This will work fine with a regular (but DUPLEX) soundcard, i.e. most $40-50
soundcards, but based on your mixer, you may need some matchboxes that do
impedance and level matching for you.  The soundcard in most pc's (unless
you spend big $$$ for a pro one, which I recommend against) will have levels
that are too high for your pro gear.  You might get away with just padding
the input and bringing down the gain on the mixer input.
