| Reproduction modes
All the reproduction modes mentioned below can be effective only
when digital signals are input as a sound source.
Dolby Digital (AC-3) mode
“Dolby Digital” is the official term for the “AC-3” mode, and it is a
system developed by Dolby Laboratories to transmit the “5-plus-1-
channel” digital signals altogether.
Whereas Dolby Pro Logic is an analog matrix system, Dolby Digital
(AC-3) employs a “digital discrete system” in which each channel is
treated as a separate entity. It is used for the DVDs which are a
new-generation AV media, and it represents the new format which
supports not only laser discs but also the advances which will be
made in AV components of the future.
This mode is used to enjoy digital sources, such as music sources or
movie software (DVD having the following mark).

Dolby Pro Logic mode
Dolby Pro Logic lets you enjoy movie software (laser discs having the
following mark), in your own home with the same powerful stereo-
phonic effect found in movie theaters.
Qc surnu]
This unit has two Dolby Pro Logic modes: the SURROUND mode
and the 3 STEREO mode.
SURROUND mode E]
By reproducing the feeling of depth and movement of sound, video
software or compact discs recorded with Dolby Surround provide
the listener with a feeling of presence like that of a movie theater.
3 STEREO mode
You can enjoy audio/video sources with clear sound, more presence
and a good feeling of orientation. 3 STEREO can be used with stereo
sources not encoded with DOLBY SURROUND.
Stereo mode
This mode is used to replay program sources which were recorded in
a format other than Dolby Surround. If the input signals are in the
Dolby Digital (AC-3) format, they are down-mixed (see below) into
2 channels.
Down-mixing function
This function mixes the 5-plus-1-channel input signals into the 2-
channel format and outputs the result. It achieves an effect very
similar to reproduction in the AC-3 mode.
