CInput 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.
