In a 7.1-channel surround system with 
surround speakers placed directly at the sides 
of the listening position, the surround sound of 
5.1-channel sources is heard from the side. The 
Up Mix function mixes the sound of the 
surround speakers with the surround back 
speakers so that the surround sound is heard 
from diagonally to the rear as it should be.
