Using the surround back channel

• Default setting: SB CH 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 with other sources (for example, 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 the surround back channel off. The table below
indicates when you will hear the surround back channel
when playing various kinds of sources.

• Press SB CH MODE repeatedly to cycle through
the surround back channel options.
Each press changes the setting as follows (see the table
above for an explanation of each):
• SB CH ON – 6.1 or 7.1 encoding is always used (for
example, on 5.1 encoded material)
• SB CH AUTO – Automatically switches to 6.1 or 7.1
decoding for 6.1 encoded sources (for example,
Dolby Digital EX or DTS-ES)
• SB CH OFF – Surround back channel is switched off
Note
• You will only hear the surround back channel when
you've selected Normal Surround in the Surround
back speaker setting on page 55. Changing the
speaker system may automatically change this
setting (see notes below).
• If the surround back speaker is set to NO in Speaker
Setting on page 55, or you have selected a Second
Zone speaker B setup, you can only use the virtual
surround back effect (see next page).
• You can't use the surround back channel setting with
MULTI CH IN or STEREO/DIRECT.
• You can't use the surround back channel feature with
DVD-A, SACD or sources over 48kHz when using one
of the digital inputs (including i.LINK).
