24Stereo reproduction normally uses left and right speakers, but Digital Theater Systems (DTS), Dolby Digital and Dolby ProLogic Surround go further, adding a centre and other channels so you are immersed in sound and special effects.Digital Theater Systems (DTS) / Dolby DigitalBoth DTS and Dolby Digital split soundtrack information into 6separate channels of sound which are output through the speakersetup: five full range channels (left, centre, right, stereo left andright surround) and a ’0.1’ (ie: limited range) bass channel. Thisgives you superb sound quality from DTS / Dolby Digital encodedtracks when a compatible speaker system is connected to yourTV.Most dialogue comes from the centre channel, which enhancesdialogue and focuses it so it seems to come from the action onscreen. The separate rear left and right channels give a dramaticsense of space, with sounds travelling in all directions betweenfront, centre and rear channel speakers (eg: a rocket goingoverhead starts behind you to the left and explodes in front of youto the right). The ’0.1’ Low Frequency Effects (LFE) channel givesimpact to bass sounds and to special effects more felt than heard(eg: the thud of a dinosaur footfall or the rumble of thunder).While DTS and Dolby Digital are both high quality, ’5.1’ channelsurround systems, the two systems differ in how they break downand store sound information.They also differ in how they work with existing speaker setups:Dolby Digital has been developed to be backwardly compatiblewith Dolby Pro Logic and conventional stereo setups. DTS, on theother hand, focuses on the high quality, 5.1 channel surroundoutput; choosing not to develop backward compatibility withexisting sound systems.Note:D External equipment is usually connected to the TV via one ofthe Scart sockets to provide pictures and sound (eg: a VCRplayer connected to AV2). To receive a DTS or Dolby Digitalencoded soundtrack from compatible equipment (eg: a DVDplayer, a set top box), you will also need to connect an opticalor coaxial cable to one of the TVs digital audio sockets. Seepages 27 to 28 for connection details, also see the DigitalAudio option in the SOUND menu, page 9.Dolby Pro LogicDolby Pro Logic Surround uses four channels of sound: left, right,centre and a mono rear channel, giving excellent reproduction ofPro Logic encoded tracks when a compatible speaker system isconnected to your TV. Most dialogue comes from the centrechannel, which enhances dialogue and focuses it so it seems tocome from the action on screen. The rear channel is used toimmerse you in atmosphere and special effects, the same outputis sent to both rear speakers.As with Dolby Digital, Pro Logic is backwardly compatible with aconventional stereo speaker setup.Notes:D To get Pro Logic information from Pro Logic encoded TVprogrammes, you must be able to receive stereotransmissions. If stereo transmissions are not transmitted inyour area then the Pro Logic information will not be present onTV transmissions and Pro Logic decoding will only produce acentre channel output.D See pages 27 to 28 for connection details.Surround sound systemsCentre speakerCentre speakerSubwoofer /LFE speakerRear rightsurroundspeakerRear leftsurroundspeakerFrontrightspeakerFrontleftspeakerRear rightsurroundspeakerRear leftsurroundspeakerFrontrightspeakerFrontleftspeaker
