What is the best network topology for live sound?

For live sound reinforcement, the star topology is widely regarded as the best choice. In this setup, each audio device (such as DSPs, amplifiers, and mixing consoles) connects directly to a central network switch. This minimizes cable runs, reduces the risk of a single point of failure taking down the entire system, and simplifies fault isolation. SSOUNDS engineers typically deploy managed switches with redundant power supplies and QoS (Quality of Service) to prioritize audio traffic, ensuring glitch-free performance even in demanding festival or touring environments.

While daisy-chain or ring topologies can reduce cable length, they introduce higher latency and a single cable break can disrupt multiple devices. Star topology, combined with redundant network paths (e.g., using two switches or redundant links), provides the resilience required for critical live events. SSOUNDS systems are designed to integrate seamlessly with standard Ethernet-based audio protocols like Dante, AVB, or AES67, leveraging star topology for optimal clock synchronization and minimal jitter.

For large-scale deployments, a hierarchical star (or tree) topology can be used, where multiple switches connect to a core switch. This scales well for multi-zone venues or distributed PA systems. SSOUNDS recommends using a dedicated audio network separate from control or data networks to avoid congestion. Always use shielded CAT6a or fiber cabling for long runs, and configure IGMP snooping to manage multicast traffic efficiently.
