Hi

Ive just bought an 02R and it has 48 inputs plus another 8 analogues in an expansion slot round the back (fitted)

How do I assign any of the inputs that are not in the first 24 assigned to a channel so that I can hear them? (gone crazy with gear have way more than 24 outputs to use, want to use them all!!!!)

also, how do I assign channels to a group.

and yes, I do have the manual but I am being really thick...sorry!
