The Meridian Installation Guide of my G68XXV says that the five Toslink inputs are stereo. I am, however, sending a 5.1 audio signal from a Sony PS3 and a LG TV satellite/Cable receiver to these inputs (Q1 and Q2). Is the Meridian better than its guide says or are we processing a 2-channel input signal back to multichannel in the Meridian`s DSP? Is Toslink audio transfer limited to 2, 6, or 9 channels?
