•When connecting an amplifier (with an optical digital input connector) which
does not contain the Dolby Digital (AC-3) decoder, be sure to select “PCM” at
“2 Dolby Digital” of the initial setting “6 Digital Audio Output”.(See page 60.)
•Otherwise any attempt to play DVDs may cause such a high level of noise that it
may be harmful to your ears and damage your speakers.
•Video CDs and CDs can be played as they would normally be played.

For your reference:
• Dolby Digital (AC-3) is a digital sound compression technique developed by the Dolby
Laboratories Licensing Corporation. Supporting 5.1-channel surround sound, as well as
stereo (2-channel) sound, this technique enables a large quantity of sound data to be effi
ciently recorded on a disc.
•Linear PCM is a signal recording format used in CDs. While CDs are recorded in
44.1 kHz/16 bit, DVDs are recorded in 48 kHz/16 bit up to 96 kHz/24 bit.
• If you have a Dolby Pro Logic Surround decoder, you will obtain the full benefit of Pro
Logic from the same DVD movies that provide full 5.1-channel Dolby Digital soundtracks,
as well as from titles with the Dolby Surround mark.
