• With a 7.1-channel surround system, audio
signals that have undergone matrix
decoding processing through surround
back channel processing to which the Up
Mix function is added are output from the
surround back speakers.
• Press RECEIVER, then press SB CH
repeatedly to cycle the surround back
channel options.
Each press cycles through the options as
follows:
• SB CH ON – Matrix decoding processing for
generating the surround back component
from the surround component is turned on.
• SB CH AUTO – 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.
• SB CH OFF – Matrix decoding processing
for generating the surround back
component from the surround component
is turned off.
Setting the Up Mix function
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.
