Main output - XLR hotter than 1/4"?

Using on beta 2.0. My Main volume EQ in the master section is set to 0.0db and cabs are on and no "Link" selected. I used the Master Output on the back and connected both XLR and 1/4" jacks to test. The XLR line is louder to my DXR10 than the 1/4" TRS line. I'm using a high quality Mogami cable TRS jack.

Shouldn't they be the same volume since they use the same source and I'm using balanced cables?

I thought TRS (balanced) is the same as XLR? I understand TS is +16dBu.
