The reason why I set my sub vol at 50% is that as the output of the sub is dependent on LFE input, that will not be any 'distortion' if the LFE input signal is too large as some movie do have very large LFE output. Ehhhh! Can understand what I meant kar?

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% ). So that is why I set my sub vol at 50% & let my avr control the LFE signal.

BTW auddsey set is being done but it can control the LFE output so that it 'balance' with the rest of my 7.2 system. Also even though it is at -15db ( two set up with diff sub vol at 40% & 50% ), the auddsey set the LFE out put differently.

Actually when I read through my post I also don't understand what the poke I am writting about..........dam my english very bad!

Yes all the 7 spk match in their output after auddsey setting has being done, measured my spl meter. Both sub output at same level measure with spl but the actual vol on the two sub is different due to distance & different brand. Paradigm is set at 50%, Velo SPL 1200 at 65% due to its low output & distance.

Ok one time I try to say why I set sub vol at 50%........

Assuming u set the sub vol at 30%, ur avr will of cause increase ur lfe level to -10db. Now when u watch movie with lotsa of LFE at high vol ur avr will also increase it LFE output to the sub. Now due to the restriction of the sub at 30% level it can only produce its LFE to 30% only. So while ur other spk will be at very high output ur sub output can only be at 30% level ( due to the vol being set at 30% ) also in this case distortion might set in at the sub woofer due to high input LFE since u r now listening ur avr at high vol.

Due to this reasoning I set my sub at 50% level ( any higher the avr will warn u that sub vol is too high ) & so far I have not detect any bass distortion.

Hopefully can understand now hoh?

So far I have not done manual setting ( too lazy to measure the spk distance ) 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.

Added on October 28, 2009, 4:50 pmAh! Finally someone do understand what I am writing about!

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?

Tq very muck! Now I understand what is a 'gain control'.

Not mine at the moment.........still under 'review'.
