Beskrivelse
ALP222e
ALP222e is a low profile PCIe stereo sound card designed for operating in continuous 24/7/365 use-environments, as part of professional audio applications based on Windows or Linux operating systems.
The card offers analog and digital audio connectivity, and features an on-board 8×8-channel mixer that allows for the routing and mixing inputs to the outputs.
The low latency drivers are multicard (up to 8 ALP cards) and multi-client.
