 Media Vision was the original equipment manufacturer (OEM) of the Logitech SoundMan (also marketed as Pro AudioSpectrum 16 Basic) card, which was compatible with the PAS and could thus use the same drivers.The relevance of the PAS faded quickly as Media Vision was rocked by financial scandal and faded from existence.The 16-bit PAS cards employed a relabeled CODEC chip made by Crystal Semiconductors of Austin, Texas (now part of Cirrus Logic) for digital audio playback and recording and an AdLib-compatible Yamaha OPL3 FM music synthesizer.
