Depends where you take the signal from. See page 40 of the manual, which says:
Choose the global Channel Source for the selected
mix.
This is the point in the channel signal path that
feeds the mix.
This affects all sends to the mix.
Choose Post-Preamp if you want the sources to
the mix not affected by any channel processing.
Choose Pre-EQ for a monitor mix if you do not
want the channel EQ to affect the monitor.
Choose Post-EQ if you want the EQ but not the
compressor to affect the monitor.
Choose Post-All processing for FX sends.
So you want one of the first two options.
