Perhaps this is in my owner's manual, but I can't find mine...

When I listen to CDs, I use my DVD player and I listen in 2-channel, through my mains.
As such, I want the mains set to "Large" and the sub off.

When I watch movies, I set the 1050 to DVD and the mains to 'small', with the sub "on".

My question - how do I assure that my "CD" settings have the mains as large and the sub off, and that my "DVD" setting has the mains set to small and the sub on? It seems like I have to switch it every time I want to watch a movie or listen to music.

Thanks
