when u use thx settings, do u set all the speakers to small be4 running ypao? in the manual it said that thx speakers should be set to small but i dont know if its true for regular speakers. i have a back surround sub hooked up, what are the best settins? i have large mains and center and sattlelites surrounds connected to a sub. i set it using ypao, the settins were all over the place. please reply with some recommendations. i use it to watch dvds most of the time and music sometimes. y would u use both as lfe outputs?
