John,

Agreed, I have no idea what internal changes would need to be made, if it is even possible, or if Meridian is even considering 5.1 analog. My original point was that the 562 is a lot more crowded than the 568. I did not see how it would be possible to add 6 more inputs to the 562, but changing functions is certainly a possibility.

But it seems to be moot, anyway, at least for this upgrade.
