Pro Logic IIx will deliver seven main channels for you, regardless of source, without any concern for whether it will sound "right" or "natural". And it will sound right and natural. Leave it at that.
Thing is, you need speakers - lots of them - to take advantage of this. The setup takes SEVEN speakers plus an extra one if you want bass.

You don't need a 7.1 setup for Pro Logic IIx. You need a 5.1 setup. 5 speakers and a subwoofer.

If you have six speakers and a subwoofer, like I do, it's even better.

And if you have seven speakers and a subwoofer, it's even better than what I have.

But the bottom line, is that if you already have a 5.1 setup in your house, then you simply need to upgrade your reciever to hear this.

It will take regular 2 channel stereo and convert it to either 5.1, 6.1 or 7.1, depending on whether you have a 5.1, 6.1 or 7.1 reciever and how many speakers you have hooked up.
