14 SYSTEM CONFIGURATION
System Configuration
Once the speakers have been placed in the
room and connected, the remaining steps are to
program the system configuration memories.
With the AVR 1550 two kind of memories are
used, those associated individually with the
input selected, e.g. surround modes, and others
working independently from any input selected
like speaker output levels, or delay times used
by the surround sound processor.
First Turn On
You are now ready to power up the AVR 1550 to
begin these final adjustments.
1. Plug the Power Cable
G
into an un-
switched AC outlet.
2. Press the Main Power Switch
1
in until it
latches and the word “OFF” on the top of the
switch disappears inside the front panel. Note
that the Power Indicator
3
will turn orange,
indicating that the unit is in the Standby mode.
3. Remove the protective plastic film from the
front-panel lens. If left in place, the film may
affect the performance of your remote control.
4. Install the three supplied AAA batteries in the
remote as shown. Be certain to follow the (+)
and (–) polarity indicators that are on the
bottom of the battery compartment.
5.Turn the AVR 1550 on either by pressing the
System Power Control
2
or the Input
Source Selector
!
on the front panel, or via
the remote by pressing the AVR Selector
5
or any of the Input Selectors
46
on the
remote. The Power Indicator
3
will turn green
to confirm that the unit is on, and the Main
Information Display
*
will also light up.
Settings to be Made With Each
Input Used
The AVR 1550 features an advanced memory
system that enables you to establish different
settings for the speaker configuration, digital
input and surround mode for each input source.
This flexibility enables you to custom tailor the
way in which you listen to each source and have
the AVR 1550 memorize them. This means, for
example, that you may associate different sur-
round modes and analog or digital inputs with
different sources, or set different speaker config-
urations with the resultant changes to the bass
management system or the use of the Center
speaker. Once these settings are made, they will
automatically be recalled whenever you select
an input.
The default settings for the AVR 1550, as it is
shipped from the factory, have all inputs set for
an analog source (except for the DVD input,
which has the Coaxial Digital Input 1
9
as
the default), with stereo as the surround mode,
the front left and right speakers set to “large”
(with surround modes other speakers to
”small”), and a subwoofer connected. Before
using the unit, you will probably want to change
these settings for most inputs so that they are
properly configured to reflect the use of digital
or analog inputs, the type of speakers installed
and the surround mode associated with the
input. Remember, since the AVR 1550’s memory
system keeps the settings for each input sepa-
rate from the other inputs, you will need to make
these adjustments for each input used. However,
once they are made, further adjustment is only
required when system components are changed.
To make this process as quick and as easy as
possible, we suggest that with each of these set-
tings to be made you step through each input.
Once you have completed the settings for the
first input, many settings may be duplicated for
the remaining inputs.
The items that follow will describe the individual
settings required for each input.
Input Setup
The first step in configuring the AVR 1550 is to
select an input.This may be done by pressing
the front panel Input Source Selector
!
until the desired input’s name appears momen-
tarily in the Main Information Display
M
.
The input may also be selected by pressing
the appropriate Input Selector on the
remote control
46
.
The second step is to associate one of the digital
inputs with the selected input source (if this is
needed, otherwise the selected analog input will
remain). Press the Digital Input Select button
Ô
F
on the front panel or the remote. Within
five seconds, make your input selection using the
Selector buttons on the front panel
&
or the
⁄/¤ buttons
C
on the remote until the
desired digital or analog input is shown in the
Main Information Display
M
. Then press the
Enter button
E
to enter the new digital input
assignment.
After the setting has been made with one input,
repeat as described above with all inputs in use.
The digital input associated with the input
selected can also be changed at any time later
and the AVR 1550´s memory system will keep
the settings until they are changed again.
Speaker Setup
This setup tells the AVR 1550 which type of
speakers are in use.This is important as it
adjusts the settings that determine which
speakers receive low frequency (bass) informa-
tion and whether a Center speaker should be
used or not, separately for each input used.
For each of these settings use the LARGE
setting if the speakers for a particular position
are traditional full-range loudspeakers that are
capable of reproducing sounds below 100Hz.
Use the SMALLsetting for smaller,
frequency-limited satellite speakers that do not
reproduce sounds below 100Hz. Note that
when “small” front (left and right) speakers are
used, a subwoofer is required to reproduce low
frequency sounds. If you are in doubt as to
which category describes your speakers, consult
the specifications in the speakers’ owner’s
manual, or ask your dealer. Remember that each
speaker setup that differs from the default
settings (see above) must be made individually
for each input in use.
It is best to select the Dolby Pro Logic II Movie
mode for speaker setup.Then with the currently
selected input all speaker settings will be copied
to other surround modes too (as far as possible)
and need not be repeated with any other mode.
