I keep seeing Aztech cards of the same appearance being called different names all over the web, so honestly, I feel very unsure which model is which and I somehow doubt that anyone who doesn't have a boxed model actually knows for sure. But sure, it may well be called "Pro 16", I personally have no clue. I wish I could find a complete list, with pictures, of all Aztech sound cards, because I do feel a bit of nostalgia towards them. Mine came in a multimedia kit together with a 4x CD-ROM drive and a set of crap speakers.
