Question #1. My H/K 525 allows me to enter measurement values for Center, Surround, and Surr Back speakers. How in the world can this possibly work if the distance between the main speakers and the listening position is not known? Delay for all channels should be relative to the mains. There's no other way to do it. Does the H/K derive this distance from the center channel distance? That would mean that there is no center channel delay at all... only delay for the surrounds. Or does it derive the distance from the value you enter for the surrounds (distance "from the screen")? If so, then how could the surround delay possibly be accurate since it's not relative to the LISTENER? Question #2. These values are only adjustable for Dolby modes. Does this mean that DTS will use the settings entered in a Dolby mode, or does this mean that speaker delay is not used at all when playing a DTS source?
