This may be a really stupid and ignorant question on my part, but as long as
the emu 1212 has balanced inputs, can't you use it with its balanced inputs
without the transformers? If they are good electronically balanced inputs
they mimic what a transformer does and break ground loops.
Usually you can go from unbalanced to balanced OK; it's the other direction
that may not work.
