The CR monitoring is pretty straight forward:
Ch 1 and 2 must be assigned to the stereo buss (in the output assign section).
Ch 1 panned left and ch 2 panned right.
Faders ch 1, ch 2 and stereo up to desired level.
In the Monitor section, select Stereo.
Make sure that the Mono button is off.
Make sure that the Talkback, Slate and Dim buttons are off.
You now should have stereo monitoring signals on the CR outputs and the two Phones outputs (turn Phones level up).
There are 6 user definable keys (Sel 1-6) that can be used to monitor different sources. They can be assigned in the CR Select part of the monitor screen.
