Pro Logic
Pro Logic is set either to Manual or Automatic. In Automatic, the DP564
applies Pro Logic® decoding according to the setting of the Dolby Srnd metadata
parameter in a Dolby Digital 2/0 signal. You can use the front-panel buttons to apply
Pro Logic II as soon as the Dolby Digital 2/0 input is locked. If the metadata
parameter setting for Dolby Srnd is Not Indicated, or if the menu selection is
Manual, activation of Pro Logic decoding is entirely under your control using the
front-panel buttons.
Surround EX
Surround EX is set either to Manual or Automatic. Automatic applies
Dolby Digital Surround EX decoding according to the setting of the Surround EX
mode metadata parameter in a Dolby Digital 3/2 signal containing extended bitstream
information. If the metadata parameter setting for Surround EX is Not Indicated, or if
the menu selection is Manual, activation is under your control using the EX button.
To allow Surround EX decoding, your monitor configuration must include at least
one Back Surround speaker. Surround EX decoding can be applied only to Dolby
Digital signals with two surround channels. Other signal types automatically inhibit
Surround EX decoding.
Extended Bitstream
Extnd Bitstrm is set either to Enabled or Disabled. Enabled allows the
DP564 to use all metadata parameters including Extended Bitstream when decoding a
Dolby Digital bitstream. Disabled restricts the metadata parameters to the
parameters read by older consumer decoders. For more information about the two
categories of metadata, see Section A.5, Parameter Definitions.
Dolby Headphone Mode
Dolby H Mode controls the setting for Dolby Headphone processing. The settings
are Off, DH1 (Small Room), DH2 (Medium Room), and DH3 (Large
Room). Off produces a traditional stereo headphone sound.
The DH settings all process according to the downmix and listening mode selections.
For example, although Dolby Headphone technology can reproduce a full 5.1-channel
mix, if you have a stereo downmix selected, Dolby Headphone will process that
stereo downmix, and therefore there will only be two channels in the image.
