MULTI-CHANNEL LOW PROFILE
PCIe SOUND CARD

ALP882e

Universally acclaimed, unchanged Digigram features are still up to meet your challenges. Your favorite 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.

ALP882e is a versatile multichannel PCIe sound card for professional PC-based audio systems running under Windows and Linux environments. With its reliability, stability and compact low profile design, ALP882e is ideally suited for mission-critical applications in the broadcast, industrial, and military markets. This card is ready for any challenge. It offers eight balanced analog line inputs plus four stereo AES3 inputs, eight balanced analog outputs plus four AES3 output, and 8 GPIs / 8 GPOs.

The on-board zero latency mixer features 32 I/O channels (8 analog, 8 AES3, 16 software play/record). Each of the 32 output channels has its own mix from the 32 inputs.

Q&A

Sound cards

Which Linux Distribution are supported for sound cards ?

LoLa soundcards and multichannels VX/PCX series are supported on every Linux distribution, as the ALSA driver is part of the kernel.

The VX and PCX stereo cards have precompiled versions for Debian, Ubuntu, CentOs, Fedora, and OpenSuse-based distributions. For the LX series, the following distributions are supported: Ubuntu LTS / Debian LTS / CentOS 7.

For other Linux distributions, we propose a service for providing an adequate compiled and installable driver package. UAX and Cancun series will work on every Linux distribution.

My sound card is not detected by Windows

Make sure that you downloaded the lasted driver on our website. Indeed, from time to time we have to make component updates that require a new driver.
