Dolby Surround support mark:
Manufactured under license from Dolby Laboratories. “Dolby”,
“Pro Logic” and the double-D symbol are trademarks of Dolby

The AVR-487 is equipped with a digital signal processing circuit that
lets you play program sources in the surround mode to achieve the
same sense of presence as in a movie theater.

Dolby Surround
[1] Dolby Digital
Dolby Digital is the multi-channel digital signal format developed by
Dolby Laboratories.
A total of 5.1-channels are played: three front channels (“FL”, “FR”
and “C”), two surround channels (“SL” and “SR”) and the “LFE”
channel for low frequencies.
Because of this, there is no crosstalk between channels and a realistic
sound field with a “three-dimensional” feeling (sense of distance,
movement and positioning) is achieved.
A real, overpowering sense of presence is achieved when playing
movie sources in AV rooms as well.
[2] Dolby Pro Logic II
Dolby Pro Logic II is a matrix decoding technology developed by
Dolby Laboratories. Regular music such as that on CDs is encoded
into 5 channels to achieve an excellent surround effect.
The surround channel signals are converted into stereo and full band
signals (with a frequency response of 20 Hz to 20 kHz or greater) to
create a “three-dimensional” sound image offering a rich sense of
presence for all stereo sources.

DTS Digital Surround
DTS Digital Surround is a digital surround format developed by Digital
Theater Systems of the United States.
The number of playback channels and the playing band is the same as
for Dolby Digital (5.1-channels).
The compression rate of the audio data when it was recorded on the
medium is lower than for Dolby Digital, so there is more information
when the data is decoded, resulting in richer, clearer sound quality.
