FIG 12: 3-Dimension Foot Pattern

The TX9 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 11 and 14 to determine how

many emitters are required for 100% coverage

of the listening area.

(Range)

To determine the best location for the 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. The emitter

should also be positioned high enough so it won’t be blocked by people and other physical

obstructions. See Figure 13 below.

Mount the emitter at least 2 ft. (.61 m) above the audience.

Position the emitter to face in a slightly downward angle, 20°, that will increase the “throw” of the

infrared beam.
