Audio outputs connectors (TPX 88 A only)
The Audio Outputs connectors are 3.5 mm, 5-pole captive screw connectors that
output unamplified, line level audio. The local audio outputs
follow the RJ-45 outputs; that is, if input 6 is tied to output 1, then
audio output 1 is the input 6 audio.
Connect audio devices, such as an audio amplifier or powered
speakers. See figure 2-5 to properly wire an output connector.

CAUTION
Connect the sleeve to ground (Gnd). Connecting the sleeve to a negative
(-) terminal will damage the audio output circuits.
The audio level for each input can be can be individually set, using the front panel
or under RS-232/RS-422 control, to ensure that the output level does not vary from
input to input. See chapter 3, Operation, chapter 4, Programmer’s Guide, and
chapter 5, Switcher Software for details.
By default, the audio output follows the video switch. Audio breakaway, which
can be commanded via the front panel or under RS-232/RS-422 control, allows you
to select from any one of the audio input sources. See chapter 3, Operation, chapter
4, Programmer’s Guide, and chapter 5, Switcher Software for details.
