YOu'll only get balanced i-o on the first xlr in-puts,
and you can not have balanced i-o on rca jacks 'smile'.

I would try getting the correct cables so you can eliminate the
adapters, just to rule out one variable.
If you can get balanced cables, that might get rid of the hum
although it isn't a sure thing.
If you have Sound Forge, one of the EQ plug-ins has a preset for
removing hum that uses four stacked notch filters.
Do you have the Sonitus effects with your copy of Sonar? If so, use
the Sonitus EQ and set up narrow bands to cut at 60 HZ and multiples
of 60, 120, 180, etc. I doubt you're just getting the fundamental
at 60 HZ; usually there are some harmonics in there as well.
But, before filtering with software, which might negatively affect
the audio you do want to hear, try to figure out where the noise is
coming from and correct things there, with better cables etc.
