Just run their outs (using insert cables) to the command station and 
then out to your amp/DI box(es).

Actually in that case you wouldn't need an insert cable.  Just a 
balanced (stereo) one will do.  But you need to do some soldering.  
Disconnect the wire going to the ring and leave it like that, and 
then disconnect the tip and connect it to where the ring is.  So you 
should just have the ground connected, the tip connected to the ring 
(with the previous connection to the ring NOT connected), and nothing 
connected to the tip.
