Hey there Jack, what a prescient question
so you can connect up to 2 wireless transmitters, and they replace up to two of the analog XLR/line inputs when connected (you essentially choose 'wireless' as the mic type rather than condenser, dynamic, Podmic, NT1, etc).
They have full access to all the same processing that any XLR/line device would have, so all the VoxLab, granular processing and effects, and the RCP/Duo master processing! Wonderful, right?
