Using surround back channel
processing
• Default setting:
SB ON
You can have the receiver automatically use 6.1
decoding for 6.1 encoded sources (for
example, Dolby Digital EX or DTS-ES), or you
can choose to always use 6.1 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 origi-
nally encoded (in which case, you can simply
switch surround back processing off).

Using Virtual Surround Back (VSB)
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.
