What is a Stage Box?

A stage box is a box of connectors on stage where microphones and instruments plug in, sending all their signals to the mixing desk through a multicore cable (or snake) or a digital network link. It saves running dozens of separate cables from the stage to front of house, and makes it quick to connect and disconnect each act.

How a stage box works

The stage box sits at the centre of the stage audio system:

  1. Place: the stage box is positioned on stage, often with smaller sub-boxes near the drums and other areas.
  2. Patch: each mic and DI box is plugged into a numbered input, following the patch list.
  3. Send: signals travel to the desk over a multicore or a single network or fibre cable.
  4. Return: outputs for monitors and the PA come back through the same box.
  5. Check: a line check confirms every channel arrives at the desk.

Matching an act's input list to a venue's stage boxes is a key part of advancing in Crescat.

Analogue multicore vs digital stage box

An analogue multicore is a thick cable with a separate pair of wires for every channel. A digital stage box converts the signals to digital on stage and sends them over a single network or fibre cable, which is lighter and carries more channels. Most new installations are digital.

What a stage box usually has

  • Numbered XLR inputs for mics and DIs
  • Outputs for monitors and returns
  • Mic preamps, on digital stage boxes
  • Network or fibre connections to the desk
  • Power and status lights
  • Labelling that matches the patch list

Frequently asked questions

What is a sub-snake?

A small multicore that collects several inputs, such as the drum mics, and plugs into the main stage box. It keeps cables tidy and speeds up changeovers.

Can a touring band use the venue's stage box?

Often, yes. Touring acts with their own desk may bring their own stage box and connect it to the venue system, which should be agreed in the advance.

Why is the patch order important?

If inputs are plugged into the wrong channels, the engineer's mix will be wrong. A clear patch list and good labelling prevent mistakes.
