Hey thanks guys for the responses, but does the lfe then need to be set in the (-) zone for less bass. Mine ranges from -10 to +10? The D. Range Comp also has several settings including max, so I take it that basically the closer settings to min would mute more sound..and as I go toward max, I get more thump? Also, what does the "effect" setting do? Am I playing with equalization or what? Psych
