Thanks UD and Gord, for the explanations.

Gord, that would be cool if I can stand that mixer on its own, cause right now I am using one of my keyboard (quick lock, double tear) stands, and that was the one I used for gigs. Now I am taking out my ultimate, which is heavier to carry around.

One note, it turns out the power amp that has the A and B, is actually 600W per channel a total of 1200W (I was excited to read that on the back of my amp).
Also my powered monitor is 300W, and I think the QSC amp is like 200W per channel (not sure about that yet).

I hooked up the powered monitor and it works fine.
I have also been able to use the effects processors with my mic.
I guess I will purchase that manual and figure it all out the right way.

Thank you all for the help.
