Analog audio connectors
See figure 9 to wire a connector for the appropriate input type. Connectors are included
with the MediaPort 300, but you must supply the audio cable. Use the supplied tie-wrap to
strap the cable to the extended tail of the connector.
NOTES:
• The length of exposed wires is important. The ideal length is 3/16 inch (5 mm).
• If the stripped section of wire is longer than 3/16 inch, the exposed wires may
touch, causing a short circuit.
• If the stripped section of wire is shorter than 3/16 inch, wires can be easily pulled
out even if tightly fastened by the captive screws.
• Do not tin the power supply leads before installing them in the connector. Tinned
wires are not as secure in the connector and could be pulled out.
An unbalanced stereo audio connector consists of a tip, ring,
and sleeve. An unbalanced mono audio connector consists of
a tip and sleeve. When you are making connections for the
units from existing audio cables, see the drawing at right to
identify the tip, ring, and sleeve parts of the connector. The
ring, tip, and sleeve wires are also shown on the captive screw
audio connector diagrams, figure 9 and figure 10.
