The OctoPre inputs get routed to both the lightpipe AND the analog outputs so you can use both(on the one you are patching via lightpipe) so those analog outputs can continue on to the PA console. You may have some other options as well. If the PA console has inserts on the channels, you can often tap the pre-EQ signal from the insert jack. Many consoles have direct outputs on each channel as well. Also(this will sound like a curveball so think about it) you don't have to patch inputs 1 for 1(bass drum might be channel 1 on the PA but can be any number going into protools) so you could patch 8 channels using the lightpipe Octopre(with the analog outputs feeding those signals to the PA) and then run seperate microphones from the stage for some stuff(maybe the PA uses an SM57 on guitar but you could use a nice ribbon or condenser for recording). Once you get your head around all the possibilities, you'll find lots of options.
