I have some questions:
1. I did the initial setup with YPAO (as per instructions, I set the volume of the sub in the middle "0" and the crossover to 160Hz , that is the max). It set the distance at 3.5 mt (which is correct), with a level of -1.0dB (which I set to "0") and the crossover to 160Hz (which I set to 100Hz...am I wrong?). What should I do to optimize my subwoofer?
2. How the "Dialog Lift" should be set? For now I left it to "0", because (ignorantly) I thought that the voice should clearly starting from the center channel underneath my television.
3. As for the parametric EQ , YPAO set it to FLAT...should I set it to NATURAL to improve the overall sound?
4. If I wanted to raise the level of the subwoofer should I raise it directly from the sub, as it is now to "0", or raise the level of dB from the speakers manual configuration?
5. I connected a WDTV Live for watching contents in 480p/576p/720p, and for now I have set in the menu VIDEO PROCESSING the DIRECT MODE. If I would set to 1080P would see better quality?
6. In the speakers manual configuration, YPAO set the distances and levels in the same way between left and right side (FL and FR are both set to +1.0dB, SL and SR are both set to +3.0dB), but if I go to Parametric EQ and go to MANUAL SETTING (where you can see graphics), the values are different from left and right (Example: left is +184.5 and right is another value). Is it ok or is it something wrong?
I can try to answer some of these.
1. I'm surprised it didn't set the subwoofer distance a bit further than it actually is to account for delay within the subwoofer. In any case, I would take what YPAO set for distance even if it's further than the sub actually is. As for the level, you can adjust it up if you like more powerful bass. My feeling is that YPAO sets the sub very low (or I just like more bass).
If YPAO set the crossover to 160 Hz, it must be because your speakers do not have sufficient output below that. That's very high, in my opinion, but if you reduce it and your speakers can't fill the gap between 100 Hz and 160 Hz then you have a gap in that range in the sound. That would be a bad thing.
EDIT: The specs for the Canton Movie 70 claim a frequency response of 120 Hz - 25 KHz for the satellite speakers. I'm not sure whether the 120 Hz is the -3 dB point or something else. It seems that YPAO isn't happy that the speakers can reproduce frequencies below 160 Hz, though. I definitely wouldn't set the crossover to 100 Hz, because at the least you'll have a gap from 100 Hz to 120 Hz. I suspect the gap is even larger, though. I'm not sure I'd go below 140 Hz for the crossover.
2. Ideally, it should seem like dialog is coming from the TV screen where the people are speaking. Dialog lift can be used to make up for the fact that most center channels are below the TV. I think the lift works better if you have presence speakers. In any case, do what you feel sounds best.
3. Choose the YPAO curve that you like best. For the Flat curve, YPAO attempts to make the response of your system flat across the full spectrum, thus reproducing sound as closely as possible to how it was mixed. Natural rolls of the highs a bit, which some people find harsh. Natural may be a bit of a warmer sound. Pick the one you like.
4. I like to control the sub from the AVR settings. However, I know that I want to run the sub a little hot, so I turned up the sub before running YPAO so that YPAO would set it to -4 dB or so. Then I turned it up to somewhere around 0 dB to +1 dB in the AVR.
5. Does your TV upscale? Most newer HDTVs do. Mine does, and I compared it to the AVR's upscaling. I found that the TV did a slightly better job, so I don't have the AVR do it. Also, I don't like how the AVR menu gets laggy when it's processing video (and I think there are some things you can't do, I don't remember all the details).
6. You can see the levels for Flat, Front, and Natural, too. You can even change them if you want. I have a 773, and that's the case for me. Did you copy anything into Manual (like Flat or Natural)? If not, where did the values in the Manual setup come from? My guess is that they are meaningless (I'm also guessing that +184.5 is a typo). You can start by copying one of the YPAO curves like Flat or Natural into Manual, and adjusting it to suit you (if you aren't happy with the YPAO curves as they are).
