About RAVENNA
RAVENNA is the name of the protocol that manages the data transfer between the NADAC and a
computer or other hardware when the Ethernet interface is used. This open and published IP network
technology had been created to meet the demands of national broadcasters and focused on the essential
requirements of extremely accurate clocking, high resistance to packet loss and very low latency i.e. getting
the data to where it needs to be, intact and at the right time.
Initially it did not encompass high PCM sampling rates and certainly not DSD. However, it was not difficult to
make changes to allow that, so Merging Technologies worked closely with the developers to make sure that
sufficient channels for the requirements of our professional equipment, with the very high data rate required
by DSD256, could be handled with an accuracy that exceeded anything previously available. It remains the
only logical choice for the professional and the audiophile and is now available in the NADAC. The
added bonus to using an advanced networking solution is being able to send and receive control information
as well as audio data. This opened up exciting possibilities in the studio and now you can enjoy these same
benefits in your own home, as in a networked system using multiple NADACs, the remote control
command data, as well as the audio data are passed to the units via the network.
COMPATIBILITY
The RAVENNA protocol comes with absolutely standard drivers for any computer operating system. ASIO for
Windows, Core Audio with DoP support for MacOS and ALSA for Linux. As easily installed and configured as
any other driver for USB or Firewire, the NADAC RAVENNA driver allows use of any application of
your choice to playback your music files, Emotion, Roon, JRiver, Audirvana, iTunes, etc., as well as any music
server or streamer able to communicate through those standard ASIO or Core Audio drivers.
Using RAVENNA IP audio, the NADAC can connect to a standard network, using off the shelf Gigabit
switches and other IT technology to become a node on a LAN. From that point, any other RAVENNA node can
receive information from and deliver information to, any combination of RAVENNA devices on the network.
