Surround
The S-302 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
Dolby Digital
Dolby Digital is a multichannel digital signal format developed by Dolby
Laboratories.
A total of 5.1-channels are played: 3 front channels (“FL” , “FR” and
“C”), 2 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.
Dolby Pro Logic g
Dolby Pro Logic g 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.
