I've got a Pioneer VSX-D511-S hooked up to both my Tivo and my Panasonic E55. The speakers are a set of Eltax 5.1 that were aroudn £150-200 a year or two back. Whenever i'm watching either TV or a DVD and there is a quiet scene often the bass drops out and i'm left lsitening only to the satellite speakers, and when the bass kicks in again it might take up to a second - so if there is a quiet scene and then say a gunfight or explosion, or even a loud conversation i won't get anything from the subwoofer for up to a second. This happens more often when the volume is low - as if there is a threshold before the bass needs to kick in - so if the volume is set low there's more chance that the sound will be too low to kick in. Surely there must be a way to stop this dropout from happeninig - i have read through the manual and searched around on the net but i can't tell if it's a fault or if that's what happens on all receivers/subs. I'd hoped maybe i've set something up wrong and that disconnecting it all and the putting it all back might have fixed a dusty connection. Does a sub have to be fed with a certain level of signal or else it drops out ??
