Routing

I think it's the other way around.

Think of it this way:  The mixer is the owner of the sound, you are sending sound out from the mixer in to the DD7 (to manipulate it) and then bringing it back in to the mixer to send it out from your master channel. 

If that's confusing, here's the short version:

MIXER'S SEND --to--> DD7 INPUT

DD7 OUT   --to---> MIXER RETURN

Don't forget to turn SEND/RETURN ON on your FX dial.

thanks,

its work but the sound go very low , not same normal effect 

Do you have the dry/wet all the way to wet? other than that, I have not touched my DD7 in a long time but look for a gain on it and if not, then i guess that's it.

Cheers
