On the odd occasion when I've been forced to feed an electronically
balanced output into an unbalanced input, I've normally done this by going
across Pin 1 (ground), and Pin 2 (+) But I've just come across an
electronically balanced device that seems to also short 1&3. Thought that
was bad practice or is it ok these days?

Other odd thing is the spec of this balanced output - it says output
impedance 200k ohms. Is that likely a misprint? The balanced input for the
same device says 50k ohms impedance.

Basically, it has both XLR and TRS jacks for output and reckons you can
simply use a 'mono' jack for unbalanced and shows that shorting 1&3.
