For larger facilities, an additional emitter can be used in order to increase the total coverage
area. The »PRO IR-202« is capable of driving another »PRO IR-202« in a combined mode as
a secondary emitter.
The coverage area can be adjusted to the according requirements, by setting the direction
of the secondary transmitter into the same direction, in sequence or in a different angle to the
primary transmitter.

Example: Two parallel placed emitters with overlapping illumination patterns to cover larger
listening areas.

Determine Coverage Area
When using the »PRO IR-202« transmitter in single-channel mode with the PR 22+ receiver,
the system coverage area will exceed 186 m². »PRO IR-202« units automatically adjust to give
the best coverage area possible in both 1-channel and 2-channel modes.
Figure 1 illustrates the typical coverage pattern for the »PRO IR-202« This can be affected by
direct/indirect sunlight, reflections on walls and room construction.
Reflections of the infrared light from walls, ceilings, and floors may change these patterns.
Important:
Remember to point the transmitter towards the listening audience.
Remember:
Most objects block infrared light. The transmitter cannot be concealed behind
walls, glass, curtains, etc. These patterns are the direct radiation pattern. The infrared radia-
tion 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.
The »PRO IR-202« can be operated with or without the faceplate, if desired. The faceplate can
be removed and painted to match the room decor. Lightly sand the face-plate with 400 grit
sandpaper, apply primer and two coats of the desired final color.
Do not paint the infrared lens behind the faceplate of the »PRO IR-202«!
