Dolby Digital
™
Dolby Digital discs support recordings of up to 5.1 channels of digital signals,
which reproduce much better sound quality, spatial expansion, and dynamic
range characteristics than the previous Dolby Surround effects.
Dolby Digital EX
™
This mode uses a matrix decoder to create the back (sometimes referred
to as surround center) signal from the surround left and right signals in a
Dolby Digital 5.1 channel source and provides 6.1 channel surround
playback. For the best results, this mode should be selected during playback
of sources recorded in Dolby Digital Surround EX.
When Dolby Digital EX sources are decoded with a Dolby Digital EX
decoder, the format is automatically detected and Dolby Digital EX mode
is selected. However, some Dolby Digital EX sources may be detected as
Dolby Digital sources. In this case, the Dolby Digital EX mode should be
selected manually.
Dolby Pro Logic
™
Dolby Pro Logic is a specially encoded two-channel surround format which
consists of four channels (front left, center, front right, and surround). The
surround channel is monaural and is played through both surround
speakers.
Dolby Pro Logic II
™
surround
This mode applies conventional two-channel signals such as digital PCM
or analog stereo signals as well as Dolby Surround signals to surround
processing. Dolby Pro Logic II surround includes Dolby Pro Logic II Cinema,
Dolby Pro Logic II Music, and Dolby Virtual signal formats.
MPEG
™
Multichannel
Though the number of audio channels is 5.1 (which is the same as Dolby
Digital), MPEG Multichannel
discs are much better at matching individual
sounds to the correct position in the sound stage. MPEG Multichannel works
well when using the 7 CH DIRECT INPUTs to playback the sound from an
additional multichannel decoder. For details, see to the user’s guide for your
connected 7-channel component.
