Tektronix WFM8200 - Table 6: Channel Modes Versus Listening Modes

Audio Monitoring
Pro Logic Phant
om. 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 s urround 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 w ill be decoded to provide LCRS channels where the surround
channel is reduced 3 dB and reproduced in both the Ls and Rs bars.
