Select the outputs button below the touch screen.
select the tab for the MMO card I think it’s labeled slot b.
touch the Aviom connector on the screen and it will open a matrix box.
You can select from drop down menus and use input channels, mono aux, stereo aux, etc.
Pick the type you wish to assign and then choose the number.

for instance, pick the number one Aviom channel, then pick the type “input channel” then pick number 12. You have just assigned the direct out of ch12 to aviom output 1

hope that helps
