Slightly OT - balanced to unbalanced cables?

[Jezz Brookes]

Apologies if this is slightly off-topic but does anybody know how to wire a
balanced to unbalanced cable. I've just bought a compressor with balanced
XLRs and need to patch it into my system which is all 1/4" mono jacks.
Somebody said to bridge pins 1 & 3 together, but I'm not sure if this forms
the Gnd or Signal. I remember seeing some design that included a small (200
ohm?) resistor as well. Any clues?

Thanks.

Jezz.
