What is an audio snake?

An audio snake (multicore) is a bundle of individually shielded audio cables in a single outer jacket, with a stage box at one end and a fan-out of connectors at the other. It carries multiple audio channels between the stage and the mixing desk, replacing many individual cables.

How long should my audio snake be?

Measure the actual route the snake will take — not the straight-line distance. Add 5-10 metres for slack, routing around obstacles, and connecting to stage box and desk. Common lengths: small venue 15-20m, medium venue 30-50m, large venue 50-100m.

What is the difference between sends and returns?

Sends carry signals from the stage to the mixing desk (microphones, DI boxes). Returns carry signals from the desk back to the stage (monitor mixes, effects). A 16×4 snake has 16 sends and 4 returns.

Should I consider a digital snake instead?

Digital snakes (using Cat5e/Cat6, fibre optic, or Dante/AES50) offer major advantages for long runs: no signal degradation over distance, lighter weight, fewer cables, and easy channel expansion. They are increasingly common even in small-medium setups. The trade-off is higher initial cost and need for digital infrastructure.
