To all Elites,
I am setting up my system by using SPL meter. After running the manual setup and adjusting the level trim on the amp side, my front(L&R), centre, rear and sub are now at the respective level, -2.5, -1.5, -1.5, +3.0. All these level are set at 75-78db. I am wondering whether they looks ok?
I had someone to set up my system using SPL meter before I change my front speakers and the level trim on the amp side was front (L&R)~+10.5, centre~+4.5, rear~+8, sub ~+5....these level were set at ~80db.
It seems to me that, the different is huge! So approximately what did you guys get for the level trimming on the amp side?
Thank you.
So far I have not done manual setting ( too lazy to measure the spk distance I am setting up my system by using SPL meter.

) but base on auddsey set up the spk measurement is very accurate. I only use the spl meter to do some very minor adjustment in the sur spk.

Ummm.... I think I understand what you're trying to say. 
Well, Audyssey will compensate for your sub volume. If you set your sub volume very high, then Audyssey sub trim will be set very low (-15 dB is lowest). Conversely, if sub volume very low then Audyssey will boost the sub trim (up to +12 dB max I think). So really it doesn't matter what is your sub volume as long as you don't reach the limits of Audyssey because then you go beyond the ability of Audyssey to compensate.
What you said: "Ok it is like this.........LFE input very large so by right ur sub output will be large but it can't output that very that much as it is being restrict by the vol control ( eg at 30% )" I don't think is correct. The sub vol control is a gain control, i.e. it multiplies the input signal from the AVR. So if you set at 30%, Audyssey will boost the signal (to compensate) so 30% x boosted signal = 50% x lower signal. Like I said earlier Audyssey will compensate so that some balance is achieved.
Ah! Finally someone do understand what I am writing about! Well, Audyssey will compensate for your sub volume.

U r correct that is what I meant..........Now all this time I assume our sub vol or better know as gain control also act as sort of a master vol control. Correct?
