– Listening in Auto level control mode (page 61).
•
DIRECT
– Sources are heard according to the
settings made in the Surround Setup (speaker
setting, channel level, speaker distance, acoustic
calibration EQ, and X-curve), as well as with dual
mono, the input attenuator, and any sound delay and
hi-bit/hi-sampling
(SC-25 only)
settings. You will hear
sources according to the number of channels in the
signal.
•
PURE DIRECT
– Analog sources are heard without
any digital processing.

No sound is output from the
Speaker B in this mode.

Using surround back channel
processing
• Default setting:
SBch ON
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.

Set the remote control to the receiver operation
mode.

Press SBch repeatedly to cycle the surround back
channel options.
Each press cycles through the options as follows:
•
SBch ON
– Matrix decoding processing for
generating the surround back component from the
surround component is turned on.
•
SBch 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.
•
SBch OFF
– Matrix decoding processing for
generating the surround back component from the
surround component is turned off.
Using the Virtual Surround Back mode
• Default setting:
OFF
When you’re not using surround back speakers,
selecting this mode allows you to hear a virtual surround
back channel through your surround speakers. You can
choose to listen to sources with no surround back
channel information, or if the material sounds better in
the format (for example, 5.1) for which it was originally
encoded, you can have the receiver only apply this effect
to 6.1 encoded sources like Dolby Digital EX or DTS-ES.

•
Press SBch repeatedly to cycle the virtual surround
back channel options.
Each press cycles through the options as follows:
•
VirtualSB ON
– Virtual Surround Back is always used
(for example, on 5.1 encoded material)
•
VirtualSB AUTO
– Virtual Surround Back is
automatically applied to 6.1 encoded sources (for
example, Dolby Digital EX or DTS-ES)
•
VirtualSB OFF
– Virtual Surround Back mode is
switched off
Note
1 There are cases where a brief noise is heard before playback of sources other than PCM. Please select

if this
is a problem.
