• When connecting an amplifier (with an optical/coaxial digital input )

which does not contain the Dolby Digital (AC-3) or DTS decoder, be
sure to select “PCM” at “Dolby Digital” and “DTS” of the initial setting
“Digital Audio Output” (see also page 27).
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.

• CD´s can be played as they would normally be played.

• Some DTS decoders which do not support DVD-DTS interface may not

work properly with the DVD/CD player.

• When you use optical digital audio cable, please remove dust protec-

tion cap from Optical Jack on the rear panel.

Both Dolby Digital and DTS are audio formats used to record 5.1-channel
audio signals onto the digital track of film. Both of these formats provide
six separate channels: left, right, center, left rear, right rear, and common
subwoofer.

Remember, that Dolby Digital or DTS will only play 5.1-channel sound if
you’ve connected a DTS or Dolby Digital receiver or decoder and if the
disc was recorded in the Dolby Digital or DTS format.

• Remove the dust protection cap from the optical digital audio output

and connect the cable firmly so that the configurations of both the

Notes when connecting the optical digital audio cable (optional)

• Dolby Digital (AC-3) is a digital sound compression technique devel-

oped 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 connected to the

DVD10’s analog AUDIO OUT connectors, 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.
