Audyseey Dynamic EQ on or off??

felipe

Hey y'all. Does anyone have any experience with Audyssey Dynamic EQ?? I know what it is supposed to do, but I was wondering if I changed the speaker trim levels would that effect it? I'm thinking of upping the trim levels as follows:

FL (-5.5 to 0 )
FR (-6.0 to -0.5 )
C ( -6.5 to -1.0 )
SW ( -7.0 to -1.5 )

Im keeping the ratios between the channels the same to maintain the balance obtained when running Audyssey. Does anyone that have this feature here even use it?? I find it makes some material rather unnaturally bass heavy. Would changing these levels affect how dynamic eq works??

I have it and I use it.

Its nice to be able to toggle it on and off.

Mainly I keep it on.

Those trim levels seem low to me. You won't hurt anything by experimenting with the speaker levels, try it and see what sounds best to your ears.

I should ask what your crossover frequencies are for your surrounds, and if your listening in "All Channel Stereo"

I found if I ran my LSi setup (15's, C, F/X) full range then it got boomy, but crossed at 80 (fronts at 60) they are fine, even with all channel stereo.

All channel stereo also adds a bit more bass since all channels are getting the same signal rather than either own discrete mix.

Those trim levels were set by the audyssey auto-cal. Of course those values were set b/c audyssey sets according to reference level volumes ( 0db ). Who listens to reference levels at home?? I sure don't.

My main question is if I up the trim levels will it screw up the dynamic eq correction? If I do, will I even need to use dynamic eq??

I got my xover points at 60 fr the mains and 80 for my center. For movies I use the auto decode and for TV I use pro logic II cinema.

I would recommend against messing with the trim levels. Audyssey sets those trim levels based on your room and in such a way so that 0 on the MV would correspond to reference. Adding a constant amount to all channels should be like bumping your volume up by that amount so it has no real benefit.
All of what Dynamic EQ does is that it boosts the low end. I don't like what it does to the sound so I usually turn it off and turn up the subwoofer trim by 3-5 dbs which sounds better to my ears.

Those trim levels should not a problem as long as they are within the adjustment range which in this case they are.
If for example a receiver can adjust from -12 to +12 and it sets the trim level to -12 that means that it is possible that the receiver was trying to go to something lower than -12 and it couldn't so it settled for the lowest amount possible.

That's what I thought at first. Just to verify, I contacted audyssey directly. They said that by using the dynamic eq reference level offsets ( which I completely forgot about ) it would be OK to up the trim levels without **** up dynamic eq function. Example, if I up the trim levels by 5 db then I_would set the reference level offset at 5db...and dynamic eq function will operate correctly. Who knew?? Going to try it out..see how it goes....

I increased the trim levels by 5db and set the offset at 5db...voila! Not only does it get louder, but to my ears the sound is more dynamic and clear. As far as the bass...its just as powerful but not unnaturally bass heavy..more defined and clear. Now I don't have to set the master volume as high now...guess that might explain the more dynamic sound. To anyone that has issues with dynamic eq...give this method a shot. It works...at least for me it did.
