2 Channel, 1 nW/sq cm per channel
(Approx. 18000 sq ft, 1700 sq m)
4 Channel, 1 nW/sq cm per channel

Reflections of the infrared light from walls, ceilings, and floors may change these patterns.
Important: Remember to point the emitter towards the listening audience!
If you're not getting sufficient coverage with a single, properly installed TX9 Emitter, you may need
to add additional WIR TX9 Emitters to achieve full coverage of your listening area. Figures 8a and
8b illustrate how multiple emitters can be used for large room installations.
