This is probably going to sound pretty silly, but here goes. I'm switching to a preamp/poweramp setup for the first time (once the units arrive) this week and I have a question on how everything connects together. I'm sure the manuals will explain, but I want to try to have all the right cords I'll need ready and waiting. So here it is...I'll have a Sansamp RBI and a QSC RMX 1450 with an Avatar 410 and 115. I'll probably want to run it bridged mono to ensure proper headroom against the two guitarists with their full stacks. Exactly what sorts of cables would I need to purchase to set everything up correctly? I'm clueless about "speakons" etc. as I've never had to use them or have owned anything with them. From what I've gathered along the way in reading various posts that mention them they're a bit different from the usual 1/4" inputs. Or are they? Sorry for the newbish question. But I'm entering a new realm of amplification here. Any advice or suggestions on setting this up, or alternate configurations is appreciated.
