surround modes: stereo, Pro Logic. Pro Logic II
STEREO
Downmix
Down-mixes a digital multi-channel signal, e.g. Dolby Digital or DTS, to a two channel stereo signal
(front left and right) only.
PRO LOGIC
Applies Dolby Pro Logic decoding. This may be applied to any stereo source to give multi-channel
surround sound
(1)
. If you have a ‘7.1’ system set-up, then you can optionally reproduce PRO LOGIC’s
surround information through the ‘normal' surround loudspeakers, the back channels or both. For
more details see page 63.
PRO LOGIC
can be set to work with or without a subwoofer.
This is done in the
Bass Redirection Rules
found in the subwoofer configuration screen,
see page 61.
PRO LOGIC IIx
Pro Logic IIx is a combination of Dolby’s acclaimed Pro Logic II processing and Dolby Digital
Surround EX, with a few extra wrinkles thrown in for best sound quality - be it 5.1, 6.1 or even 7.1.
Pro Logic II reduced the performance gap between Pro Logic and discrete Dolby Digital 5.1 by
creating five full-bandwidth output channels from 2-channel sources. Pro Logic IIx extends the already
highly sophisticated Pro Logic II algorithms to process native stereo and 5.1-channel content to
produce 6.1 or 7.1 output channels.
Pro Logic IIx modes are only available if your system setup includes back speaker(s), otherwise the
modes revert to Pro Logic II.
Pro Logic IIx processing can be applied to all two channel sources, plus Dolby Digital 5.1 and even
material encoded with Dolby Digital Surround EX.
Three modes are available:
PRO LOGIC IIx MOVIE
,
PRO LOGIC IIx MUSIC
and
PRO LOGIC IIx GAME
.
PRO LOGIC IIx MUSIC
This mode gives music a more three dimensional representation, providing more spaciousness and
transparency and generating 6.1 or 7.1 output from stereo or multi-channel material.
When processing stereo material the mode appears as PLIIx MUSIC, with multi-channel material the
mode will be shown as, for example, DD5.1+PLIIx MUSIC. PL IIx MUSIC can be user configured to
suit your taste and listening environment, for details see
page
66.
PRO LOGIC IIx MOVIE
This mode improves the sound quality, channel separation and steering of Stereo, Dolby Surround
and Dolby Pro Logic (or similar) matrix encoded movie soundtracks, and generates Surround Back
channel information from multi-channel Dolby Digital soundtracks.
When processing stereo material the mode appears as PLIIx MOVIE, with multi-channel material the
mode will be shown as, for example, DD5.1+PLIIx MOVIE. PLIIx MOVIE is optimised for movie and
television soundtracks and does not allow any user configuration.
PRO LOGIC IIx GAME
This is a special mode to allow those who use their Home Cinema systems to enjoy video games to
get an even better gaming experience. The Game mode is specially tuned to ensure that the full bass
impact from surround effects in a game are delivered to the subwoofer - explosions shake the room
like never before!
1. Some Dolby Digital-encoded discs contain control information to allow the AV32R ‘Dual Processor’ to detect PRO LOGIC automatically.
