Audyssey set all my speakers to around -10 db

why does Audyssey set all my speakers to around  -10 db, will adjusting the up  to around the 0 mark but keeping within the specified adjustments ruin the calibration.

    Because it is trying to: (1) make all speakers play at the same level and (2) make the system play at film reference level when the master volume is set to 0 dB. 

    The individual speaker levels are just relative number to achieve the goals above.  If the speakers have high sensitivity and the listening distance is close then the levels will be set as you see them.  This is not a problem in any way.

    Sorry i understand its trying to level the volume across the speakers, but why all speakers around the -10 db, and not around the 0db mark,

     If they are left at -10 db i have to have the amp running  high say 55 volume, but if the volume is set around the 0db mark the volume say only needs to go to around 40 say.

    so if the audyssey selectss say

    center -8db   and i change to say 0db

    fronts -8db and i change to say 0db

    rears -6db and i change to say +2

    sub -6db and i change to say +2

    will it ruin the audyssey, all the setting i have adjusted are still the same levels wise.

    Because if the speakers in your room and at your listening distance were set closer to 0 then you would be listening louder than film reference when the master volume is at 0 dB!  This way we set the speakers to the exact sound pressure level used in the studio so that when you turn the volume down Dynamic EQ can properly make the adjustments needed.

    Yes, if you raise the levels then Dynamic EQ will not be calibrated correctly.  There is really no difference whatsoever if you have the trims down to around -8 and you listen at a higher volume.  Turning up the trims is *identical* to turning up the volume control--and everything remains calibrated.

    Hi chris sorry im i bit slow, im on about adjusting the level calibration,so if i alter them up but still keep the same gaps between the speakers i wont be calibrated properly.

    like my setting above as both ways are identical.

    also some films i have to turn the center speaker up alot does this not affect the calibration then.

    also what do you mean by trims.

    Trims are the individual levels of each speaker.  It's a bad idea to change them because (1) it makes no difference to the overall level--it's the same as turning up the volume control and (2) it messes up the Audyssey Dynamic EQ calibration

    so adjusting the sub or the center will make calibration void to then is that correct.

    also what does the inteligent volume do if i left them set up at the - levels and adjusted the intellegent volume bu +10db would that muck the calibration up.

    "void" is too strong of a word.  It makes the perceptual adjustment by Dynamic EQ not be perfectly correct.  It has no effect on the acoustical correction made by Dynamic EQ.

    Intellivolume is a fancy name for a simple input gain adjustment.  It is used to minimize the difference between two different sources.  Not all that useful and also could lead to misalignment.

    ok chris thanks, just redone the clibration but if i turn it upto say 50 i can hear hissing in the speakers if a pause it it goes, didnt get this before,

     system play at film reference level when the master volume is set to 0 dB,

     what is 0db on an 606 volume wise. how can i tell what the loudnees is supposee to be set at.

    Onkyo has a relative and absolute volume mode setting.  You can select in the menu.  0 dB in one mode is reference and 83 dB (I think, please check in the manual) is the reference in the other mode.  They simply use a different way to report the volume control setting.

    HI chris, cant adjust it on the 606, but i have just been sold that before setting the audessey up select a volume level say 40 on the amp and that becomes your refrence point then so when the audessey does its thing, 40 becomes the studio refrence point.

    is this correct.

    No, there is no such thing... I wonder where all this "information" comes from... The studio reference point is at a given sound pressure level.  Audyssey sets the speaker levels so that you can listen at studio reference when you turn the master volume up to 0 dB.  Make sure your volume control is in that mode (Onkyo provides two different modes to present the numbers).

    Hi chris, i only have the choice of Absolute with the 606, which i why i thought that selecting a volume refrence point before calibration made sense, as if i set it at volume 40 then i know when i turn it upto 40 thats the studio refrence pojnt.

     

    so it does not matter what volume i have set be it ten or 80 it will give the same result and i will not know where the refrence point volume is.

    OK, on the TX-NR606 the volume control can go from 1 to 79, right?  Onkyo defines the reference listening volume at 63 on that scale.  MultEQ sets the speaker levels so that at volume setting 63 you are listening at studio reference.  That will be pretty loud for most people.  So, we developed Dynamic EQ.  Once you turn the volume down from there, Dynamic EQ starts making adjustments to preserve the proper low and high frequency balance.  That's why it's important to not change the individual speaker levels.  It will throw off the Dynamic EQ calibration.
