About Dolby Digital
The ESC333 features Dolby
Digital (also unofficially known
as AC-3) multichannel signal
processing, a system developed
by Dolby Laboratories.
Dolby Digital, unlike “matrixed”
systems (such as Dolby Pro
Logic) that derive and decode
multichannel sound from two
channels of sound, is capable of
delivering information for one
subwoofer and five full-range
channels as discrete and
individual channels in digital
AC-3 data format from sources
such as a DVD player. The result
is clear and accurate digital
sound to each speaker, along
with availability of stereo-
surround effects (Dolby Pro
Logic features mono surrounds).
Dolby Digital is capable of
delivering several different
formats of surround sound, the
most robust one being the 5.1-
channel mode, which provides
separate signals for five
satellite speakers as well as for
a subwoofer. The ESC333
features a “5.1-Ch” indicator
that illuminates when a Dolby
Digital 5.1-channel encoded
signal is present. Dolby Digital
can also provide other AC-3
digital multichannel signals, as
well as 2-channel signals, which
can be decoded via Dolby Pro
Logic processing into
multichannel surround sound.
In the latter case, both the
Dolby Pro Logic and Dolby
Digital indicators will illuminate
in the ESC333 display.
