Друкувати сторінкуThe ATP8500.1 offers three different modes of Pro Logic II: Movie, Music, and DPL (original Pro Logic).
Movie: This mode is intended mainly for use with Dolby Surround-encoded material. Use it when you're
watching TV shows, VHS tapes, DVDs with Dolby Digital 2.0 or PCM soundtracks, and non-Dolby Digital
laserdiscs. It incorporates auto-balancing, which keeps dialogue locked to the center of the screen even if
left-to-right channel balance errors exist in the program material or in the source device (DVD player, VHS
deck, etc.). Movie mode requires no adjustments.
This mode is also appropriate for material specifically encoded for Pro Logic II, such as many games for
the Nintendo GameCube.
Music: Use this mode for CDs, FM stereo, satellite music channels, or other high-quality stereo music
sources. Music mode varies from Movie mode in that it does not use auto-balancing (because many music
recordings have vocals mixed to one side or the other), and it also incorporates a slight treble reduction in
the surround channels to keep the sound from becoming too "bright."
Music mode includes three special controls that let you tailor the sound to suit the recording, your speaker
system, or your personal taste. We'll discuss these modes later in this addendum. The ATP8500.1 comes
with these controls factory preset to sound good with most stereo material, so user adjustment is optional,
not mandatory.
DPL (Pro Logic): Similar to the original Pro Logic decoding introduced in the '80s, this mode remains
useful for low-quality stereo sources, such as audio cassettes, beat-up VHS tapes, or poorly received FM or
TV broadcasts. It combines Pro Logic II's stereo surround channels into a single mono surround channel
(as in original Pro Logic), and filters out frequencies above 7 kilohertz in the surround channel. These
alterations make the effects of noise, scratches, pops, etc., less noticeable.
DTS Neo: 6®
Neo: 6 produces surround sound from any stereo source: VHS tapes, TV broadcasts, DVDs with stereo
soundtracks, etc. It differs in one important way from Pro Logic II in that it produces up to 6.1 channels of
sound instead of 5.1, making use of the back surround speakers. Thus, it has the potential to produce more
dramatic surround effects. Although Neo: 6 and Pro Logic II perform the same basic function, they can
produce very different results. Using the surround mode selection buttons on the ATP8500.1's remote, you
can easily switch between Neo: 6 and Pro Logic II, and choose the one you like best.
The ATP8500.1 offers two Neo: 6 modes: Cinema and Music.
Cinema: This mode is intended mostly for surround-encoded material, such as most VHS tapes, many TV
shows, and most stereo DVDs. Cinema mode offers no adjustments.
Music: Use this mode with stereo CDs, FM stereo broadcasts, satellite music channels, and other stereo
music sources. Music mode differs substantially from Cinema mode in that it leaves the sound in the front
left and right channels unchanged, and adds extra ambience using the center and surround channels. As
with the Cinema mode, it offers adjustment of Center Image, which we will discuss shortly.
Concert
Concert is one of three new modes that expands on the original Music mode fond in the ATP8500. The
Concert mode uses the surround channels to add substantial ambience and reverb to stereo recordings,
much like the effect you would hear in a large concert hall. This mode works with any stereo music, from
sources such as CD, FM stereo, and satellite music channels. It is most appropriate for music that is
typically heard in a large auditorium, such as orchestral recordings and rock music. A reverb control in the
ATP8500.1's Audio Setup menu lets you adjust the reverberance to your liking.
Club
Club mode is essentially a more restrained version of Concert mode, with less reverb added and the
surround channels toned down substantially. Use this mode for music that might be heard in a smaller
