With a 7.1-channel surround system, audio signals that

Each press cycles through the options as follows:

•

 – Matrix decoding processing for generating 

the surround back component from the surround 

component is turned on.

•

 – Matrix decoding processing for generating 

the surround back component from the surround 

component is switched automatically. Matrix 

decoding processing is only performed when surround 

back channel signals are detected in the input signals.

 – Matrix decoding processing for generating 

the surround back component from the surround 

component is turned off.

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.
