C Input connector — This 3.5 mm, 5-pole captive screw connector accepts line level
balanced or unbalanced, mono or stereo audio signals (see to the illustrations below for
proper wiring).
ATTENTION: The length of the exposed wires in the stripping process is critical.
The ideal length is 3/16 inches (5 mm). Any longer and the exposed wires may
touch, causing a short circuit between them. Any shorter and the wires can be
easily pulled out even if tightly fastened by the captive screws.
NOTE: Do not tin the wires. Tinned wires are not as secure in the connector and
could be pulled out.
