Infrared Transmitter, Model WIR TX90

NOTE: SPECIFICATIONS SUBJECT TO CHANGE WITHOUT NOTICE!

Fig. 4: 3-Dimension Foot Pattern

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.

(Range)

To determine the best location for the transmitter, it helps to think of the IR transmitter as an invisi-

ble floodlight. You’ll want to aim it so the listeners are “flooded” with the infrared light. The trans-

mitter 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 audi-

ence. Position the transmitter to face in a slightly downward angle, 20°, that will increase the

“throw” of the infrared beam.
