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
3b 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.
Minimum receiver RANGE when operating with a TX8 or TX10 transmitter in Single Channel Mode.

The TX10 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 signal strength of the receiver being
used. Refer to Figures 2 and 4 to determine
how many emitters are required for 100%
coverage of the listening area.
