The audio level for each input can be individually set, via the front panel or
RS-232/422, to ensure that the level on the output does not vary from input to
input. See chapter 3, Operation, chapter 4, Programmer's Guide, and chapter 5,
Matrix Software for details.
Connections for audio outputs — These 3.5 mm, 5-pole captive screw
connectors output the selected unamplified, line level audio. Connect audio
devices, such as an audio amplifier or powered speakers. See figure 2-7 to
properly wire an output connector.

Unbalanced Output
Connect the sleeve to ground (Gnd). Connecting the sleeve to a
negative (-) terminal will damage the audio output circuits.
By default, the audio output follows the video switch. Audio breakaway,
commanded via the front panel, under RS-232/422 control, or Windows-
based control program, allows you to select from any one of the audio input
sources. See chapter 3, Operation, chapter 4, Programmer's Guide, and
chapter 5, Matrix Software for details.
