Cable Preparation for Audio Connections
The length of the exposed wires in the stripping process is critical. The ideal length is 3/16" (5 mm).
z If the stripped section of the wire is longer than 3/16", the exposed wires may touch,
causing a short circuit between them.
z If the stripped section of the wire is shorter than 3/16", the wires can be easily pulled out
even if tightly fastened by the captive screws.
Do not tin the wires!
Tinned wire does not hold its shape and can
become loose over time.
