Dolby Pro Logic is a decoding system that was
developed to get a better sense of presence from
sources encoded with Dolby Surround. The
feeling of position has been improved by the
addition of a separate center speaker channel.
Dolby Surround was developed to allow
enjoyment of Dolby Stereo, a cinema system, in
private homes. This system reproduces sound
close to that of the original movie through use of
an analog matrix.
This unit has two types of Dolby Pro Logic.
• SURROUND: the surround speakers are
used.
• 3 STEREO: the surround speakers are not
used.

channels. Some sources marked Dolby Digital
may be recorded in Dolby Surround, a 2 channel
system.
