Gain & clipping

Gain structure and what happens at the limit.

Why it matters

Bad gain structure makes a build noisy, weak, or harsh.

Too little gain means the system cannot reach the target level. Too much gain raises noise and makes the volume control touchy. Clipping can add harsh distortion and push extra heat into drivers.

How it works

Every stage has a maximum clean level. The source, DSP, preamp, amplifier input, amplifier output, and power supply all have limits.

When the signal exceeds a limit, the waveform is flattened or distorted. That is clipping. It can happen before the power amp, inside the amplifier, or because the power supply cannot keep up.

Common mistakes

Simple example

Amplifier An amplifier takes a small audio signal and delivers a stronger voltage and current signal to a speaker. The speaker load, power supply, gain, and protection limits decide how hard it can work. Amplifier parameters Amplifier parameters explain what load the amp can drive, how much clean output it can deliver, how much gain it has, and where it clips, heats, or protects itself. Wattage Wattage is electrical power. In audio, it helps describe amplifier output and speaker power handling, but it does not directly tell you loudness or sound quality. Power supplies A power supply turns wall or battery power into the voltage and current an amplifier needs. Its voltage, current limit, noise, and protection affect the whole build.
