Digigram ALP222e Overview

The Digigram ALP222e is a low-profile PCIe stereo sound card engineered for continuous 24/7/365 operation in professional PC-based audio systems. Designed for reliability in mission-critical environments, it supports both Windows and Linux platforms and delivers analog and digital audio connectivity with renowned Digigram sound quality. Its compact form factor fits easily into workstations, servers, or industrial PCs, making it suitable for broadcast, production, transportation, public safety, and utility applications.

Built for Continuous Professional Operation
The ALP222e combines stable low-latency drivers with multicard and multiclient support, allowing up to eight ALP-series cards to operate in the same system. An onboard 8x8 channel mixer provides zero-latency routing and mixing between physical and software inputs and outputs, giving integrators and system designers flexible signal management. With analog and AES3 digital I/O, inter-board synchronization, and a headphone output, the card adapts to a wide range of installation and custom-integration scenarios.
Flexible Integration and Control
Designed for both standard and custom applications, the ALP222e includes a connector for a breakout cable or custom wiring, plus support for Digigram's control API. It offers stereo AES3 digital I/O alongside balanced analog channels, synchronization options including AES11, wordclock, and GPIO connections for external control. A low-profile design with two brackets ensures compatibility with a wide range of chassis types.
