Audio Amplifiers

Audio Amplifiers are used to make sound louder and crisper. An integrated amp is like a receiver without the AM/FM tuner. A basic integrated amplifier combines a two-channel or multichannel amp with a pre-amplifier (also known as a control amp) for selecting audio components and operating tone controls. Integrated amplifiers are often accompanied by a separate AM/FM tuner.

Audio Amplifiers can be found online or in stores. A pre-amplifier is also known as a control amplifier because it’s where all components are connected and controlled. A pre-amp provides a small amount of amplification, only enough to send the signal to the power amplifier, which amplifies the signal enough to power speakers.

A power amplifier provides the electrical current to drive loudspeakers and they are available in two-channel or several multichannel configurations. Power amps are the last component in the audio chain before the loudspeakers and should be matched with the capabilities of the speakers. In general, the power output of the amp should be closely matched with the power handling capabilities of the speakers.
