Dolby Pro Logic Surround
Decoding svstem of Dolbv Surround sound
standardized in TV programs and movies.
Compared with the former Dolby Surround
system, Dolby Pro Logic Surround improves
sound image bv using four separate channels:
off-screen audio effects, on-screen dialog,
Icft-to-right panning, and music. These
channels manipulate the sound to be heard
and enhance the action as it happens on the
screen. To take advantage of Dolby Pro Logic,
you should have at least one pair of rear
speakers and/or one center speaker. You also
need to select the appropriate center mode to
enjoy a full effect.
Dolby Surround
Encoding and decoding system of Dolby
Surround sound for consumer use. Dolby
Surround decodes the extra channels on the
Dolby Surround-encoded sound tracks of
movie videos and TV programs and produces
sound effects and echoes that make the action
seem to envelop you.
The amplifier offers Dolby Surround as one
of the pre-programmed sound fields. If you
have rear or center spcaker(s), we
recommend that you customize the Dolby
Surround sound field by selecting the
appropriate center mode to take advantage of
Dolby Pro Logic Surround sound.
Parameter
Variable of sound that composes sound
image, such as tone or delay time. You can
customize the pre-programmed sound fields
by adjusting parameters to suit your listening-
situation.
