Should be able to go from guitar signal > mixer in (say Channel 1 for fun) > FX level on the mixer for that particular channel (if allowable on your board) or on the master channel > back to your board/amp.
Plug in the digidelay etc and whatever else into the FX send/return of the mixer.

My pedalboard costs approximately 191 Metal Zones.
Simple run the delay full wet with effects after it and blend your guitar signal in. If you want the effect to be applied over and over to the repeats put the delay and effects in a feedback loop to ger your repeats.
