All,
I'm try to understand what is happening to my frequency response (and why) with Audyssey employed using a MultiEQ filter frequency range cutoff of 300 Hz (using the editor app). My understanding is no changes should be made above ~300 Hz when Audyssey is active, but I'm measuring what appears to be a ~1dB per octave filter applied above 1kHz (Stereo/Multi-Channel modes) when compared to measurements in Pure Direct (see image using psychoacoustic smoothing). I only captured the left channel for simplicity, but this is true for the right channel as well. Is there a setting that I'm missing that is causing this? My AVR has a "Cinema EQ", which is turned off. Thanks!
