However Atmos effects in content feel on the weaker side.Searching Google suggested that I should increase ceiling speakers level and keep other speakers same.
HERE is the question - if I manually apply gain and change the trim of ceiling speakers from -5.0 to say -3.0 or all the way to 0 (say), HOW do I know how much higher I can keep going from -5.0 until clipping occurs and I start to lose detail in overhead effects in actual content? If I'm applying gain on ceiling speakers from the set -5.0, where do I need to stop and how do I know the limit to which I can raise them before any sort of clipping would start to occur in content?
Your speakers will sound very distorted like their gasping for air. Clipping will occur when your AVR reaches it's limits which would require a fair bit of SPL. Try playing a different movie that has lots of atmos content. You can run your speakers a little hotter like +3/4dbs, but you don't want your setup out of balance either.
