This will simulate various lighting conditions. Press X and that player is active. Move him to a position for receiving the throw-in. Now press the square button and the ball will be thrown to the player. Obviously, change Dolby to On from the options menu.
Most dialog uses the center channel.
The sound also is pretty damn good with Dolby off, fed through a stereo TV or audio system. Although the manual doesn't mention this, you need to hold down the X button, while selecting a direction, then release the X button to pass. The longer you hold down X, the stronger the pass will be. If your lob passes just bloop into the air, as mine did, then this is the problem. However, you can be pressing the direction buttons while you wait for the shooter, then hit the action button.
