stereo reproduction normally uses left and right speakers, but Digital Theater System and Pro Logic Surround
go further, adding a centre and other channels so you are immersed in sound and special effects."
Digital Theater Systems (DTS) / Dolby Digital
Both DTS and Dolby Digital split soundtrack Information into 6
separate channels of sound which are output through the speaker
setup: five full range channels (left, center, right, left surround, right
surround) and a 'O.T (i.e.: limited range) bass channei. This gives
you superb sound quality from DTS / Dolby Digital encoded tracks
when a compatible speaker system is connected to your TV. Most
dialogue comes from the centra channel, which enhances dialogue
and focuses it so it seems to come from the action on screen. The
separate rear left and right channels give a dramatic sense of
space, with sounds travelling in all directions between front, centre
and rear channel speakers (e.g.: a rocket going overhead starts
behind you to the left and explodes in front of you to the right). The
'0.1’ IQVJ Frequency Effects (LFE) channel gives impact to bass
sounds and to special effects more felt than heard (e.g.: the thud of
a dinosaur footfall or the rumble of thunder). While DTS and Dolby
Digital are both high quality, ‘5.1’ channel surround systems, the
two systems differ in how they break down and store sound
information They also differ in how they work with existing speaker
setups. Dolby Digital has been designed to be backwardly
compatible with Dolby Pro Logic and conventional stereo setups.
DTS on the other hand, focuses on the high quality, 5.1 channel
surround output choosing not to develop backward compatibility
with existing sound systems.

Note:
External equipment is usually connected to the TV via one of the AV terminals to provide pictures and sound
(e.g. a VCR player connected to AV2). To receive a DTS or Dolby Digital encoded soundtrack from compatible
equipment (e.g.; a DVD player, a set top box) you will also need to connect an optica! or coaxial cable to one of
the TV’s digital audio sockets. See page 41 for connection details. Also see the Digital Audio option in the
SOUND menu, page 17.
Dolby Fro Logic
Dolby Pro Logic surround uses four channels of sound: left, right,
centre and a rear channel giving excellent reproduction of Pro
Logic encoded tracks when a compatible speaker system is
connected to your TV. Most dialogue comes from the centre
channel, which enhances dialogue and focuses it so It seems to
come from the action on screen. The rear channel is used to
immerse you in atmosphere and special effects, the same output Is
sent to both rear speakers.
As with Dolby Digital, Pro Logic is backwardly compatible with a
conventional stereo speaker setup.

present on TV transmissions and Pro Logic decoding wiH only produce a centre channei output.
