Digigram ALP-AES67

The Digigram ALP-AES67  is the newest addition to the ALP-X range of audio interface and redefines versatility and opens new possibilities: ALP-AES67 works with SMPTE ST-2110 and Ravenna for an enlarged scope of applications where audio is at stake. It features a low-profile form-factor that accommodates most PCs and servers. ALP-AES67 also features a fanless design to save on consumption and increase sustainability.

The card’s connectivity, combined with 64 channels of playback and 64 recording channels to/from an AES-67, Ravenna or SMPTE ST-2110 network, opens new possibilities to work under a larger range of audio protocols and deploy broader networks.

Now a classic with Digigram audio interfaces, ALP-AES67 operates under Windows or Linux environments. Built on the same reliable, robust and stable architecture as all ALP cards, ALP-AES67 guarantees sub-millisecond round trip latency and seamlessly integrates AoIP networks.  Used with ALP-X Manager, Digigram’s unified control panel for the whole ALP range, ALP-AES67 works wonders with applications where critical audio is paramount :  in broadcast, public safety, medical, and transportation.
