OK I broke down and installed 4 height channels. So my system currently consists of ; Marantz AV7704 11 channels of amplification ranging from 200 - 500 watts per channel at 8 ohms Various speakers, 5 of which are home made. Xfinity X1 and Sony DBP-3370 Blu-Ray player. I intend to purchase the Sony UBP-X800M2 when it becomes available, but for now, I would like to hear the height channels do something other than "All Channel Stereo." Does the Marantz sound processor have an option to convert 5.1, 6.1 or 7.1 audio movie sound tracks into 7.4.1? If so how do I enable it?
