LX-IP OEM Solution

In addition to offering end-users a fully functioning PCIe interface for RAVENNA streaming the Digigram LX-IP card provides manufacturers with a ready-to-go RAVENNA streaming solution ideal for use on Mixing Consoles and other audio systems that support the PCIe interface.

The LX-IP RAVENNA PCIe sound card, the first RAVENNA-enabled product developed by Digigram, features ultralow latency - down to one audio sample per IP packet - and up to 256 RAVENNA I/O channels from multiple RAVENNA streams. Ideal for high-density audio production or automation applications in radio and TV broadcast studios, this solution makes it easy for users to record and play as many as 128 audio-over-IP RAVENNA channels simultaneously in/out of a desktop computer.

Boasting ultralow, round-trip latency down to 3 ms, interoperability with all AES67 requirements, embedded 128 x 128 switching matrix, Grandmaster PTP clock abilities, and high redundancy assured by two Gigabit Ethernet connections, this reliable hardware solution enables broadcasters to maintain high performance regardless of the computational load presented by other applications running on the host system.
