M-AUDIO Super DAC - Manual (Page 6)

Now let’s go a little deeper. What if you have a few different pieces of digital
audio gear? Let’s say you have a pro DAT machine with AES/EBU digital out,
a computer sound card with S/PDIF. Your CD Player actually has a TOSLINK
optical out, and you think you could improve its sound quality by replacing its
built-in D/A converters with something more "high end." The solution is to
hook all three to the Super DAC’s inputs, and use the front panel Format
button as a convenient source selector.

Then there are the outputs. Both the balanced and unbalanced outs are always
active, so let’s use them. Perhaps you have a power amp with balanced inputs,
and then a cassette recorder that you’d rather send a signal to directly.
