RME Digiface Ravenna – 256-Channel 192 kHz USB Audio Interface RME

The Digiface Ravenna is a lightweight, portable audio interface, based on the proven Digiface Dante equipped with a RAVENNA module developed by DirectOut and features with everything that RME is famous for: USB 3, MADI, TotalMix FX and outstanding options in both USB and stand-alone operation.

Mobile RAVENNA Solution via USB

The combination of RME’s renowned drivers (Mac/Windows) and DirectOut’s RAVENNA implementation offer a reliable and flexible networked computer audio interface. Equipped with the latest TotalMix FX it can not only route, but also mix as many independent submixes as outputs are available. The included high quality phones output offers a quick listen to any audio channel, but can also be used as line output to provide an additional analog stereo mixdown.

RAVENNA & MADI

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.

TotalMix FX and TotalMix Remote

Like all the latest RME interfaces, the Digiface Series also includes the powerful digital real-time mixer TotalMix FX. It allows for practically unlimited mixing and routing operations, with all inputs and playback channels simultaneously, to any hardware outputs.

The Digiface Series includes a dedicated Control Room section with Talkback, Main/Phones, fader groups, mute groups, complete remote controllability via Mackie or OSC protocol, and much more. The Digiface Series does not support DSP based effects (FX) like EQ or reverb.

Additionally RME’s latest software, TotalMix Remote, enhances the power of RME interfaces by enabling remote control via iOS, PC or Mac. With a straightforward set up process — simply enter the IP address of the computer you would like to control with TotalMix Remote and get going — users can quickly adjust any aspect of TotalMix FX on a host system while walking around the studio with their tablet, or from a control room located elsewhere in the facility.
