MTP AV Series • Installation 8
CAUTIONS:
• The length of the exposed (stripped) portion of the copper wires is important.
The ideal length is 3/16 inches (5 mm). Longer bare wires can short together.
Shorter bare wires are not as secure in the direct insertion connectors and
could be pulled out.
• The captive screw audio connector can easily be inadvertently plugged
partially into one receptacle and partially into an adjacent receptacle. This
misconnection could damage the audio output circuits. Ensure that the
connector is plugged fully and only into the desired input or output.
NOTES:
• When making connections for the MTP using existing audio cables, see
figure 10 to identify the tip, ring, and sleeve wires in various connectors.
• A mono audio connector consists of the tip and sleeve.
• A stereo audio connector consists of the tip, ring, and sleeve.
• The ring, tip, and sleeve wires are also shown on the captive screw audio
connector diagrams (see figure 9 and figure 17).
