bda-s4 boost only 12x 484095-001-00 Boost 32X Part of it because of the splitter . if you need better boost -lrb- and only use single tv -rrb- , choose 484095-001-00 . if you need splitter and do not need so much boost you can go with bda-s4 Wish BDA-S4 have more boost . maybe 20x . it will be great
