Schematic for XLR/balanced line driver?

..for what is worth...there is also something called impedance balancing, where you only feed signal on the hot side and has the other side ( the inverting side )being the same output impedance. often just using a resistor to ground.  That way, even though there is no signal in the inverting line, it picks up the same noise as the noninverting, resulting in canselation of cablenoise.
many times when you see small inexpensive mixers and they say something like "all outputs are balanced" this is how they do it. you loose 6db compared to active balancing but it does work...

Right you are Johan, and that link from MikeB shows the details under 'cheat'. I was just meaning, tying one side to ground & just 'doing it', like when there is an emergency (the show must go on)
That balancing  cheat is a pretty handy trick!! thanks everyone!
