ALP-DANTE- LE PCIe SOUND CARD
ALP-DANTE-LE
ALP-DANTE-LE concentrates Digigram’s expertise, a lighter version of the ALP-DANTE PCIe sound card that benefits from its most prominent features.
This new audio interface has just the right features you need, no more and no less: versatility, reliability, untouched audio quality, plus cost-effectiveness. ALP-DANTE-LE comes with adjusted connectivity, while keeping the same number of channels. This optimized card will power a larger array of 365/24/7 run applications that require recording, playout or real time processing.
ALP-DANTE-LE uses the same sturdy hardware platform as the rest of the ALP-X range, whose proven design is a synonym for legendary reliability. The card also features the famous low-profile form factor, coupled to a fanless design to address audio applications where space and reliability are at stake. ALP-DANTE-LE operates under Windows and Linux drivers and is compatible with AES67 and SMPTE 2110-30 protocols, increasing its versatility to address countless applications regardless of the environments. Lastly, the card seamlessly integrates Dante networks thanks to the usual Dante Controller interface, and Digigram’s signature reliability and low latency coupled with the audio quality inherent in the Dante protocol.
