You will also need to go in the menu of your TV and change the sound settings.
You need to tell the TV that the Beolab 8000 are connected.
You need to do the surround setting and indicate the distance between yourself and the various speakers.
You can set the default speaker configuration when using the audio source, and when using the video source. You can always override this configuration when listening or viewing something by using the SPEAKER softkey on the Beo4.
You should not have to use the AV key any longer.
The TV will turn itself off if you start an audio source. and vice versa.
When listening to TV program that have dolby information or DVD, you will here different sound in the 3 speakers.
If you have some Timer programming, like to wake you up in the morning, remove them from the Beosound and enter them in the TV.
I hope your Beolab are on each side of your TV. You'll love your new setup.
