FIG. 15b: Overlapping Illumination Patterns to Cover Larger Listening Areas

Fig. 15a 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 depending on the infrared receiver being used; refer to Figures 11 and 14 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 increses 50%. When using an RX12-4 receiver, as a result, the coverage area will

increase to an estimated 42,000 ft

(3,902 m

); the RX14-2 will increase to 5,250 ft

(488 m

); the RX16

will increase to 4,590 ft
