As suggested paired Aux1&2 in UC Surface talking to a 32r rackmixer, then used a Y cable (2 TS into 1 TRS) into my headphone amp.  Left and right channel are quite different volumes.

UC Surface running on a Windows10 Microsoft Surface Pro for mixing on the rackmixer.

Headphone amp is a 6channel Rolls unit so I tried other channels. same problem. Swapped cables. Same problem. Pan control on headphone amp is set dead center.  Also tried Aux out into wireless IEM - same problem. Tried other pairs of Aux (3&4, 5&6) etc.  Same problem.  Source material is not panned at all - should be centered. Not sure what else to check.  

I cannot find a pan control within the stereo aux pair - assume it just uses pan control from individual faders which are all set to center.

To check that the output works (and is balanced) yuo should have audio when using a 2-core cable.

earth is pin 1, and pin 2 and 3 is possitive and negative sound and if one of thouse isnt connected the volume is a bit lower..

I hope you understand and good luck!
