TX9 Emitter Setup
TX9 Location and Placement
To determine the best location for the TX9 Emitter, it helps to think of the IR emitter as an invisible floodlight. You’ll want
to aim it so the listeners are “flooded” with the infrared light. Mount the emitter at least 2 ft (.61 m) above the audience.
Position the emitter to face in a slightly downward angle - that will increase the “throw” of the infrared beam. 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. Remember: opaque objects block infrared light.
Thus, emitters cannot be concealed behind opaque walls, curtains, etc.
The emitter front red plastic lens must NOT be painted. Neither should emitters be used in areas of extreme high or low
temperature, humidity, or chemical environments.
The TX9 Infrared Emitter should not be installed where there is a lot of direct sunlight, which can create infrared
interference.
