Dolby Pro Logic IIx
Mode Group
An expansion of Dolby Pro Logic II that adds a surround back channel which may
be played through one or two surround back speakers. The Dolby Pro Logic IIx
modes may be selected not only with Dolby Digital bitstreams, but thanks to the
AVR’s post-processor, they may also be used with some DTS bitstreams to add a
surround back channel to 5.1 modes.
