39Note• Some dts decoders which do not support DVD-dts interfacemay not work properly with the DVD/Video CD/CD player.For your reference:• Dolby Digital is a digital sound compression techniquedeveloped by the Dolby Laboratories, Inc. Supporting 5.1-channel surround sound, as well as stereo (2-channel) sound,this technique enables a large quantity of sound data to beefficiently recorded on a disc.• The digital theater systems (dts) is a 5.1-channel surroundsound system, which is widely used in movie theatres aroundthe world. It allows the bit rate to be increased in order to providegood sound quality without excessively compressing the data.• Linear PCM is a signal recording format used in a CD. While aCD is recorded in 44.1 kHz/16 bit, a DVD is recorded in 48kHz/16 bit up to 96 kHz/24 bit.• If you have a Dolby Pro Logic Surround decoder, you will obtainthe full benefit of Pro Logic from the same DVD movies thatprovide full 5.1-channel Dolby Digital soundtracks, as well asfrom titles with the Dolby Surround mark.• The digital audio output connector (optical) converts electricalsignals into optical signals and transfers them to an amplifier.These optical signals are immune from electrical interference,and they also have minimal effect on other equipment.Caution for the optional/coaxial digital audiooutput connector:• Do not connect to the digital audio input of an amplifierthat does not have Dolby Digital/dts/MPEG audiodecoder.• If such an amplifier should be connected to the playerwith “Bitstream” selected at the “2 Dolby digital”, “3 DTSDigital Surround” (see page 61), any attempt to play DVDs(or CDs recorded in dts) may cause such a high level ofnoise that it may be harmful to your ears and damageyour speakers.• Video CDs and CDs can be played as they would normallybe played.Manufactured under license from Dolby Laboratories.“Dolby”, “Pro Logic” and the double-D symbol aretrademarks of Dolby Laboratories.
