To attach stereo audio input wires:

Insert the wires (for wire placement for balanced and unbalanced audio, see FIG. 104) and firmly
re-tighten the clamps to make secure connections.

Balanced & unbalanced stereo audio wiring
Note: For stereo audio signals using twisted-pair wire, connect the shield (ground) only at one
end (recommend receiving end) to minimize low frequency noise (FIG. 105).
Wiring Sources
Source devices will require either balanced (differential) or unbalanced (single-ended) connections.
Options for wiring between the sources and the input connectors are illustrated in FIG. 105. More than
one of these options can be used in the same system. For balanced and unbalanced wiring details, see
FIG. 104.
