Using surround back channel processing
You can have the receiver automatically use 6.1 or 7.1
decoding for 6.1 encoded sources (for example, Dolby Digital
EX or DTS-ES), or you can choose to always use 6.1 or 7.1
decoding (for example, with 5.1 encoded material). With 5.1
encoded sources, a surround back channel will be
generated, but the material may sound better in the 5.1
format for which it was originally encoded (in which case, you
can simply switch surround back channel processing off).
• 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 , then press SB CH repeatedly to cycle
the surround back channel options.
Each press cycles through the options as follows:
• SB ON – Matrix decoding processing for generating the
surround back component from the surround component
is turned on.
• SB 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 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.
• Using the Up Mix function is effective when the speakers
in the 7.1-channel surround system are set up as
recommended in the example on page 10.
• Depending on the positions of the speakers and the
sound source, in some cases it may not be possible to
achieve good results. In this case, set the setting to
OFF.
1 Switch the receiver into standby.
2 While holding down PRESET  on the front panel, and
hold the  STANDBY/ON for about two seconds.
UP MIX: OFF appears and the Up Mix function turns off. If
you want to turn this function on, perform steps 1 and 2
again.
• When set to ON, the (Up Mix) indicator on the front
panel lights.
Note
• Set to ON regardless of this setting when playing DTS-HD
signals.
• May automatically be set to OFF even when set to ON,
depending on the input signal and listening mode.

make using the
AUDIO PARAMETER menu. The defaults, if
