Why don't you think this is a grounding issue? This is a classic setup for a ground loop. Many A/B/Y boxes have one output transformer isolated for just this reason. Some unsafely use a 3 to 2-prong adapter on one amp. I use a HumX ground lifter on one amp when doing this, and I recommend the HumX as a very useful tool in general for a gigging musician.

I agree this has all the indications (and IRL sounds like earthing/mains hum) of an earthing loop being created.
However, I am experiencing an identical problem feeding the outputs from the DL4 to a Hot-rod deluxe and Tech 21 - Trademark 60 combo, left and right channels respectively.
Now this is the puzzle - THE Tech21 has a ground lift facility but this DOES NOT eliminate the ground loop/problem ? Any thoughts anyone ?
PS Can anyone help with my recent question about pages 12-33 of DL4 pilots manual ?

hey guys i hvae a dl4 going into a pod x3 pro rack unit and same problem. it may be a ground issue howeer even with a ground lift off of the power supply does this no justice. so whether i am using both inputs on the pod or one input to the pod and one too an amp while recording it hums loudly. i've tried different cables, ferrite beads etc. and nada, which sucks using stereo delays which are fun......
hey line 6 fellas what up.
