Reply to Do crossfaders affect my monitor output?

So, I just got a new A&H Xone22 mixer, and hooked it up using the separate monitor output (RCA) as my main, just so I could use it with the computer speakers I practice with. But both channels come through, moving the cross-fader has no effect. Is it supposed to be like that?? Doesn't that kinda defeat the purpose of having a monitor speaker in the first place?
