Hey Everybody! I've always had a 700RB-II, but recently purchased a NEO212. I got the speakon cable to utilize the bi-amp functionality. My question is this: Do I need to use both the speakon AND the 1/4"? I assumed I'd just need the speakon, but there was no sound until I plugged in the 1/4" with it. Any light you can shed would be greatly appreciated! Bonus: I'll also take any tips/suggestions for the EQ/bi-amp setup!
