CAUTION: For unbalanced audio, connect the sleeves to the ground contact.
DO NOT connect the sleeves to the negative (–) contacts.
NOTE: The length of the exposed wires in the stripping process is critical. The ideal
length is 3/16 inches (5 mm). If the exposed section is longer, the exposed
wires may touch, causing a short circuit between them. If it is shorter, the
wires can be easily pulled out, even if tightly fastened by the captive screws.
