Balanced and unbalanced audio input connectors — Each input has a
3.5 mm, 5-pole captive screw connector for balanced or
unbalanced stereo audio input. Connectors are included
with each Matrix 12800 audio switcher, but you must
supply the audio cable. See figure 2-8 to wire a connector
for the appropriate input type and impedance level. High
impedance is generally over 800 ohms.

See figure 2-9 to identify the tip, ring, and sleeve when you are making
connections for the switcher from existing audio cables. 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, figure 2-8 and figure 2-10.

The audio level for each input can be individually set, via the front panel
controller or RS-232/RS-422, to ensure that the level on the output does not
vary from input to input. Refer to the Matrix 12800 Switcher Front Panel
Controller manual, and see chapter 3, Virtualization/Control Software, and
chapter 4, Programmer's Guide.
