Input / Output AC or DC Coupling

Hi,

Maybe my question(s) were not stated simply enough, so lets start here…
I know the Output is Balanced / Differential…
[b]Will the Output(s) of the uTrack 24 pass DC ?

Also, Is it possible to speak to the engineers who designed this unit directly via phone and/or email ?

Thank You Again Please !
