Are you talking about the 9ch Stereo DSP? My understanding is this just takes the stereo source and maps it to the speakers you have. For my 2060, that is the center fronts and sides since I have a 5.1 setup. I don’t think there are any virtual speakers involved. It just means if I had the other speakers it would map that stereo source to all 9.\n\nOK, I had not really looked into this. What you say makes much more sense. So the OP is mixed up. His receiver does NOT create virtual speakers. That is impossible anyway and trying to do it would be a mess.\n\nSo the sound fades, when the phase differences try and send sound to speakers that are not there.\n\nHe can only set his AVR to the speakers he has. He can not try and recreate the effect of speakers he does not have. No wonder he has trouble.\n\nNow we have got to the bottom of it.
