Digigram ALP-AES67 Ravenna AES67 SMPTE ST-2110 PCIe Sound Card

Part of the ALP-X professional sound card range, the Digigram ALP-AES67 is a multichannel PCIe sound card with four Ethernet ports that work with AES-67, SMPTE ST-2110, or Ravenna protocols for (up to 64x64 I/O) large-scale audio applications. The card operates under Windows and Linux environments and guarantees submillisecond round-trip latency and seamlessly integrates with AoIP networks.

Used with ALP-X Manager, Digigram's unified control panel for the whole ALP range, ALP-AES67 works with applications where critical audio is paramount, including broadcast, public safety, medical, and transportation.
