Hey peeps!! I'm new to the whole AV game and have a few questions that i hope will bw answered... Firstly, and forgive me for being stupid, but what does my lfe attenuator do on my marantz amp? I see the term lfe being thrown round a lot!! Secondly, i have noticed that people with the same amp as me the marantz sr 4200 only have their vlume upto -10 maybe less, i put mine upto +5 (granted the walls are shaking) should it be this high? Have i set my speakers up wrong? Or am i just destined to make my ears bleed? I would be graeful if anyone could shed any light, no doubt i will have a few more questions in the not so distant future!! Cheers!!!
