Ideal positions
The best result is achieved when placing the transmitter in a position where it can transmit to
the receivers unobstructed, as illustrated in figures B) to E).
Important: Direct the transmitter towards the 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. Reflections of the infrared light from walls, ceilings, and floors may change these
patterns.

microphones (or high impedance condenser microphones) to the "MIC-IN"- ports.
The incoming microphone signal can be mixed with the main audio signal.
