Are SuperMAC and HyperMAC networks?
SuperMAC and HyperMAC are both more of a point-to-point connection than an audio network. In some ways, they could be considered as successors to MADI. Routing is centralised, not distributed, giving better latency control, better reliability and finer routing granularity than distributed audio networks. However, the Ethernet-compatible auxiliary data (general-purpose data for control, metadata, etc.) does function as a true, packet-switched network, giving you the best of both worlds: tightly-controlled audio flow, with very flexible control data routing.
A dedicated SuperMAC and HyperMAC Router, such as the Midas DL461 Audio System Signal Router provides channel-by-channel audio routing (like a patch bay), as well as packet switching for the auxiliary data messages. This provides robust, low-latency and deterministic latency audio routing, with the benefits of a true packet-switched network for the control data.
