Caution for the optical / coaxial digital audio output connector:
• When connecting an amplifier (with an optical/coaxial digital input connector) which does not
contain the Dolby Digital decoder or DTS decoder, be sure to select:
- “Dolby Digital” = PCM
- “DTS” = Off
of the initial setting “Digital Audio Out”. (See above.)
Do not use ...
the “Digital Audio Out” jacks to connect to an equipment other than a Dolby Digital, DTS,
or MPEG 2 receiver or a suitable decoder. Such a connection can create a high level of noise that
may be harmful to your ears, and could damage headphones or speakers. Older digital
equipment, some of which are not fully compliant with IEC 958, are likely to cause this problem.
If you encounter this problem, use the “digital audio out” menu (see above) to convert the Dolby
Digital digital audio bitstream output to linear PCM. The same should be applied with the so-called
“optical or coaxial REC.OUT jack” of Dolby Digital decoders, when they are connected to this DVD
player. Since REC.OUT is a 1: 1 copy of the decoder's input, no other equipment should be connected
there.
According to the audio devices connected to the digital output of this player (coaxial or optical),
select one of these options.
• See also the Audio connection pages 12-15.
