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.
D Output connector — The 3.5 mm 5-pole captive screw connector outputs balanced or
unbalanced audio signals (see the illustrations below for proper wiring).
ATTENTION:
For unbalanced audio output, connect sleeves to the center ground
pin. DO NOT connect sleeves to the negative (–) contacts. This would create a short
and possibly damage the unit.
NOTE:
Do not tin the wires. Tinned wires are not as secure in the connector and
could be pulled out.
