Dolby Digital
This format provides 5.1-channel surround sound. Dolby Digital source mate-
rial includes DVDs, digital TV broadcasts, many PlayStation 2
®
video games,
all Xbox

video games, laserdiscs, some cable and satellite programs, digital
cable programming, and D-VHS tapes.
Dolby Digital EX
Dolby Digital Surround EX-encoded soundtracks contain an extra back
surround channel that’s been added to the soundtrack during mixing. This
additional channel places audio directly behind the listener to provide more
detailed imaging, enhanced depth, better ambience, and more precise sound
localization. You can play this “back” channel through one or two additional
surround speakers. There’s a list of Dolby Digital EX-encoded movies on the
Dolby web site,
www.dolby.com
.
You can use Dolby Digital EX to play back non-EX encoded material but the
results probably won’t be precisely what you might expect. Instead, we recom-
mend that you use Dolby Digital +
Pro Logic IIx-C
(movie mode) for more
predictable results.
Dolby Pro Logic IIx
Dolby Pro Logic Ilx is the most recent version of Dolby Pro Logic decoding. Pro
Logic II was a substantial improvement over original Pro Logic and Pro Logic
IIx is the 7.1-channel version of Pro Logic II. You can use it only when you’ve
got back surround speakers connected to the Model 970. Otherwise, the Model
970 provides standard Pro Logic II processing.
Pro Logic IIx’s Movie mode
is excellent for decoding Dolby Surround-encoded
movie and TV soundtracks. It also works well with video games, especially those
encoded in Pro Logic II. Use this mode for VHS tapes, standard TV broadcasts,
and DVDs encoded in Dolby Digital 2.0.
The Pro Logic IIx Music mode
converts stereo music into surround sound.
Use it with any stereo music source, including CDs, FM radio, and MP3 play-
ers. The Music mode includes three controls, which are adjustable through the
Model 970's Surround Configuration sub-menu: They are:
Panorama:
Extends the front stereo image to the surround speakers for a
“wraparound” effect.
Dimension:
Lets you correct for “dry” recordings by extending the soundfield
towards the back of the listening/viewing area and to decrease apparent rever-
beration by “collapsing” the image towards the front.
Center Width:
This blends sound from the center channel into the left and right
channels to create a more seamless front soundstage. You can vary the effect from
one extreme (where the center channel speaker is shut off and only a “phantom”
signal derived from the left and right speakers remains) to the other (where only
the center channel speaker reproduces center channel information.)
The Pro Logic IIx Game mode
sends surround channel bass signals to the
subwoofer to preserve visceral impact.
Pro Logic IIx processing also works with 5.1-channel material, either Dolby
Digital or DTS, to create 7.1-channel sound. This mode is shown in the front
panel and on-screen displays as “ProLogicIIx-X
