By default, the audio gain of each output is set to 0 dB (unbalanced) and 6 dB
(balanced). To reduce this setting by 6 dB (-6 dB [unbalanced], 0 dB [balanced]),
see “Setting the default audio gain” in chapter 6, “Upgrades and Maintenance“.
By default, the audio output follows the video switch. Audio breakaway,
is available via the front panel, either RS-232/RS-422 port, or the Ethernet
port. See the Matrix 12800 Switcher Front Panel Controller User Guide, and
see chapter 3, “Virtualization/Control Software”, chapter 4, “Programming
