yes, you will have to stick to trim if the FOH guys are in charge of gain. Although it seems to be more common practice for MON to control gain, leaving the FOH guys with trim.
No audio passes through the ipad, everything goes into or out of the idr32. But PFL for outputs can be activated from ipad. FOH will activate pfl for inputs from surface. This is all configurable depending on available outputs.
All controller units connected to idr 32 operate independantly so they can all work indepentantly.
How do you have 40 channels on your idr32?
