Figure 2-4 shows two methods of wiring the captive screw audio connectors for input and figure 2-6 shows two methods of wiring the connectors for output. A mono audio connector consists of the tip and sleeve. A stereo audio connector consists of the tip, ring, and sleeve. If you are wiring a captive screw connector from an existing unbalanced audio cable, the white insulated wire is typically the left channel (tip) and the red insulated wire is typically the right channel (sleeve). There is no reliable standard for existing balanced audio cables.

The length of exposed wires is critical. The ideal length is 3/16” (5 mm).
•If the stripped section of wire is longer than 3/16”, the exposed wires may touch, causing a short circuit between them.
•If the stripped section of wire is shorter than 3/16”, wires can be easily pulled out even if tightly fastened by the captive screws.
