CAUTION

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, the Ethernet link, or the RS-232 link, allows
you to select from any one of the audio input sources. See chapter 3,
Operation, chapter 4, Programmer’s Guide, chapter 5, Switcher Software, and
chapter 6, Ethernet Operation for details.
