[QUOTE="Leroy Wiley, post: 216310, member: 14191"] Thank you, Mike. Correct me please, but a balanced line is 3 conductors, one of which is ground, and the other two are feed/return conductors. Right? So coming out of our X32 is likely an XLR balanced line connection - 3 conductors (I don't have the X32 in front of me to check). But currently, I am only using the white conductor as input to the amp via a Euroblock. You are saying I really should have all three conductors connected. I am going to assume if I trim back on that cable from the X32 I will find a black conductor in addition to the white one and the shield. So, looking at the back of my amp in the picture above it looks like the shield/ground should be connected to the rightmost pin of the Euroblock (rightmost as I look at the back of the amp ). Then the white to the positive (leftmost) and black to the negative (middle). Those are all questions, BTW. That is your recommendation one sorted if I have that all straight. Recommendation two is to feed channels 1 - 3 instead of 2 - 4 like it is now (the "pros" made that swap to 2 - 4 the last time they were out). And be sure all of the DIP switches are up. Is that DIP switch setting specific to the QSC CX254 or to QSCs in general and did you just know that off the top of your head? Thanks again. You can tell by my questions that I do not know what I'm doing so I really do appreciate the help I get from here. Besides the Pro Sound Training link above, are there other resources online where I can learn more? [/QUOTE]
