If the … Amplifier headroom is the amount of power that an amplifier is able to generate before it starts overdriving. Overdriving means adding gain to the signal, natural gain coming from either the preamp, or the power amp section, or both. In other words, amplifier headroom is just how loud and clear can an amplifier be naturally.
