Moog One Main Outs Issue?

Hello,
I have the 16 voice model. However, today out of nowhere, the main outputs stopped sending signal. I can’t figure out what I might have done wrong. Is there a setting that mutes the main outs or something? Maybe I engaged that by accident somehow. I get signal out of the sub outs and the headphone jacks, no problem. But the main outputs - which were what I used exclusively since I bought this synth a few months ago - just went silent a few hours ago.

Any ideas? Thanks in advance!
