an amplifier that provides switching and attenuation in a single package
An amplifier containing the pre-amplifier and the power supply in one unit.
An amplifier that includes a decoder and power amp in one case
An amplifier containing two stages: a 'Pre-Amplifier' and a 'Power Amplifier'. Commonly used for domestic hi-fi applications.
Single unit containing both a preamplifier and a power amplifier.
A combination preamp and amplifier.
Sometimes called a control amplifier, this is a receiver minus a tuner or, if you like, a power amplifier plus a preamplifier. Some integrated amplifiers are very elaborate and contain A/V switching and even surround-sound processing.
Audio component combining the elements of an amplifier with those of a preamplifier but not containing a tuner (making an integrated amplifier different from a receiver which does contain a tuner).
Unit combining a preamplifier and power amplifier.
An integrated amplifier is an electronic device containing an audio preamplifier and amplifier in one unit, as opposed to separating the two. Most modern audio amplifiers are integrated and have several inputs for devices such as CD players, DVD players, and auxiliary sources. Integrated amplifiers commonly had dedicated inputs for turntables, AM/FM tuner, and tape recorders (cassette or reel-to-reel) back when those devices were more common.
