• Choose the correct setting as follows:

Setting	What it sounds like
Correct	The sound between the speakers is very even, and
	does not change radically as you move your head.
Incorrect	The sound appears diffused, and changes in timbre
	and apparent location as you move your head.

Pay particular attention to the centre channel, as this can have a dramatic effect on the overall sound.
