Well after a few months reading reviews and listening various demos I have bought myself a shiny new home cinema system, a B&W MT-30 speaker package with an Onkyo TXSR875 amp and Pioneer PDP 4280 flatscreen. Im really pleased with everything but would like some help setting up my PV1 sub. Do I select 4Ohm or 6 Ohm in the setup for the speakers and what do I set the controls to on the sub itself? So far Ive just run the auto setup with the mic supplied but cant help feeling im missing out by not making manual adjustments. Im afraid Im new to all this so not sure what to touch! Also Im currently feeding the component video output from my old dvd player through my amp and upscaling through the hdmi to my tv, is it worth doing the same with my sky HD feed which I have going straight to the tv at the moment? Thanks
