best way to connect babyface to 2kxl

I've recently got a rme babyface and I'm wondering about connecting it
to the babyface. I know that my mpc has balanced ins and unbalanced outs.
So usually I would go from my mixer to the ins of the mpc. If I was to record a wav from my laptop thru the babyface I'm unsure what cable to use as the manual states:

Low impedance line outputs do not operate servo balanced! When connecting
Unbalanced equipment, make sure pin 3 of the xlr is not connected. A connection to ground will cause a decreased THD

Can anyone explain this

Also as the outs of the mpc are unbalanced will this create an issue connecting it to balanced inputs of the babyface breakout cable? I mean should I be lookin for balanced or unbalanced 1/4 to xlr.

Thanks guys that's exactly what I did. I was pretty confident about it till I read the manual of the babyface an got a lil confused. Gonna test out the babyface later expectin a bit of a difference comin from 2 track recordins from a £20 behringer sound card haha
