mono delay

yikes....hi guys did a search and for the life of me I can't seem to get a mono delay setup on the kemper
I'm using the spdif out to my soundcard
I think I picked free delay like a thread suggested but still no luck

how do I do that?!!? it still seems I had ping pong going on

when I look under free delay all i see is
mix
time
ratio
feedback
bandwidth
center frequency
modulation
ducking
volume

where do I find both delays!?!?

Quote from Trazan

Ratio. Needs to be the same on both sides, and modulation needs to be off.

ok so ratio would be 4:4?
thanks for the help!
