The Iscans also work as a Hub.
picture and sound should go to directly to Iscan and then sound to Arcam and Picture to Projector.
That way you don't need to change channels on the Arcan processor depending on which source you use. The Iscan will trigger the sound depending on which source is turned and send to Arcam.
I have my Iscan feeding a Coaxal Digital into the "TV" label of my H/C Amp.
I also have my xbox direct into my H/C Amps "TV" labelled Optical input so again no need to change the amp input wheather I be using DVD, Freeview or Xbox.
When I use TV, whatever the source I just need the amp on TV
