COVERAGE AREA

Determine the coverage area needed for the seating area. When using the TX9 emitter with the

RX12-4 receiver, in single channel mode, the TX9 can achieve a coverage area of 28,000 ft

(2,600

). In four channel mode, the TX9 divides its power among the four signals to achieve a coverage

area of 11,000 ft

(1,022 m

). NOTE: The coverage area will vary depending on the sensitivity of the

infrared receiver being used. The following diagram illustrates coverage area when using a RX12-4,

RX14, RX14-2, or RX16 receiver with a single TX9 emitter in single channel mode.

These patterns are the direct radiation pattern. the infrared radiation does not drop to zero outside the

illustrated patterns; it decreases. It still may be useable at a greater distance, depending on the

receiver sensitivity and the reflective characteristics of the room.

Reflections of the infrared light from walls, ceilings, and floors may change these patterns.

Important: Remember to point the emitter towards the listening audience!

Remember: opaque objects block infrared light. Thus, emitters cannot be concealed behind opaque

walls, curtains, etc.
