Hey everybody, as you can see im extremely new to this forum, so hopefully its not too much of a problem i just made my account and am already making a thread but im having a major issue I have a panasonic 42' 1080p plasma, Pioneer Vsx-519v-k receiver with a ps3 and xbox 360. The setup seemed so easy! im running HDMI out from the 360 and ps3 to the TV inputs. Then, going Optical out to the receiver, and then Subwoofer Pre-out to my Klipsch sub. Im getting fine audio out of my infinity towers, but im getting almost NOTHING out of my sub! i can turn it up all the way (actually being 11 in this case LOL) and i get a very small bit out. Enough to tell its definitely on, but its a wisper. I previously had it set it very differently and far more complex including running audio through the separate audio for the ps3 and 360, an external audio switcher, to an EQ, and THEN to the receiver and it seemed to be fine somehow, but im not sure what i did that fixed it or if im missing something in that loop that i did. Ive tried hooking up an mp3 player to the switcher, to the EQ and then into the receiver but still now bass.am I being silly with something im doing here? any help would be appreciated! I thank you all so much!!!! *edit* i figured out how i had it set up before. Basically i was giving the Sub full range cause it has right and left inputs. Its a powered sub and it has its own speaker ports and everything. Its a Klipsch ksw12, any ideas from anyone? Problem solved! see post 7 if your having a similar situation, thanks again guys!
