Gain Staging in Mixing: Level Management

Gain staging manages signal levels throughout the mixing chain. Proper levels ensure plugins operate optimally, prevent clipping, and maintain headroom for the mastering stage. Understanding gain staging produces cleaner, more professional mixes.

Why Gain Staging Matters

Signal level affects how processors behave. Plugins modeled on analog gear expect specific input levels. Too hot or too cold input may cause unexpected behavior.

Cumulative gain changes accumulate through the signal chain. Each plugin’s output feeds the next plugin’s input. Without attention to staging, levels can grow problematically or diminish unnecessarily.

Master bus headroom depends on individual track levels. High levels throughout the mix leave no room at the master. Appropriate staging preserves headroom for final processing.

Optimal Operating Levels

Modern digital mixing often targets -18 dBFS as a reference point. This level corresponds roughly to 0 VU on analog meters. Many plugin models expect signal around this level.

Peak levels shouldn’t hit 0 dBFS on individual tracks. Leaving headroom—typically peaks around -6 to -12 dBFS—provides safety margin and proper plugin operation.

The mix bus should have significant headroom before hitting 0 dBFS. Targeting peaks around -3 to -6 dBFS leaves room for mastering processing.

Input Gain Management

Starting with appropriate levels sets the foundation. Adjusting clip gain or input trim before processing establishes proper operating level.

Normalizing to a target level—like -18 dBFS average—creates consistent starting points across tracks. This consistency makes subsequent processing more predictable.

Hot recordings may need attenuation before processing. Pulling levels down to appropriate range ensures plugins work as intended.

Managing Level Through Processing

Each processor’s output should approximately match its input. If a compressor reduces gain, makeup gain compensates. This maintains consistent flow through the chain.

Watching levels after each plugin reveals accumulation. If levels grow significantly through the chain, adjustments at individual stages correct the flow.

Bouncing or committing processed signals at appropriate levels locks in proper staging. Rendered files carry their levels forward.

Bus and Master Considerations

Group buses summing multiple tracks need appropriate levels. Many tracks combining can create hot bus levels. Trim controls on tracks feeding buses manage this.

Master bus processing operates best with headroom available. Squeezing every dB from the mix before mastering limits mastering options.

Metering at various points—individual tracks, buses, master—reveals where levels need attention.

Common Problems

Clipping at any stage degrades quality. Digital clipping creates harsh distortion. Watching meters throughout prevents this.

Excessive level reduction creates noise issues as signal approaches the noise floor. Maintaining healthy levels keeps signal above noise.

Inconsistent levels across tracks make balancing difficult. Standardizing operating levels simplifies mixing decisions.
