Since I am really newbie, I am asking this silly question, please do not lough at me. My mains are 200 watt, surrounds 200 watts and center is 100 watt. I plan to buy a new receiver Arcam 300/250 or Denon 3805. Since the power of the speakers are different than the each other (center and the others), how can I adjust the output of the receiver for each speaker? Or is it necessary to adjust each speaker output seperately? I do not blow my center speaker.
