gb,

Any analogue audio input (except for the "Multichannel input") should do. Aux 1 or 2 are my choices since they are not labelled as something else (like "CD".) There should be no difference in sound for any of them. Just set-up your surround mode preference for whatever you are most likely to want to use most of the time. (PLIIM-CR is my favourite.)

Regards.
