Hi, I was over at my fathers today, where he has a Kenwood 409 (last years version of the 509, without DPL2 basically) ANyway, he's had it about a year, but when I check it, I realize the entire time he's owned it, his center has NEVER worked, he just didn't know better (he got it as a casual thing, not as a enthuiest) and it seems the guy who sold it and set it up said the center isen't always making sounds, only on special parts does it kick in, much like surrounds not always having sound coming to them.... Which is stupid, because there are no voices or the like... And, even though all his connections are perfect (I unhooked and redid everything myself) the reciever always displays the center as "downmixed" to the fronts... The front three speakers are "A" and the rears are considered "B" via their hookup to the back. When A+B are on, the center is downmixed, and the rears work fine. When only B is selected, the rears work, but not the front three (obviously, they are set B). But when A only is picked, both fronts AND the center work perfect.... Turn back on B, and bang, the "downmixed" lights up and the center channel is sent to the mains once again. I checked the setting, and reread the manuel about 50 times, but it doesn't even list the downmix "feature" let alone how to disable it. In the setup menu, the center is set as normal (though I set it to large to try, still nothing) and he has no sub. The distance's and levels are all balanced, but I adjusted all to their extreme's to see if anything would change, though still nothing, the DVD player is a JVC XV-45 and it's hooked to the reciever via optic cable. Can anybody explain what exactly is going on with this, he has had his 5.0 setup for almost a year, but hasen't had anything but 4 speakers work for the entire time, not realizing how much is supposed to actually come from the center, so he didn't suspect anything was wrong. Any help is much appriciated.
