[ICOM] ProII - true "dual audio"??

[Jerry K3BZ]

Does the ProII have "true dual audio"?  I know it has "dual watch" on split, but aren't those two audios mixed into one output?  Or are they separate channels that can be taken off separately, like in a stereo plug?

I'm asking because I'm considering the new Microham MicroKeyer II which reportedly will handle the second receiver audio in rigs that support dual receive (the original MicroKeyer doesn't).

I was thinking that what was meant was the dual radio arrangement like the IC-7800 has, two separate radios in one box.  Anyone have any ideas?
