Here we describe
a number of speaker settings
for different
purposes
Use these examples
as guides to set up
your system according to the type of speakers used and the main usage purpose
(1} Basic setting
Use this setting if your main purpose [s to listen to movie music and when using one set (two speakers) of
regular single-way or two way speakers as the surround
speakers
F Fron_ speakers

Momtor
As seen f:om
above
• Set the front speakers with
their front surfaces as
flush
wgh the TV or monitor
screen as possible
Set the center
speaker between
the front left and
right speakers
and no further
from the listening
position than the front speakers
• Consult
the owner's
manual
for your subwoofer
for advice on placing the
subwoofer
within
the
listening room
• If the
surround
speakers
are direct-radiating
(monopohr)
then place them slightly behind and at
an angle to the listening position
and parallel to the
walls at a position 60 to 90 centimeters
{2 to 3 feet)
above ear level at the prime listening position
seen f:om
the side
(2} Using diffusion type speakers for the surround speakers
For the greatest
sense of surround
sound envelopment,
diffuse
radiation speakers such as bipolar types, or
dipolar types, provide a wider dispersion
than is possible to obtain from a direct radiating speaker (monopohr)
Place these speakers at either side of the prime listening position, mounted
above ear level
Pathof thesurround soun_l fromthe • Set the front speakers, center speaker and subwoofer
speakers tothe listeningposition
in the same positions
as in example
11)
• Set the surround
speakers
directly at the sides of
the listening
position
and 60 to 90 centimeters
{2
to 3 feet) above ear level
• The signals from the surround
channels
reflect off
the walls
as shown
on the diagram

creating an enveloping
and realistic surround sound

The AVRq 603 is equipped with a digital signal processing circuit that lets you play program sources in the surround
mode to achieve the same sense of presence as in a movie theater
Dolby Surround
(1)
Dolby Digital (Dolby Surround AC-3)
Dolby Digital is the muki-channel
digital signal format developed
by Dolby Laboratories
Dolby Diggal consists
of up to "51 " channels - front left, front right, center, surround
left, surround
right,
and an addgional channel exclusively
reserved
for additional
deep bass sound effects
{the Low Frequency
Effects - LFE - channel, also called the "1 " channel, containing
bass frequencies
of up to 120 Hz)
Unlike the analog Dolby Pro Logic format,
Dolby Digital's
main channels can all contain
full range sound
information,
from the lowest bass, up to the highest frequencies
- 22 kHz The signals within each channel
are distinct from the others, allowing
pinpoint sound imaging, and Dolby Digital offers tremendous
dynamic
range from the most powerFul sound effects to the quietest,
softest sounds, free from noise and distortion

available adapter when connecting
the Dolby Digital RF (AC-3RF) output jack
of the LD player to the digital input iack
Please refer to the instruction
manual of the adapter when making connection
2 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 AVRq 603, 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" jacks to the AVR_
1603
(2} Dolby Pro Logic ff
• Dolby Pro Logic II is a new muki-channel
playback format developed
by Dolby Labolatories
using feedback
logic steering technology
and offering improvements
over conventional
Dolby Pro Logic circuits
• Dolby Pro Logic _] can be used to decode
not only sources
recorded
in Dolby Surround
(e)
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 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 _] 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 18)
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) 2-channel Dolby Digital signals
When either of these
signals is input to the AVR-1603,
the surround
mode is automatically
set to Dolby
Pro Logic II when the "DQLBY/DTS
SURROUND"
mode is selected
