Can someone refresh my memory on how to create a ping pong delay on an SSL G board?

It's going to be with a mono track. I havent done this in a while. I've done it with a tape machine before but never using outboard gear. Im going to be using 2 lexicon pcm 42's.

For a 1/4 note ping pong, set both DDLs to 1/4 note, return each to its own input channel and pan them hard L/R. Feed the source to delay one, delay one to delay two, and delay two back to delay one.
