how can I listen to post processing action(effects) in live?

hello,

I want to listen to the effects I add to my chanells in cubase in live action, before I am recording.
example - xlr + microphone are connected, than I want to sing and listen to my voice
with reverb, or even an eq changes. how can I do that?

my audio card is - m-audio project mix I/O

I tried to disable direct monitoring on my audio card and inside cubase (device setup-> vst audio system ->
uncheched direct monitoring), and than I added effcts and eq changes on the input channe on cubase
and also in the monitor chanel, and even on the master channel.
but stil after that, I heard the same unprocessed signal that came directly from my audio card.

any solution?
