For my multichannel DAC I drew up this balanced line out with some added gain, using two halfs of a NE5532 set up as inverting inputs. It's mostly based on the GSSL output schematic, with the gain staging modified and an added input RF filter. I mostly wonder wheter I got the grounding right. DC blocking caps should be bipolar, but the PCB program didn't have those. The converter board is stereo, the analog grounds of the outputs on the converter PCB are already joined there. I could use only a single ground wire, but then shielded cables wouldn't work.
Thanks!
