³Underlined items are factory preset.
¤1 Select “No” if the digital audio input terminal of your audio equipment (AV amplifier, etc.) can handle 96 kHz/24 bit signal. If it is not acceptable
for 96 kHz/24 bit digital audio signal, or the 96 kHz linear PCM disc you want to play is copyright-protected, it is recommended to set “1 No” and
make analog connection to enjoy high quality sound (If it is set to “Yes”, the player converts linear PCM to 48 kHz even during analog output).
¤2 When connecting an amplifier (with an optical digital input terminal) which does not contain a Dolby Digital or DTS Digital Surround decoder, be
sure to select “PCM” at “2 Dolby Digital” and “Off” at “3 DTS Digital Surround”. If “Bitstream” is selected, any attempt to play DVDs (or CDs
encoded with DTS) may cause a high level of noise that can injure your ears and damage your speakers.
For your reference
³Dolby Digital is a digital sound compression technique developed by Dolby Laboratories.
Supporting 5.1-channel surround sound, as well as stereo (2-channel) sound, this technique enables a large quantity of sound data to be efficient-
ly recorded on a disc.
³DTS Digital Surround is a 5.1-channel surround sound system, which is widely used in movie theaters around the world. The separation between
channels is good and provides a very real surround effect.
³Linear PCM is an uncompressed digital audio signal. While a CD is recorded in 44.1 kHz/16 bit, a DVD is recorded in 48 kHz/16 bit up to 96 kHz/
24 bit. Therefore, the sound reproduced with these signals is potentially better than that found on CDs. This player reproduces linear PCM in two
channels.
³Bitstream is a compressed digital audio signal. This signal can be decoded into different channels to produce, for instance, 5.1-channel surround
sound.
³The digital audio output terminal (optical) converts electrical signals 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.
³These changes to digital audio output must be made, otherwise bitstream signals the decoder cannot handle will be output. If these
signals are output, “noise” will be output which can cause harm to your ears and speakers.
Note
³You cannot use DTS Digital Surround decoders not suited to DVD.
