I have realized the behaviour of my receiver is different than I once thought. After going from an SR 6200 to an SR 7000, then an SR 8000, and along the way, testing an SR 6400 and SR 7400, I have been using it set to FRONT = LARGE and had the subwoofer connected to the front left and right pre-outs. I can't remember what I had the SUBWOOFER setting to, YES or NO, but it doesn't matter, since I watch movies in Source Direct. In Source Direct, regardless of the SUBWOOFER setting of YES or NO, the LFE goes to the subwoofer pre-out ONLY and not to the FRONT speakers and/or front pre-outs. I noticed that the SR 6400 and 7400 has SUBWOOFER settings of YES, NO and BOTH, but the SR 8000 does not have that. Anyhow... Here is my question: I have reverted back to FRONT = LARGE and SUBWOOFER = YES and I'm running the subwoofer off of the subwoofer pre-out. In Source Direct or normal, I get the LFE out the subwoofer each time. 1) Am I still getting some LFE out the front speakers with the FRONT = LARGE and SUB = YES when not in Source Direct? 2) What will happen to my bass and LFE when listening to non-DD DVD's? Will stereo and surround dvd's still allow bass out the Subwoofer output in Source Direct? In Source Direct, the receiver is supposed to simply pass the discrete information out the corresponding channels without crossovers etc. It seems obvious when the source is DD 5.1. I hear the fronts, the centre, the subwoofer LFE and the surrounds just fine in Source Direct. Just wondering how it works when I'm in Source Direct using a non-DD 5.1 soundtrack. I'll do some testing to see if I can figure anything out myself. I'm just wondering if anyone else has experience with this? My main question is whether I must dis-engage Source Direct in order to hear proper bass sound effects when not in DD 5.1. thanx P.S. Also, if I use SOURCE DIRECT or SUB = YES and there is a full LFE, that means the LFE is going only to the subwoofer, so should I leave my subwoofer crossover to 50hz as I've had it so far, or up it to 100 hz? I could remove the crossover in my setup but that would result in having no subwoofer volume control on the sub, making it next to impossible to calibrate the subwoofer and shakers separately. I'm not sure whether the subwoofer pre-out uses a 100 hz low pass crossover. I know the other channels use a 100 hz high pass when set to small, but I have never been able to figure out if the subwoofer uses a 100 hz low pass. Perhaps I should do some testing.
