Being new to the AV scene I must admit I am a little lost when it comes to inputs and what they do. Analogue is what I'm used to - connecting CD players etc. S - Video ? Purely for vision, can sound run through this? What components usually use this? Optical ? Purely for sound? Does a digital output on a DVD player provide better sound than using all the outputs on a DVD player to amp, or is the differenc negligible. CoAX ?? Again purely sound? Better than digital or a subjective test? SCART Vision and sound? But can it carry 5.1 what would be a usual usage of this. Would the scart from ur dvd player run directly for the TV, whilst all the sound outputs go to the amp? Analogue video - like what is used out of camcorders. A low level? Generally do u connect the sound output of your DVD player to the AMP, and the vision to the TV. So there is no sound going to the TV?? I basically am trying to find out how many and what inputs I should look out for when buying an amp, and am trying to gain a better understanding.
