I'm back home and following your advice does not seem to give a result right away.
I can see now that I was wrong to say the red/white pair of sockets I was using to come out of the ION were labelled "phono out." They in fact say "LINE OUT."
So should I still be using them to head towards the amp on my SONY. There are no other sockets, other than a similar pair saying " LINE IN," (which I believe are for recording from an external source onto the internal flash memory in the ION.)
(There is also a USB exit and a USB cable, which I believe is for having the ION talk to a PC and put music in ITunes.)
Then when I look at the back of my SONY, there are:......
a pair labelled PHONO IN,
two pairs IN and OUT in a section labelled MD
a pair AUDIO IN and AUDIO OUT, and a single (white) VIDEO IN in a section labelled VIDEO, and finally a single (white) VIDEO OUT.
( There is no USB female socket and there is no jack socket.)
Please tell me what I should connect to what to hear a vinyl record playing on the ION over the speakers attached to my SONY.
