Esc333 Speaker, Source & Remote Sensor Connections; About Dolby Digital - JBL SUB333 Service Manual

Dolby Pro-Logic Surround Processor/Amplifier/Subwoofer
Ò
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.
