ATTENTION:
• The length of the exposed wires in the stripping process is critical. The ideal
length is 3/16 inch (5 mm). If the exposed portion is longer, the wires may
touch, causing a short circuit between them. If the exposed wires are shorter,
they 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.
• For unbalanced audio, connect the sleeves to the ground contact. Do not
connect them to negative (–) contacts.
