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.5.1.4 Dolby Atmos setup with ceiling speakers. Second such setup, the receiver software set the four ceiling speakers trim to -5.0 dB. Problem is the overhead effects feel weaker in actual Atmos content compared to my last setup.I also have an SPL Meter, I verified that I am getting about 75dB at MLP 0 with all speakers at the LP with the set trims. 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?
