Gain Structure
Also: gain staging
Gain structure (or gain staging) is the discipline of setting signal levels correctly at every stage of the audio path (preamp, console, processing, amplifier) so each stage operates comfortably above its noise floor and safely below clipping.
In practice
Every device has a happy zone; gain structure keeps the signal in it end to end. The classic failures are complementary: too little gain early forces later stages to amplify noise, while too much gain early clips the preamp and no downstream fader can un-distort it.
Live workflows anchor gain at the preamp (set while the source performs at show level), leave faders near unity for resolution, and match console output to amplifier input sensitivity. Digital consoles moved the clipping points but not the concept; the meter ladder still has to make sense from stage to speaker.
How you’ll hear it
"The vocal is clipping the preamp, not the bus; drop the gain 6 and ride the fader up."
