Optimizing gain at every stage improves mix clarity and headroom
Gain staging means setting a sensible signal level at each point in the chain — multitrack returns, effects sends and returns, external units, and the master recorder — so each stage runs hot enough for a good signal-to-noise ratio but never so hot that peaks overload. Sound On Sound presents this as a simple measure that significantly improves the clarity of a mix: drive the master recorder as hard as possible without clipping the peaks, and keep the intermediate stages optimised rather than letting some run too quiet (noisy) or too hot (distorted). It is foundational housekeeping done before creative mixing begins.
Examples
Before mixing, check each channel’s return level, then the send/return levels for reverbs and delays, then the master bus meter — nudge the master so peaks approach but never hit the ceiling. A track set 15 dB too low forces later stages to add gain and noise.
Assessment
Explain what problems arise when one stage of a signal chain runs too quiet versus too hot, and describe how you would set the master recorder level for maximum clarity without overloading.
