Morphology
The meaning is directly and transparently derived from combining 'audio' (sound) with 'amplifier' (a device that increases signal strength): it literally denotes a device that amplifies sound. This noun–noun compounding is a regular, compositional pattern that is cross-linguistically common, so a B1 learner who knows both constituents will readily infer the meaning.
Etymology
Audio amplifier combines audio ('sound') and amplifier ('something that makes a sound louder'). Think of it as a megaphone for electronic sound: it makes quiet sound signals stronger so speakers can play them louder.
