ok here is how i set up my kit. my partner uses the beo cable for her ipod and just plugs into the phono cable and she just uses it as is.
all speaker functions are the same as if it was the beogram connected. with the exception of a crappy supressed sound
avant-linked-bc2300-bl8000 at the front.
when i switch on i get speaker 3 which gives me all the speakers from the avant to the bl8000's. i goto-list-speaker 2 and it locks off the avants speakers and just has the bl8000s playing.
to change list-speaker 1- and it locks out the bl800's and just plays the avants speakers.
beo4 -menu-setup-sound-speakers-FRONT SPEAKERS TYPE A and to the right of that is REAR SPEAKERS NO
NOW follow this- beo4-menu-set up-sound-speakers- FRONT SPEAKERS-select and then NONE- GO (TO STORE) and go again then switch off. the default will be just the avant speakers or whatever device you have. this will put the visual system in audio peripheral lock out with the exception of the avant. reverse of procedure to have all working.
i dont think there is a definitive default preference.
i sure hope this helps. if not im sorry but i do think i get the gist of what you are asking.
