*If the DVD disc contains an audio format of higher quality than 48kHz/16bit (maybe 96kHz/ 24bit), the player has to convert into a format compatible with DAT or MD.

**In this case you do not hear the highest sound quality possibly recorded on the disc (via the AUDIO OUT analog output neither).

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.
