"What is an Audio/Video amplifier?A Home Cinema amplifier is a multi-channel amplifier possessing a decoding processor as well as audio and video connections. This multi-channel amplifier is capable of amplifying more than a simple pair of stereo speakers, having in fact five separate amplification channels (instead of two for a normal stereo amplifier), allowing it to feed, as well as a pair of main speakers, to a central speaker and a rear pair of speakers.
It also possesses an audio processor, allowing it to decode one or several formats of coding for the general public, such as Dolby Surround, Dolby Digital or DTS. It can also carry a THX label, improving its performance even more. A Home Cinema amplifier is also called an Audio/Video amplifier, because it possesses the full range of audio connections, which is normal, but also all video connections. The latter makes this unit very practical, allowing your amplifier to bring together all the audio and video connections of all your hi-fi and video units, becoming a kind of "orchestra conductor" for your installation. This is all the more useful as televisions often don’t harbour enough connections to be able to hook-up all the apparatus you would like, obliging you sometimes to get into some rather "experimental" set-ups, or having to connect each machine in turn as it is needed.
