Default Threshhold 400A

I'm connecting a Rel subwoofer to the output posts on my Threshold 400A and the way it is to be connected depends on whether the amp is common ground or diff balanced. Can someone answer this for me so I can wire it correctly. Thank you.

Looks like common ground to me but be your own judge.
