Important: To determine the correct wiring to use for the audio connectors, check the type of
connectors specified under each module illustrated in the figure on page 124 and in the table for
AF-10 boards on page 125. If the model is listed for balanced audio, it may also be wired for
unbalanced audio (FIG. 90). If the model is listed for unbalanced, it can only be wired for unbalanced
(FIG. 91).
