Skill Profile
System Design & Gain Structuring
"The observable action of designing an audio system and setting gain correctly at every stage to maximise headroom, minimise noise, and ensure the system performs reliably at any volume."
YOUR SKILLS
Problems This Skill Solves
- A PA system is excessively noisy because the gain was set too high at the console and too low at the amplifier.
- A system distorts at moderate volumes because gain was added at multiple stages rather than set correctly at the source.
- A venue's installed sound system sounds poor regardless of what is played through it because the system was never properly calibrated.
- An amplifier clips before it reaches design output because the drive level from the console is insufficient.

"Turning everything up as high as possible gives you the most headroom"
Headroom requires discipline at every stage — overdriving early in the signal chain saturates subsequent stages regardless of how low the output is set.
"Gain structure is mainly about preventing feedback — once feedback is controlled, the gain structure is adequate."
Feedback avoidance is one constraint on gain structure, not its purpose. Gain structure determines signal-to-noise ratio, headroom, and how the system behaves when individual channels are pushed. A system with adequate feedback margin but poor gain structure will exhibit noise floors that compromise intelligibility and clip unpredictably under normal performance conditions.
Research & Outlook
As systems become more complex and digital, system design requires understanding of both analogue principles and networked audio protocols.

Growth Path
How to Practise
- 1.Set the gain structure for a fictional four-stage signal chain from scratch
- 2.Study the relationship between noise floor, dynamic range, and headroom
- 3.Analyse why a system sounds distorted or noisy and trace it to a gain staging error
How to Prove
- ·System commissioned with clean, headroom-appropriate gain structure across all stages
- ·Venue or studio installation that passes commissioning tests first time
