Using the surround back channel
• Default setting: SB CH ON
You can have the amplifier 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.
The remote control menu for this step is shown below
(see note at the start of this chapter if you need help).
Each press changes the setting as follows (see the table
above for an explanation of each):
• 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 ON – 6.1 or 7.1 encoding is always used (for
example, on 5.1 encoded material)
• SB CH OFF – Surround back channel is switched off
Note
• You will only hear the surround back channel when
you’ve selected SPA as the speaker setting (see
Switching the speaker system on page 75). Changing
the speaker system may automatically change this
setting (see notes below).
• If the surround back speaker is set to NO in Speaker
Systems on page 52, or you have selected SPA+B
as the speaker setting, you can only use the virtual
surround back effect (see next page).
• You can’t select the surround back channel setting (it
is automatically switched off) when you’ve selected
SPB as the speaker setting or when Bi-Surround is
selected in Speaker Systems on page 52.
• You can’t use the surround back channel setting
when Stream Direct is on or when the STEREO mode
is selected.
• When the THX mode is selected, you can’t select SB
CH OFF if you’re listening to DVD-Audio or SACD.
