While this diagram is generally true I think it should be explained that th=
is type of wiring would not be correct for Actively Balanced outputs.

Have a look here:

If you scroll down to the Active Balanced section you will read:

"When connecting an active-balanced output to an unbalanced load, it is nec=
essary to leave the cold output (pin-3) floating. Using an XLR connector, p=
in-3 should not be connected to anything. If a cable is used with pin-3 tie=
d to pin-1 (shield), the output amplifier could be damaged. This type of co=
nnection establishes a low/no impedance path to ground. This means the ampl=
ifier will drain current, unimpeded, into ground, which is stressful to the=
 output amplifier."
