Thanks for both of the responses. I have made good use of the trim function and was also able to boost the keys using the direct out level.
I have another question that is kind of related. The lead singer doesn’t use the aviom so I have Aux1 setup for a monitor for him.
I have my whole gain structure set and all the channels switched over to use trim which doesn’t affect the Avioms but does affect his Mono Aux1 monitor.
I am thinking there is no magic this surface can do about this so I will have to first adjust the trim and once that is right mix his monitor. Any ideas?
Depending how many channels you are using you could mirror your channels and mix the Aux1 send from the second set of channel strips (essentially what I do if I’m doing a mains/monitor setup with my system). To set this up just select a second set of channel strips & set the input on those to mirror the channels required in his foldback - make sure you also set trim on surface on those strips!
