Hot Gossip about Sound United and Dirac

[PENG]

I saved it from a discussion post. A couple guys were talking about the effects of Audyssey and what DEQ does. Iirc this was taken directly from the preouts, but not sure what the signal feed was. I like to share it whenever I can because it’s easy to just say DEQ is just a bass boost or similar, and it’s not really that simple. It’s also nice to illustrate how the contour changes as you get closer to MV-0, which can also give an idea about how RLO works too.
I don’t use DEQ because I use my own house curve(although I have off and on in the past), but the biggest problem for me is how it boosts the surrounds and rear heights/tops.

Thank you for the clarification. I might have saved the original set published by Audyssey but it would be a tough search and time consuming to find it in my saved document among so many hard drives I have.

I listened to 60 to 75 dB average spl watching movies so I have to use DEQ and hated the surround boost too. The boosts to the surrounds and heights, if I remember right, started later, perhaps around 2015. They might have quietly addressed that via FW updates (mine is the 2017 AVR-X4400H), as I don't seem to be bothered by the boosts any more and I don't think it's because I got used to it.
