Sorry, I actually meant an IMPEDANCE balanced output (old y'know and on meds) see...
impedance balanced output wiring diagram - Google Search
Since you know the source 'impedance' really a physical resistor most likely, you can put the same value in the pin 3 to earthy path.
There are swings and roundabouts to both systems. Pseudo gives good protection from ground loops but can be open to RFI. Impedance balance keeps the screen intact both ends. Would be needed for instance if phantom power was being used.
Transformers give both good ground loop protection and can give the very best RFI protection especially if good quality output traffs are used with 10k bridging transformers at the input end. They will of course be expensive if the very best sound quality is to be preserved.

thanks to the balanced outs of the M-512, it is a perfect match to the ICE16D in's.
the issue i am dealing with is the exact opposite - Taking the balanced outs of the ICE16D and getting 'em back to a console that lacks balanced line level inputs.
Do you recommend to use the psuedo-balanced cables, just the other way around?
or taking the balanced line level signals into the mic inputs?
