My opinion is that if you mike the SS using 2 mikes (one for the front driver and one for the side driver) then you will end up with simply a Right and a Left channel which in turn can cancel each other out in the room. The advantage of the SS is that you have a Right + Left from one speaker, say the front driver, and a Right - Left say from the side driver. The only way to maintain this type of waveform technology is to always utilize the circuitry that is in the SS. Therefore.... only being to just let the SS do its thing. IF I remember right the pass through sends on the back of the SS can be used for the FOH, however I do not believe that the signals will be as R+L and R-L... Aspen is this correct? Please correct me if I am not right on this but I believe I remember reading about this a few thousand pages back!
