side. For extremely large venues, additional TX8s should be

located to maximize coverage throughout the listening area.
