An integrated amplifier is a device that combines two essential components of an audio system: a preamplifier and a power amplifier. It is designed to amplify low-level audio signals from various sources, such as turntables, CD players, or streaming devices, and provide sufficient power to drive speakers. Integrated amplifiers offer a compact and convenient solution by integrating these functions into a single unit, reducing the need for multiple components and simplifying the setup. They often include additional features such as tone controls, headphone outputs, and multiple inputs. Integrated amplifiers are commonly used in home audio systems and provide a versatile and efficient solution for amplifying and controlling audio signals with a single unit.
