I would like to downsize my Verona 480 by removing the mono input channel banks on either side of the desk. Can this be accomplished simply by disconnecting all the ribbons to the modules? I would also like to replace one bank of mono channels with a stereo (multi-function) channels. Would this be a simple swap out? On paper it seems like an easy mod but I want to check first in case it will mess with power distribution since the 480 has dual power supplies.
