I'm about to add an Infocus 4805 projector to my home theatre system which currently has a plasma display. The plasma is fed from the single component output from my Denon 3803 amp which has component input from my Denon 2900 DVD player and S video from my Sky + box. The 3803 handles the upconversion and source switching which works very well. The plasma will be used most of the time but a 6ft. wide screen will come down in front to use the projector on 'blockbuster movie nights'. As both the plasma and projector will need to display SDTV and DVD (not at the same time!) I need to split or switch the component output from the amp to either display in turn without degrading the signal. Ideas on how to do this would be very much appreciated as it would be very unsatisfactory to keep pulling plugs in and out. I see that Keene do a 4 input 2 output component switchbox which might do the trick but I'm not sure if this will reduce signal quality. Is there a simple device that will split one signal into two equal ones or even a manual switch?
