Note
If the source is a 2-channel LPCM or Dolby Digi-
tal audio source, we recommend turning Dolby
Pro Logic II on when selecting SFC effects that
are most suitable for 5.1-channel audio sources
(such as Musical, Drama or Action).
On the other hand, when selecting SFC effects
that are suitable for 2-channel audio sources
(such as Jazz, Hall or Club), we recommend
turning Dolby Pro Logic II off.
