I own two "Pro Audio 3D" boards, which consist of the "Premium 3D" board combined with the Korg, "Pro Wave" DB. It's a pretty decent card, in my opinion, and I know that Trixter has some nostalgia for it as well.
The Premium 3D, with its Jazz16 chipset, builds upon the PAS-16 line by offering SRS sound-enhancement technology, a "supported" WaveBlaster header, Sound Blaster Pro (2) digital/FM support, a faster SCSI chipset (on the SCSI model), and support for VESA's VBE/AI sound standard initiative.
There are a few pretty big caveats to consider though, in my opinion:
- The Pro/Premium are not backwards-compatible with the PAS/PAS16
- The Pro/Premium are not mixer-level compatible with the Sound Blaster Pro
- There's no 16-bit digital playback in DOS outside of the VESA driver interfacing... which almost no software supports. (Way to go, MV!)
With Media Vision's follow-up product, the "Deluxe," the MVA-508B mixer chip is replaced with the MVA-514, which is less feature-rich, but fully SBPro mixer-level-compatible. SRS is dropped, however. I don't own one of these, inexplicably... 🙁
Were the PAS 16's Full-Duplex cards like the AWE32?
