Using the Virtual Surround Back mode
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 amplifier only apply this effect
to 6.1 encoded sources like Dolby Digital EX or DTS-ES.
