NETWORK ATTACHED DIGITAL TO ANALOG CONVERTER
Nice acronym, but what is it all about? The modern world has become dependent on networks and the technology has been designed to be reliable and scalable. As the network capacities have increased, the possibility of using IP networks for video and audio became an obvious choice. Clearly Gigabit Ethernet had sufficient capacity for high quality audio but it was not optimal without an additional protocol adding the required precision and management. Merging needed to move away from the PCIe technology that had served us well for many years and we looked at alternatives that could offer sufficient accuracy and reliability with high channel counts and Hi-Res Audio data rates. Other IT based point-to point connections such as USB or Firewire were either not optimum or obsolete for audio even though other manufacturers had pressed them into service. There was only one choice that made sense: RAVENNA.
