This article will show you how to configure Zyxel Layer 3 switches such as the GS2220, XS3800, XMG1930, XS1930, XGS2220 and Dante AV System. (Audio Video over IP)

Dante is the evolution of AV systems, converging all previous connection types into one. Dante delivers vastly superior performance while making these systems easier to use, easier to expand, and less expensive to deploy.
