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).
• If the stripped section of wire is longer than 3/16", the exposed
wires may touch, causing a short circuit between them.
• If the stripped section of 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.
NOTE: Audio ground pins may be labeled as
or . The wiring and function are the same,
whichever way your product is labeled.
7. Connect the appropriate input or output devices to the front panel connectors.
8. Test the system and resolve any cabling or signal issues.
