That's not what he was asking...
Yes you are correct, you'll have 2 CDJ's connected up with Audio to the DJM-800's 2 channels (say 1,2). That means you can't map those channel controls in ableton, because they will also affect any audio coming in from the CDJ's.
The third input could be from your soundcard (And ableton)... this means that you also can't map the channel controls for that third channel (the eq's, volume fader, etc) in ableton either, as you'll affect the audio (if you change an eq, for example) coming into the Ableton channel.
The fourth channels controls could then be used for pure MIDI control.
BUT... what happens if you want to play multiple channels in Ableton? You will probably want to be able to Cue the audio, right? So you'll probably want another output from ableton coming into the mixer so that you'll be able to cue and such. Therefore that fourth channel isn't going to be free for long.
See, this is why the DJM-800's MIDI is really not adequate for use as an Ableton controller if you intend to mix decks and software.
You end up just using the mixer, well, as a mixer... and doing the MIDI control elsewhere (though there are a few more buttons on the 800 that aren't in the mixer section you can map to various functions in Ableton).
If you look at A+H's Xone 3D, you see that they realized this. They keep the mixer portion essentially separate from the MIDI portion, with appropriate connections between the two (Soundcard routes to the mixer, etc.).
