The ESC340 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 multichannel
sound from a two-channel
source, 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 ESC340
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. 

DIGITAL SURROUND
THE FINEST 5 .1 SURROUND
SOUND TECHNOLOGY ON THE
MARKET TODAY!
An amazing new technology for
surround-sound entertainment,
DTS Digital Surround is an
encode/decode system that
delivers six channels (5.1) of
master-quality,20-bit audio. 

In the encoding process, the
DTS algorithm encrypts six
channels of 20-bit digital audio
imformation in the space
previously allotted for ouly two
channels of 16-bit linear PCM.
Then during playback, the DTS
decoder reconstructs the
original six channels of 20-bit
digital audio. 

Each of these six channels is
audibly superior to the 16-bit
linear PCM audio found on
conventional compact discs.

• Wall-mount brackets and floor

stands available separately
for the satellites.

• Credit-card-type, full-

function remote control.

• JBL “error free” speaker

cables simplify connection 
and eliminate possibility of
out-of-phase wiring.

• Center foot for horizontal

placement of the center 
channel.

• Rotatable JBL logos to allow

for vertical or horizontal
placement of the satellites.
