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 TX90 Transmitter, you may need to add additional WIR TX90 Transmitters to achieve full coverage of your listening area. Figures 7a and 7b illustrate how multiple emitters can be used for large room installations.
