If the AC-3 down-mixing option is installed (available as an option) then
the page shown in Table C.21 is displayed. If the AC-3 decoder is
presented with an elementary stream with more than two channels, the
decoder down-mixes them to produce a stereo pair. The AC-3 Standard
allows for downmixing to a Dolby Pro Logic compatible stereo signal
(designated LT RT) or a conventional stereo signal (designated LO RO).
