Bob: I have discussed this before with you on this forum, and I have something very different to report, and I think you can help explain it to me, because there definitely seems to be some issue with my D2v itself, or my mic, or files which came with the unit, because I just cannot understand.
If you look at my old post, you will see that I was trying to setup my system and the overall sound from my system was less than mediocre, and you suggested many things, and we went back and forth with lot of things but nothing really made any appreciable improvement.
I was basically using the setup method right out of the book, and some things you had suggested in the beginning of this thread. Do the speaker distance,…… set the test tone level,……set the sub level with the volume knob on the sub itself etc. etc., except that I was really not able to tell the difference in sound when I turned the phase knob on my Paradigm Sub25 (because sound really sucked), but other than that, it was pretty much out of the book.
Couple of days ago I just saved user settings and loaded factory defaults, and just did some basic setup, like speaker distances, and source setup to use HDMI out from Oppo 95 so that I can start playing something, and this is where it gets interesting and baffling at the same time.
The only thing I did is to go under Bass Management Movie and tried two setups, one Adv Settings ON and one Adv Settings OFF, and as you know, it sets all five speakers and sub to 80 THX crossover when the settings are ON. When I have Adv Settings ON it shows that Sub Polarity is Inverted (by default, is that right?), and Sub Phase is defaulting at 15 degrees (is that right?). I would expect the Polarity to be Normal, and Phase to be zero. I have ARC OFF under source setup. It sounds better with Adv Settings ON and with ARC OFF (Dolby Vol is always OFF). Sound is just awful with ARC ON, not so bad with ADV Settings OFF.
I have two few questions; first, why it is defaulting Polarity to Inverted, and Phase to 15 degree (I did try to change Polarity to Normal, and Phase to 0, but it sounds better with where it is right now, not a huge difference but still). I would expect Polarity to be Normal, and Phase to be 0. Now here is the interesting part; my system is sounding amazing with these settings, it has never sounded this good, I can leave it where it is, sure, but I know by reading what all you guys have said that it can sound better if my ARC can really do its thing. Believe me when I say this that there is a day and night difference in the sound I have right now with the settings I described above and the sound I have (had) with ARC engaging and all that good stuff. It is so much more open, and clear. The only way I can define the sound with ARC on and other good stuff is the sound you get with a towel thrown on the speakers.
My next question becomes what’s wrong; I don’t believe that my ARC procedure is incorrect, then is it the microphone, or something more than that, I have no idea, but I would surely like to get to the bottom of this, so please let me know what do you think on this issue. I am thinking there is some hardware issue, it might be the microphone or something in the D2v itself. But at this point I am at least enjoying very good sound from my system, may be not the best possible, but it never sounded this good.
Another thing I would like to know is that you have always said to set the Polarity on the sub itself, but if D2v setup has those settings then why not use those, it is lot easier to change those settings sitting at your listening position rather than have someone else do that what you try to listen for the peak volume. My sub does not have Polarity setting on it, so please tell me why we should not use Polarity and Phase under D2v setup itself. Thank you very much.
