Digigram ALP222e-MIC

Universally acclaimed, unchanged Digigram features are still up to meet your challenges. Your favourite, trusted PCX and VX cards essentials still fuel the new Digigram ALP-X range.

Same quality, same high standards. A new technology core for this new cards range will push back the limits, offer enhanced performances and simplify users’ daily routines with ALP-X sound cards.

ALP222e-MIC 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 multi-card (up to 8 ALP cards) and multi-client.
