I don't use the absolute reference scale for volume.. I use relative, which will give you an easier way to see the difference... in my setup, films on both DVD and BR usually are played at -4 and -8db (depending on codec mainly, but other things sometimes) and -25 to -18 for Directv...
Your center speaker is in a non optimal position.. while it may be ok for some viewing, being that close to the floor is sure to muddy up the waters in regards to dialog...
If it really is problematic in your room, and with how you hear and the volumes you are comfortable listening at, I highly suggest a couple of things..
1. Try Dynamic EQ and Volume / or Dolby Volume on the Onkyo for your BR input.. this will compress the dynamic range of the content....
2. Try "Late Night" mode.... this will compress the dynamic range of Dolby Digital / TrueHD content...
There's nothing wrong.. since we don't know your room or speakers, we can only assume that it's not optimal for high dynamic range content based on your observations... a center channel low to the floor is certainly not optimal, and there's only so much a flat response from Audyssey can fix...
I really think that Dynamic EQ/Volume will get it so that you can listen with a comfortable level while getting the best out of your room and setup.
Thank you for taking the time to explain things so clearly and offer such a detailed explanation.
I tried some of the things you mentioned and I can tell you several things.
1. I had actually discovered through trial and error a while back that Audyssey Dynamic EQ was the answer to the music problems I was having when listening to USB files containing songs with MP3, WMA, and WAV files. Using All Stereo mode with Dynamic EQ turned On with Dynamic EQ turned Off seems to be best.
2. When I listen to USB music without Audyssey Dynamic EQ, the Dolby Volume doesn't seem to do as good of a job, especially when I listen to any mode other than All Stereo. Simply put, anything other than All Stereo sounds vastly underpowered with the dialogue, even when Dolby Volume is turned On or when Audyssey Dynamic EQ is turned On.
However, turning Audyssey Dynamic on "Light" does SIGNIFCANTLY improve the dialogue from the Center Channel in Pro-Logic II when listening to USB music. I would go so far as to say that turning Dynamic Volume to Light makes it sound perfect -- just as good as All Stereo. In fact, if I have Dolby Pro Logic IIz Music on and then I switch to All Stereo, it is the Pro Logic II mode that actually sometimes sounds louder and more powerful. So, you were correct that Audyssey Dynamic Volume plays a large role (when it is set to Light). Any reason you know why this is?
My theory is that all those MP3 and WMA songs are recorded in stereo. Could it be that simple? The one reason why I would think otherwise is because I read reviews of certain Celine Dion songs where they said the standard CD in Pro-Logic II sounded just as good as a SACD. Those songs do sound nice in Pro-Logic II, but they still sound a bit underpowered compared to All Stereo mode why Dynamic Volume is not used. Any idea why?
3. Audyssey Dynamic Volume seems to really help things out while watching movies late at night when the volume is lower. If I set Dynamic Volume to "Light," I literally have to lower the Volume from about 35 to about 20, and I can actually hear things more clearly!
When I use Audyssey Dynamic Volume set to "Medium" these results are not as good; it is as if the power becomes reduced and it becomes as if the Volume is lower. And when I use Audyssey Dynamic Volume set to "High" it is as if these results are not even close to as good; it is as if the power becomes very reduced and it becomes as if the Volume is significantly reduced. Do you know why this is?
The bottom line is that "Light" seems to be the answer during times when I use Audyssey Dynamic, but it would help me out if I know "why" this is happening. Could anyone please take the time to explain what Audyssey Dynamic Volume is and how it is achieved. Perhaps you could do the same with Audyssey Dynamic EQ and Dolby Volume. I would like to hear your individual description on a personal level. But if you know of any links to descriptions, I would very much appreciate hearing them.
4. Here's something weird that I recently discovered. One of my favorite episodes of Transformers was on TV, so I decided to use my DVR to record it in high definition with 5.1 sound on channel 383 on Comcast. But, it was still set to record on channel 130 in standard definition with 2.0 sound. Channel 383 may "claim" it is 5.1, but in reality it seems to be a one-channel broadcast from the center channel. Channel 130 does broadcast a 2.0 signal in dual mono, which ends up producing a strong center channel signal by Pro Logic II. So, the channel 120 actually ended up with better sound. Do you think this is normal?
5. Okay, remember what I said in #4. Well, there was one other weird issue. I have my Crossover Frequency set at 50hz for all speakers. Even at that low of a Crossover Frequency, Audyssey Dynamic EQ being turned On with Dynamic Volume set to Off appeared to make it so the subwoofer was getting WAY too much bass (it just didn't sound right) while watching many TV shows on Comcast. When I grabbed the remote and turned Dynamic EQ to Off, the problem was solved and the subwoofer no longer received too much bass from the 5.1 source.
But when I watched that same episode from the 2.0 source, the opposite happened. Listening without Dynamic EQ produced a good signal without overpowering the subwoofer. But listening with Dynamic EQ turned On produced an even better signal with more power and it added to the surround effect from the other speakers without overpowering the subwoofer (what I had hoped would have happened from the 5.1 source on the other TV channel).
Any thoughts? I know the receiver isn't defective or anything in regards to #4 or #5, but I'm just wondering "why" this happens? That way I can apply the information acquired to other sources such as Blu-ray and DVD when I have some movies that are 5.1 and some that are 2.0. Any information would be greatly appreciated.
I'd like to thank all of you for your time and all of your help.
