Please use a commercially
available adapter when connecting
the Dolby Digkal RF output jack of the
LD player to the digital input jack
Please refer to the instruction

Some DVD digital outputs
have the function
of switching
the Dolby Digital signal output
method
between
"bit stream"
and "(convert
to) PCM"
When playing in Dolby Digital surround
on the AVR-
2803, switch the DVD player's output mode to "bit stream"
In some cases players are equipped with
both "bit stream + PCM" and "PCM only"
digital outputs
In this case connect the "bit stream +
PCM" iacks to the AVR-2863

Dolby Pro Logic ]1

Do]by
Pro Logic l] _s a new
multi-channel
playback
format
developed
by Dolby
Laboratories
using
feedback logic steering technology
and offering improvements over conventional
Dolby Pro Logic circuits
•
Do]by Pro Logic [1 can be used to decode
not only sources
recorded
in Dolby Surround
(_)
but also
regular stereo sources into five channels (front left, front right, center, surround
left and surround
right) to
achieve surround sound
•
Whereas with conventional
Dolby Pro Logic the surround channel playback frequency
band was limited,
Dolby Pro Logic ]] offers a wider band lunge
(20 Hz to 20 kHz or greater)
hi addition,
the surround
channels were monaural
(the surround
left and right channels were the same) with
previous
Dolby Pro
Logic, but Dolby Pro Logic ]I they are played as stereo signals
• Various parameters
can be set according
to the type of source and the contents,
so it is possible to
achieve optimum
decoding
(see page 28)
Sources recorded
in Dolby Surround
These are sources in which three or more channels of surround
have been recorded as two channels of
signals using Dolby Surround encoding
technology
Dolby Surround is used for the sound tracks of movies recorded
on DVDs, LDs and Video cassettes
to
be played on stereo VCRs, as well as for the stereo broadcast signals of FM radio, TV, satellite broadcasts
and cable TV
Decoding
these signals
with
Dolby Pro Logic l] makes
it possible to achieve
muk[-channel
surround
playback
The signals can also be played on ordinary
stereo
equipment,
in which
case they provide
normal stereo sound
There are two types of DVD Dolby surround
recording signals
_
2-channel PCM stereo signals
_2) 2-channel Dolby Digital signals
When either of these signals is input to the AVR-2803, the surround mode is automatically
set to Dolby
Pro Logic _] when the "DOLBY/DTS
SURROUND"
mode is selected

Digital Theater
Surround
(also called simply DTS) is a multi-channel
digital signal format developed
by Digital
Theater
Systems
DTS offers the same "51 " playback channels as Dolby Digital (front left, front right and center, surround left and
surround right) as well as the stereo 2-channel mode The signals for the different
channels are fully independent,
eliminating
the risk of deterioration
of sound quality due to inter[erence
between
signals, crossfalk, etc
DTS features
a relatively higher bit rate as compared
to Dolby Digital (1234 kbps for CDs and LDs, 1536 kbps for
DVDs) so it operates
with a relatively
low compression
rate
Because of this the amount of data is great, and
when
DTS playback is used in movie theaters,
a separate CD-ROM
synchronized
with the film is played
With
LDs and DVDs, there
is of course no need for an extra disc; the pictures and sound can be recorded
simultaneously
on the same disc, so the discs can be handled in the same way as discs with other formats
There are also music CDs recorded in DTS These CDs include 5 1-channel surround
signals (compared
to two
channels on current CDs) They do not include picture data, but they offer surround playback on CD players that
are equipped
with digital outputs (PCM type digital output
required)
DTS surround
track playback
offers the same intricate,
grand sound as in a movie theater,
right in your own
listening room

DTS signals are recorded
in the same way on CDs and LDs as PCM signals
Because of this, the un-
decoded DTS signals are output as random
"hissy"
noise from the CD or LD player's analog outputs
If
this noise _s played with the amplifier
set at a very high volume,
it may possibly
cause damage
to the
speakers
To avoid this, be sure to switch the input mode to "AUTO"
or "DTS" before playing CDs or LDs
recorded in DTS Also, never switch
the input mode to "ANALOG"
or "PCM"
during playback
The same
holds true when
playing CDs or LDs on a DVD player or LD/DVD compatible
player
For DVDs, the DTS
signals are recorded
in a special way so this problem
does not occur
The signals provided at the digital outputs
of a CD or LD player may undergo some sort of internal
signal
processing
(output level adjustment,
sampling frequency
conversion,
etc)
hi this case the DTS-encoded
signals may be processed
erroneously,
in which case they cannot be decoded by the AVR-2903, or may
only produce noise
Before playing DTS signals for the first time, turn down the master volume to a low
level, star[ playing the DTS disc, then check whether
the DTS indicator on the AVR-2863 (see page 36)
lights before turning up the master volume
A DVD player with DTS-compafible
digital output is required to play DTS DVDs
A DTS Digital Output logo
is featured on the front panel of compatible
DVD players
Recent DENON DVD player models feature DTS-
compatible
digital output - consult the player's owner's
manual for information
on configuring
the digital
output
for DTS playback of DTS-encoded DVDs
