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.
