Know nothing but want it all!

Once more I return to the fountain of all knowledge - pistonheads!

I have a barn that I have done out for the kids to play in. I am going to put an computer and an overhead projector in. I will get a gizmo that connects the TV aerial to the computer so I can send freeview TV to the projector via the computer, I will fit a sound card to the computer that can give surround sound - where is this going....I am looking for an amplifier that will give surround sound from the computer but also will allow Karaoke and will allow the kids to connect their guitars into etc. Anyone any suggestions, would prefer an amplifier and speaker package if possible?

You will not find an AV amp that does all that. AV amps accept Digital and RCA connectors, Guitars use Jack plugs. You might be able to get a box that converts them but that will be addition to the AMP.
