Thesignals within each channel are distinct from the others,allowing pinpoint sound imaging, and Dolby Digital offerstremendous dynamic range from the most powerful soundeffects to the quietest, softest sounds, free from noise anddistortion.No. recorded channels(elements)No. playback channelsPlayback channels(max.)Audio processingHigh frequencyplayback limit ofsurround channel5.1 ch5.1 chL, R, C, SL, SR, SWDigital discreteprocessing DolbyDigital encoding /decoding20 kHz2 ch4 chL, R, C, S(SW – recommended)Analog matrixprocessing DolbySurround7 kHz2 Dolby Digital and Dolby Pro Logic2 Dolby Digital compatible media and playback methodsMarks indicating Dolby Digital compatibility:The following are general examples.

Inaddition, the surround channels were monaural (the surroundleft and right channels were the same) with previous Dolby ProLogic, but Dolby Pro Logic II they are played as stereo signals.Sources recorded in Dolby Surround• These are sources in which three or more channels of surroundhave been recorded as two channels of signals using DolbySurround encoding technology.• Dolby Surround is used for the sound tracks of movies recordedon DVDs, LDs and Video cassettes to be played on stereoVCRs, as well as for the stereo broadcast signals of FM radio,TV, satellite broadcasts and cable TV.• Decoding these signals with Dolby Pro Logic II makes itpossible to achieve multi-channel surround playback. Thesignals can also be played on ordinary stereo equipment, inwhich case they provide normal stereo sound.• There are two types of DVD Dolby surround recording signals.q 2-channel PCM stereo signalsw 2-channel Dolby Digital signalsManufactured under license from Dolby Laboratories.“Dolby”, “Pro Logic” and the double-D symbol aretrademarks of Dolby Laboratories.2 Sources recorded in Dolby Surround are indicated withthe logo mark shown belowDolby Surround support mark:
