UR22mkII Unbalanced Output Only?

Hey everyone! I was trying to get balanced audio out of my UR22mkII earlier today and for the life of me couldn’t figure out how to do it.
I used a TRS cable plugged into the back of the interface and I checked the signal with an oscilloscope: the tip was the left (or right, doesn’t matter) mono signal, the sleeve was ground, but the ring was also ground for some reason.
Does this interface not output balanced audio for monitors?
