Use the "Split Out" feature of the Shure PSM-200'S P2T Transmixer to send one mix from your console to both P2T's. For example, input the aux buss on your mixer that has a band mix to the Input 1 of the first P2T. Connect Split Out 1 to Input 1 of the second P2T. From your mixing console take an output of the vocalst(s) and input that into Input 2 of the first P2T. Then from the mixing console, take an output of the guitar(s) and connect that to Input 2 of the second P2T. Now, each receiver that is tuned to the first P2T can listen to a combination of band plus vocals and each receiver that is tuned to the second P2T can listen to a combination ofband plus guitar(s). Adjust this concept to your own situation. For example, you may want to blend in some vocals into that band mix. The Split Out is an important tool for configuring a two transmitter (transmixer as Shure calls it) Shure PSM-200 system.
