34Surround Sound SystemsStereo reproduction normally uses left and right speakers, but Digital Theater Systems (DTS), Dolby Digital and DolbyPro Logic Surround go further, adding a centre and other channels so you are immersed in sound and special effects.Dolby Pro LogicDolby pro Logic Surround uses four channels of sound: left, right, centre anda rear channel, giving excellent reproduction of Pro Logic encoded trackswhen a compatible speaker system is connected to your TV. Most dialoguecomes from the centre channel, which enhances dialogue and focuses it soit seems to come from the action on screen. The rear channel is used toimmerse you in atmosphere and special effects, the same output is sent toboth rear speakers.As with Dolby Digital, Pro Logic is backwardly compatible with a conventionalstereo speaker setup.Digital Theater Systems (DTS) / Dolby DigitalBoth DTS and Dolby Digital split soundtrack information into 6 separate channelsof sound which are output through the speaker setup: five full range channels(left, center, right, left surround, right surround) and a ‘0.1’ (ie: limited range)bass channel. This gives you superb sound quality from DTS / Dolby Digitalencoded tracks when a compatible speaker system is connected to your TV.Most dialogue comes from the centre channel, which enhances dialogue andfocuses it so it seems to come from the action on screen. The separate rearleft and right channels give a dramatic sense of space, with sounds travellingin all directions between front, centre and rear channel speakers (eg: a rocketgoing overhead starts behind you to the left and explodes in front of you to theright). The ‘0.1’ Low Frequency Effects (LFE) channel gives impact to basssounds and to special effects more felt than heard (eg: the thud of a dinosaurfootfall or the rumble of thunder).While DTS and Dolby Digital are both high quality, ‘5.1’ channel surroundsystems, the two systems differ in how they break down and store soundinformation.They also differ in how they work with existing speaker setups: Dolby Digitalhas been developed to be backwardly compatible with Dolby Pro Logic andconventional stereo setups. DTS, on the other hand, focuses on the high quality,5.1 channel surround output; choosing not to develop backward compatibilitywith existing sound systems.Centre speakerFrontleftspeakerSubwoofer/LFE speakerRear leftsurroundspeakerFrontrightspeakerRear rightsurroundspeakerSurround SoundCentre speakerFrontleftspeakerRear leftsurroundspeakerFrontrightspeakerRear rightsurroundspeakerDTS/Dolby Digital setupDolby Pro Logic setupNote:• External equipment is usually connected to the TV via one of the AV terminalsto provide pictures and sound (eg: a VCR player connected to AV2). To receivea DTS or Dolby Digital encoded soundtrack from compatible equipment (eg: aDVD player, a set top box), you will also need to connect an optical or coaxialcable to one of the TVs digital audio sockets. See pages 12 to 13 for connectiondetails, also see the Digital Audio option in the SOUND menu, page 22.Notes:• To get Pro Logic information from Pro Logic encoded TV programmes, youmust be able to receive stereo transmissions. If stereo transmissions arenot transmitted in your area then the Pro Logic information will not be presenton TV transmissions and Pro Logic decoding will only produce a centrechannel output.• See pages 12 to 13 for connection details.
