What is the best network topology for live sound?
Quick answer
The best network topology for live sound is a star topology using redundant, daisy-chained switches with AES67 or Dante protocol for low latency and reliability.
In live sound, network topology directly impacts audio reliability, latency, and ease of troubleshooting. The star topology is widely preferred because each device connects directly to a central switch, isolating faults and simplifying cable runs. For larger systems, a hybrid approach with multiple star nodes linked via fiber or copper trunks maintains signal integrity over distance.
Redundancy is critical: dual-redundant networks (primary and secondary) using separate switches and cables ensure failover without audio dropouts. SSOUNDS engineers implement this with managed switches supporting IGMP snooping and QoS to prioritize audio packets, minimizing jitter and packet loss even in complex line array deployments.
Protocols like Dante and AES67 are optimized for star topologies, offering sub-millisecond synchronization and easy integration with digital consoles. For permanent installations, a daisy-chain of switches in a star-of-stars configuration provides scalability while keeping each segment manageable. Always use shielded CAT6 or fiber for long runs to prevent electromagnetic interference.
Key things to consider
- Star topology is best for fault isolation and easy troubleshooting in live sound.
- Use dual-redundant networks (primary/secondary) with managed switches for failover.
- Enable IGMP snooping and QoS to prioritize audio traffic and reduce latency.
- Protocols like Dante or AES67 work optimally with star topology for low jitter.
- For large venues, deploy multiple star nodes interconnected via fiber trunks.
