What Are Integrated Amplifiers?
In home stereo systems and home theater sound systems, sound is reproduced by using a preamplifier and a power amplifier. Audio devices that combine the preamplifier and amplifier in one unit are called integrated amplifiers. Separate components are usually best for reproducing music, while integrated amplifiers work well for home theater systems using surround sound. When an integrated amplifier is used, sound is first sent from different audio devices to the preamplifier. It raises the signal level just enough to send it to a power amplifier. The power amplifier raises the sound level enough for people to hear the sound. The sound is then reproduced by the speakers connected to the integrated amplifier. Amplifiers typically include several audio inputs for different devices, such as a television, CD player, DVD player, and a satellite or cable television receiver box. Some also include inputs for tape decks and turntables. Integrated amplifiers also include outputs for speakers. Inte
