Usually you can use them as unbalanced. In some cases this
requires a special cable, but that's unlikely.
What seems weird with with this box: it has a
word-clock out but no
word-clock input.
Not a real one, but it will sync to SPDIF or ADAT.
What is not clear to me is
if the balanced I/Os are [or can be] ground-lifted.
Better not. Ground lifting can damage your inputs unless
1. the inputs are physically isolated by a transformer
(not the case),
2. the common mode voltage (the difference between the two
grounds) is small.
Unless you have transformer isolation, you need a more or less
common ground. And then, if the inputs are really balanced and
you use balanced cables, there is no need to lift the ground.
