This could be the stupidest question I've asked on here yet but here it goes. When I run Audyssey it puts my LCR speakers at -12 so at the suggestion of many people on here I bought 12db attenuators. My question is does the attenuator get plugged into the receiver or the amp? Does it matter which way the signal is going? I'm just not sure where to put the pointy end of the attenuator!!
