RME Digiface Ravenna 256-Channel USB Audio Interface

$2,099.00

The RME Digiface Ravenna 256-Channel USB Audio Interface is a portable, high-channel-count device designed to bridge the gap between computer audio systems and professional Ravenna and MADI audio networks, offering flexible connectivity and robust performance. 

The RME Digiface Ravenna is a lightweight and portable audio interface developed in collaboration with DirectOut, based on the proven Digiface Dante design. It provides up to 128 channels of Ravenna audio via four RJ45 Ethernet ports and 64 channels of MADI I/O via two BNC coaxial ports, all simultaneously transferable via a single USB 3.0 connection to a computer. This interface supports a full Ravenna stack with compatibility for industry standards like AES67, ST 2110-30/31, and ST 2022-7, ensuring seamless interoperability in broadcast and professional A/V environments.

About the RME Digiface Ravenna 256-Channel USB Audio Interface

RME made the two BNC sockets for word clock I/O switchable to MADI I/O, with up to 64 channels. The total sum of Ravenna and MADI, 128 channels, are transferred via USB 3.0 and handled via the included RAVENNA web server or RME's TotalMix FX, for full and struggle-free control of all audio.

On the network side, the interface features a full-fledged RAVENNA stack with AES67 and ST2110-30/31 support and redundant audio-over-IP streaming as per ST2022-7. In addition, the interface can also be used as a mobile 64-channel RAVENNA/MADI converter without a USB connection to a computer. The coaxial MADI I/O connectors may also be configured to work as word clock sync I/O.
