Admos A411-G70 PCI Sound Card Xwave QS3000A CD Audio Game Port DOS

Admos A411-G70 PCI Sound Card Xwave QS3000A CD Audio Game Port DOS

The Admos A411-G70 is a PCI sound card built around the Admos QS3000A audio controller chipset, marketed under the Xwave brand. It provides stereo audio output, microphone input, and line-in capability via three 3.5mm jacks on the bracket, along with a 15-pin DB-15 MIDI and game port. An internal CD audio header and a PC speaker header are also present on the board, making it a straightforward drop-in audio solution for late-1990s and early-2000s desktop PCs.

Applications

PCI sound cards like the Admos A411-G70 were designed for desktop PCs in the late 1990s through early 2000s, when integrated motherboard audio was uncommon or absent. Cards of this type are compatible with Windows 95, 98, ME, and DOS environments, and are sought today primarily for retro/vintage PC builds — particularly DOS gaming rigs and Windows 9x era machines where period-correct audio hardware is desired. The QS3000A chipset supports standard DirectSound and legacy audio APIs used by games of that era. The onboard game port doubles as a MIDI interface for connecting joysticks or external MIDI devices, and the CD audio header allows direct analog audio passthrough from an optical drive.
