USB SECTION & PLAYBACK
1
USB Send Source Selection
The USB source selection switches determine which signals are
sent out on the USB interface. If all the switches are up the
main LR mix post-fade signal is sent. Other sources available are
the pre-fade main LR mix, Auxes 5&6, Auxes 1&2 and Matrix
1&2.
The switches work on a priority system with the upper switch
taking priority—so if all the switches are pressed in for exam-
ple, the Matrix 1&2 would be selected as the source.
