Settings for Onkyo 807 after running Audyssey?

Check out a post by "kuntasensei" from 2-8-10.. this post go`s into detail everything you want to know about Audyssey.

Kuntasensei,

I haven't been near my Onkyo for over a year now...but concerning the PURE AUDIO setting...are you saying that Audyssey corrections are still operating in true two channel sound?

If so, at least any equalization introduced by Audyssey should be shut off in Pure Audio...no?

Are the volume settings unaffected? I honestly don't 'remember'??

Thanks..

Oh and i have Polk RTi A3 fronts, CSi3 center, RTi4 sides, RM6500 rears, and PSW- 111 sub. The room is in a basement 20Lx13Wx7H. The listening position is set up facing the width way in a 13x11 area. I watch black hawk down in 5.1 uncompressed PCM at -5db and it didn't seem excessively loud at all, i would expect it a bit louder at that level.

In my experience, PCM tracks typically seem quieter than TrueHD or DTS-MA tracks. Never figured out why, but it's true of every BD I've played that had PCM. As to the difference between digital and analog levels, I can't say, as I've never hooked up anything to my 1007 via analog. I'm letting my Oppo feed CD-audio, SACD, etc. digitally over HDMI. Still, I guess there could be a big discrepancy between the analog and digital levels. Intellivolume can help change each input to give you a more consistent level across all inputs.

You have solid speakers that should be pretty efficient, so they shouldn't take much to drive them to high levels. The only weakness I see in your system is your subwoofer, which sadly doesn't extend much deeper than your other speakers and is woefully inadequate for digital soundtracks because its -3dB point is 42Hz. You aren't getting any of the subsonic information that's in modern soundtracks. That could explain why you're having to turn the volume up so high to get the perceived loudness that you're looking for - your system can't play back the sub-40Hz audio that makes up a great deal of the visceral part of modern soundtracks. I guarantee you that if you had a subwoofer that hits cleanly down to 20Hz, you wouldn't be listening to the Irene chapter of Black Hawk Down at -5dB from reference.

Not having a sub that can go lower than 42Hz with authority also means that you're missing out on the advantage of Audyssey's DynamicEQ with respect to perceived loudness at lower volume levels.

The speaker trims are there to get all channels to reach reference when volume is at 0. The actual range of the volume control goes up to +18 with all channel trims zeroed, so there's still room above that and you're not at risk of overdriving anything. The question is mostly about what the line output power is of your CD player and the iPod... which you can vary with the volume control on the iPod, but unless your CD player has built-in volume controls, you're stuck with whatever its line level voltage is and will have to compensate in the AVR.

It certainly won't hurt anything if you have to set volume up near 0 to get decent levels in your room with analog inputs... but it is definitely unusual, and could make your system more susceptible to noise. What are you using for a CD player? And how do CDs played in your Blu-ray player via digital sound by comparison?

(But more than anything, I have to stress this: You need a better subwoofer, especially for that size area. Your current sub has neither the power for that size room nor the extension to fully reproduce digital soundtracks. Make your next upgrade a subwoofer from SVS, Hsu, or ED and I guarantee you'll put a big-**** smile on your face and any concerns about volume levels will be GONE.)
