Hi There
Just bought a used AV9000 and used many hours last week programming Crestron, testing + + +. I only use ir from Crestron, not the B&Oadapter. (learning a beo- remote takes time since there are a lot of different codes for every button)
Analog TV-channels are soon gone here in Norway so i'm using sat ( non B&O ). Controling the receiver and B&O works just fine. I didn't by speakers ( yet ) so i'm using a pair of sony amps to drive 4 "normal" speakers + sub. Signal that usually turns Beolab's on now goes to Crestron so Sonyamps turns on and selects right input even if I only use the beolink remote when listening to music + + +.
Crestron can do almost everything with B&O but i think its a waste of time programming every possible function so i only have buttons for everyday use like vol,play,stop and selecting sources on touchpanel. I use beolink for advanced operations.
Selecting the right soundmode ( pressing sound + 2 =stereo, sound + 5=surround ) and many other functions can be made easyer with crestron. I made a sound/picture-menu with buttons for mono, stereo, 3D + + + and programmed in the button-sequenses in crestron. In the same menu is level for subwoofer, picture , tone-controls + + + ( and later option for choose between projector and TV. Of course screen wil be hidden, motorized and controlled by Crestron ).
A TV in an other room gets signal from the same sat-receiver and since the touchpanel is wireless changing channels + + can be done easy from the whole house. I don't have but a set of speakers outside can alsow get signal from same system and controlled from Crestron.
AV9000 is an old system compared to the ones you ask about but using them is very similar so if you think you need Crestron, try it!
Good luck, Moritz
