DIGITAL AUDIO CONNECTIONS 15Digital Audio ConnectionsAudio output from the unit’soptical/coaxial digital audiooutput connector* Digital Format must be selected as“ORIGINAL“ or ”PCM” respectively in MenuFor your reference: Dolby Digital (AC-3) is a digital sound com-pression technique developed by the DolbyLaboratories Licensing Corporation,supporting 5.1-channel surround sound, aswell as stereo (2-channel) sound, this tech-nique enables a large quantity of sound datato be efficiently recorded on a disc. Linear PCM is a signal recording format usedin CDs. While CDs are recorded in44.1 kHz/16 bit, DVDs are recorded in48 kHz/16 bit up to 96 kHz /24 bit. If you have a Dolby Pro Logic Surrounddecoder connected to the DVD’s analogAUDIO OUT connectors, thanks to the”Downmix” function of the DVD you willobtain the full benefit of Pro Logic from thesame DVD movies that provide full 5.1-chan-nel Dolby Digital soundtracks, as well as fromtitles encoded with Dolby Surround. The DVD is designed to digitally output96 kHz-PCM audio with a 96 kHz samplingrate. However, some 96 kHz DVD's mayinclude copy protection codes that do notpermit digital output. For full 96 kHz fidelityfrom these discs, use the analog outputs ofthe DVD.IMPORTANT: If your surround processor/D/Aconverter does not support 96 kHz PCM audio,you must use the DVD analog outputs for full 96kHz fidelity with these discs.Caution for the optical/coaxialdigital audio outputs: When connecting an amplifier (with an opti-cal/coaxial digital input ) which does not con-tain a Dolby Digital (AC-3) or DTS decoder, besure to select ”PCM” as initial setting in the”Digital Output” menu (see also page 18).Otherwise, any attempt to play a DVD maycause such a high level of noise that it maybe harmful to your ears and damage yourspeakers. CD´s can be played as they would normally beplayed.Note: Some first generation DTS decoders which donot support DVD-DTS interface may not workproperly with the DVD/CD player.Notes when connecting theoptical digital audio cable(optional) Remove the dust protection cap from theoptical digital audio output and connect thecable firmly so that the configurations of boththe cable and the connector match. Keep the dust protection cap and alwaysreattach the cap when not using the connec-tor.Dolby Digital and DTSBoth Dolby Digital and DTS are audio formatsused to record 5.1-channel audio signals ontothe digital track of film.
