Using off-the-shelf routing equipment to send audio over IP in small to medium-sized systems offers cost advantages over synchronous solutions using AES-10 (MADI) or TDM buses. These have higher capacity, but require powerful hardware. Besides, large TDM systems can reduce their cost and at the same time increase their flexibility when they are combined with IP audio links to connect a few circuits with a central router. That’ s why when developing the AEQ IP audio routing system, we have not only created routers with AoIP connection and IP connection elements for the consoles, but also the following interfaces or patch panels that allow audio inputs and outputs to be installed where it is necessary.
