Thanks for the replies, guys. Just to answer your question, I did remove the brass plates at the speaker terminals.
Gil,
Sorry if I didn't explain this too well. I have a Pioneer VSX-43TX receiver. It has 5 outputs on the A side, for the regular 5.1 setup. The receiver is also capable of THX 7.1. So the B side has a L and R out for the "surround back" speakers for that, if you want. I am also a technician, but I am not an audio technician. In fact, I had the most difficult time with transistors and amplifiers in school ;-) Anyway, I am trying to figure out if there's any benefit to hooking this up one way or the other.
I can get one set of bi-wire speaker cables. This has TWO terminals at the receiver end (black and red), then has FOUR terminals at the speaker end (red and black high; red and black low). I can use just one output of the receiver, and plug the bi-wire into both of the inputs of the speakers. Or, I can use two separate sets of regular speaker wires for the hook up. There are a few options I can choose from in the receiver settings for the B output. I can use it for the "surround back" speakers for the THX 7.1 field, or I can choose "Front bi-wire" where it sets the L and R out of the B side to send the same signal as the L and R out of the A side. So I have the L and R out of the A side hooked to the high in of both the left and right speakers, and the L and R out of the B side hooked up (through a totally separate set of speaker wires) to the low in of both the speakers.
I am trying to apply what I know about electronics to this situation, and it is just baffling me! I believe that receivers either have separate amps, or at least separate amplified channels for each output. I would assume that using two separate outputs would be easier on the amplifier in my receiver, as opposed to using one output that just has the wires split to go into two connections at the speaker end. So I was just wondering if someone could sum this up for me, and let me know if there's ANY difference in the two connections, and what a benefit would be from each one. If I am not getting a benefit from using the two separate pairs of speaker wires then I'd rather go back to using the bi-wire cable (less wire, and less hassle!).
Thanks again!
