This is not acurate. The 7.1 input is the only one that is 100% analog. The four analog stereo inputs are digitized, since the bass management is done in DSP. As a proof, have the FM tuner play or any of the four analog stereo input selected, hit the Info button and look closely at the display. You will see "PCM" appear briefly. FM is as analog as it gets, so if the processor sees it as PCM, you can be sure that is because it was digitized!
