Specifications

Catalog subcategoryISA legacy sound cards
Product IDMedia Vision Pro AudioSpectrum 16; commonly identified as PAS-16 / 650-series ISA assembly
Bus / host16-bit ISA expansion bus; DOS resource settings and Windows driver version must match the card revision.
Connectors and I/OLine-level stereo out, stereo line-in, microphone input, game/MIDI port, internal audio headers, plus optional onboard CD-ROM interface on some PAS-16 revisions. Verify the rear bracket and actual interface chips.
Chipset / conversion / protocol16-bit stereo playback and recording, with support documented up to 44.1 kHz. PAS-16 audio controller/mixer design includes MVD101 and MVA-508B family markings on documented revisions, plus OPL3-compatible FM; exact component population is board-specific.
Drivers / operating systemsManufacturer software targeted DOS and Windows 3.x/9x-era hosts. Use a PAS-16-specific driver and configuration utility; modern OS support is not claimed.
Variant compatibilityPAS-16 revisions (including different 650-series assemblies) can vary in CD-ROM interface and board layout. Do not assume Media Vision Pro AudioSpectrum 8, PAS+, or other PAS models share the same driver/resource setup.

Service & preservation

Photograph the full board ID, chip labels, jumpers, and CD-ROM connector before cleaning. Preserve original installation media and note I/O, IRQ, DMA, and CD interface. Inspect ISA contacts and electrolytics; do not connect undocumented internal CD pinouts.

Identification and compatibility checks

  • Photograph the product/model label, board silkscreen/revision, connector faces, cable assemblies, and accessory part numbers before installation.
  • Check electrical bus and host slot or USB/MIDI protocol support against the exact manual; connector shape alone does not establish compatibility.
  • For analog I/O, confirm line/mic/instrument level, phantom-power behavior, channel map, and direction from the model-specific documentation before connecting equipment.
  • When software or driver support is uncertain, preserve the last known-good installer and document tested host OS, driver version, and device identifier.
