AV receivers or audio-video receivers are one of the many consumer electronics components typically found within a home theatre system. Their primary purpose is to amplify sound from a multitude of possible audio sources as well as route video signals to the user’s TV from various sources. The user may program and configure a unit to take inputs from devices such as DVD players, VCRs etc. and easily select for which source he or she wants to route to their TV and have sound output.
