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
this
unit,
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

jacks
to
this
unit.
(2) Dolby Pro Logic I
*
Dolby
Pro
Logic
II
is
a
new
multi-channel
playback
format
developed
by
Dolby
Laboratories
using
feedback
logic
steering
technology
and
offering
improvements
over
conventional
Dolby
Pro
Logic
circuits.
*
Dolby
Pro
Logic
II
can
be
used
to
decode
not
only
sources
recorded
in
Dolby
Surround
(2%)
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
II
offers
a
wider
band
range
(20
Hz
to
20
kHz
or
greater).
In
addition,
the
surround
channels
were
monaural
(the
surround
left
and
right
channels
were
the
same)
with
previous
Dolby
Pro
Logic,
but
Dolby
Pro
Logic
II
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
33).
% 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
makes
it
possible
to
achieve
multi-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-channel Dolby Digital signals
When
either
of
these
signals
is
input
to
the
AVR-1404/484,
the
surround
mode
is
automatically
set
to
Dolby.
