Figure 2-4.B shows three methods of wiring the stereo connectors, with input
examples across the top, output examples below.
Figure 2-4.B
Three ways to wire stereo input and output audio
connectors (see cautions below).
When making connections for the Matrix 6400 Audio switcher from existing audio
cables, see Figure 2-4.C. The round audio connectors are
shown with the top one (tip and sleeve only) for
unbalanced audio and the bottom one (tip, ring and
sleeve) for balanced audio. The "ring", "tip" and "sleeve"
markings are also used on the captive screw
audio connector diagrams in Figure 2-4.C.
Together, these examples may be used as a guide for
making audio cables.
CAUTION
Do not connect equipment that uses phantom power.

CAUTION
Connect the sleeve to ground (Gnd). Connecting the sleeve to a negative
(-) terminal will damage the audio output circuits.
CAUTION
There is no physical way to prevent you from plugging a stereo audio
connector partially in one input and partially in the adjacent input. This
could cause circuit damage.
