AMPLIFIERS - INTEGRATED, PRE & POWER
An Amplifier is so much more than just a box that makes your speakers loud; different designs affect the tonal balance of everything you hear.
An Integrated Amplifier is a Pre-Amplifier and a Power Amplifier combined. A Pre Amplifier is perhaps best explained as a mixer or control box, it directs the music signal through the controls and allows switching to different outputs, it cannot drive loudspeakers. A Power Amplifier is the output stage with the ability to drive speakers, using two Power Amplifiers to Bi-Amp a system is regarded as the route to ultimate quality.
A Stereo Amplifier has two channels of sound, an AV Amplifier or Home Cinema Amplifier both offer 5.1 (or 6.1 / 7.1) outputs and are used to drive a Home Cinema system with at least 5 channels of sound for the front, centre and rear speakers plus a dedicated Subwoofer output. A Home Cinema Amplifier or AV Amplifier can normally be used for Stereo playback as well.
A Phono Pre Amplifier
