Fig. 8b: Overlapping Illumination Patterns to Cover Larger Listening Areas
Fig. 8a above is a typical example of how multiple emitters are used to cover larger listening areas.
Generally it is desirable for the illumination patterns to overlap. Note: The coverage area will vary depend-
ing on the infrared receiver being used; refer to Figures 4 and 7 to determine how many emitters are
required to achieve full coverage of a listening area.
When two emitters are used at the same emission point in single channel mode, the overall coverage area incre-
ses 50%. When using an RX22-4 receiver, as a result, the coverage area will increase to an estimated 42,000 ft
2
(3,902 m

); the RX14-2 will increase to 5,250 ft
2
(488 m
2
); the RX18 will increase to 4,590 ft

(426 m

).
