The Pro Audio Spectrum 16 (pas16) is an obsolete ISA non-Pnp audio card produced by Media Vision, a company that went down in flames after the CEO was discovered cooking the books. That said, I own one and the sound quality is quite nice. And when I wanted to use it (in place of a PoC SBPro; 8bit+22Khz max? feh!) I could not find documentation online about the jumper settings. Hence what follows.
There appears to be more than one board labeled "PAS16" out there. This diagram does not match my board at all, but maybe it matches yours. My board has a much smaller cdrom connector than the 50-pin scsi connector that that site shows, and the silkscreen reads "(c)1993 PRO AUDIO 16 LMSI 650-0082-03-A FCC ID: IXW-LMSI2". My board is a full length 16-bit ISA card, and there is a depopulated 20-pin J2 at the top edge of the board. On top of that some diagrams in my manual are obviously mislabeled.
J3 DRQ/DMA Select The only setting documented is no jumpers (which the manual confusingly indicates by a grey block covering pins 1 and 3, but it is supposed to represent two spare jumpers, one hanging off pin 1 and the other off pin 3. Another part of the manual calls this jumper "Factory testing" so I assume the other settings are not useful to the end user. J4 DRQ Select 1-2 DRQ latching disabled (no shared DMA) 2-3 DRQ latching enabled (shared DMA) (default) J5 CD-ROM Audio In 1 Right Signal 2 Ground 2 Left Signal External connectors, from top to bottom J8 1/8" AUX In J6 1/8" Speaker Out J7 1/8" MIC In J9 Joystick/MIDI Port J17 CD-ROM Data Connector J18 CD-ROM I/O Address Select no jumpers 0x300 5-6 0x310 3-4 0x320 3-4 & 5-6 0x330 1-2 0x340 (default) 1-2 & 5-6 0x350 1-2 & 3-4 0x360 1-2, 3-4 & 5-6 0x370 J19 CD-ROM IRQ Select 5-6 IRQ 11 (default) 3-4 IRQ 12 1-2 IRQ 15
The native sound portion of the PAS16 is based at I/O address 0x388 and uses IRQ 10, DMA 3.
The sound blaster compatability circuitry uses IRQ 5, DMA 1, and is based at 0x220, like the default sound blaster settings.
