Pro Logic Phantom. Pro Logic Phantom creates a Lt/Rt downmix of any input
with three or more channels. This Lt/Rt downmix will then use Pro Logic
decoding to produce a surround channel and provide LCS surround channels. This
surround channel is reduced 3 dB and reproduced in both the Ls and Rs bars.
A 2/0 encoded Dolby stream will be assumed to be Pro Logic encoded already and
will be Pro Logic decoded to produce a LRS output. Again, the surround channel
is reduced 3 dB and reproduced in both the Ls and Rs bars.
Any PCM input will be decoded to provide LCRS channels where the surround
channel is reduced 3 dB and reproduced in both the Ls and Rs bars.
