JBL AVR580 Stereo Amplifier User Manual

On the STEREO menu, the choices
made with the
/
Buttons o on
the remote may either turn the surround
processing off for a traditional two-
channel stereo presentation, or select
5 STEREO or 7 STEREO
depend-
ing on whether the 5.1 or 6.1/7.1 output
is in use. The latter modes feed a two-
channel presentation to all speakers,
regardless of the number of speakers in
use. See page 34 for a complete explana-
tion of the 5 Stereo and 7 Stereo modes.
After the selections are made on the
Dolby, DTS, Logic 7, DSP (Surround) or
Stereo menus, press the
/
¤
Buttons
n so that the cursor moves to the
BACK TO MASTER MENU line
and press the
Set Button p.
Speaker Setup
This menu tells the AVR580 which type
of speakers are in use. This is important
as it adjusts the settings that decide
whether your system will use the
“5-channel” or “6-channel/7-channel”
modes, as well as determining which
speakers receive low-frequency (bass)
information.
For each of these settings, use the
LARGE setting if the speakers for a
particular position are traditional full-
range loudspeakers. Use the
SMALL
setting for smaller, frequency-limited
satellite speakers that do not reproduce
sounds below 200Hz. Note that when
“small” speakers are used, a subwoofer
is required to reproduce low-frequency
sounds. Remember that the “large” and
“small” descriptions do not refer to the
actual physical size of the speakers, but
to their ability 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.
This menu screen also allows you to
enter the settings for the AVR580’s Triple
Crossover feature, which allows a differ-
ent crossover point to be used for the
front left/right, center and surround
speakers. In systems where full-range or
tower speakers are used for the front
soundstage or where different models
are in use at the various speaker posi-
tions, this feature allows you to cus-
tomize the bass management and redi-
rection circuits with a precision not previ-
ously possible.
The factory default settings are “small”
for the front left and right, center, and
surround left and right speakers, with a
subwoofer automatically enabled. If your
system includes a 5.1 speaker system
with smaller satellites for all channels
and a subwoofer, then you do not need to
configure your speakers and you may skip
the rest of this section at this time.
It is easiest to enter the proper set-
tings for speaker setup through the
SPEAKER SETUP menu (Figure 5).
If that menu is not already on your screen
from the prior adjustments, press the OSD
Button v to bring up the MASTER
MENU
(Figure 1), and then press the ¤
Button n until the cursor is on the
SPEAKER SETUP line. At this
point, press the
Set Button p to bring
up the SPEAKER SETUP menu
(Figure 5).
Figure 5
The first line of the SPEAKER
SETUP
menu (Figure 5) allows you to
switch the menu to change either the
underlying speaker size setting or the
exact crossover point used for that speaker
group. For the first pass through the
menu, leave the setting at its default
option of
SIZE, and then proceed as
outlined below. Once the speaker choices
have been set, you may wish to return to
this line to change the option so that the
crossover settings may be adjusted.
Begin the speaker setup process by mak-
ing certain that the cursor is pointing
toward the
LEFT/RIGHT line, which
sets the configuration for the front left and
right speakers. If you wish to make a
change to the front speakers’ configura-
tion, press the
/
Buttons o
so that either LARGE or SMALL
appears, matching the appropriate descrip-
tion from the definitions shown above.
When SMALL is selected, low-
frequency sounds will be sent only to the
subwoofer output. If you choose this option
and there is no subwoofer connected,
you
will not hear any low-frequency sounds
from the front channels.
When
LARGE is selected, a full-range
output will be sent to the front left and
front right outputs. Depending on the
choice made in the
SUBWOOFER line
in this menu, bass information may also
be directed to the front left/right speakers,
a subwoofer or both.
NOTE: When the front speakers are set
to the
LARGE option and the surround
mode is set to "Surround Off", or pure two-
channel stereo, when an analog signal
source is present it will be routed directly
from the input to the volume control with-
out being digitized or processed. If you
have full-range front speakers and wish to
remove all digital processing from the cir-
cuit path, select this configuration. If you
wish to set this option for use with only
one input, such as a CD player that uses
an external DAC or an optional, external
phono preamp, you may also wish to
choose the
INDEPENDENT setting
on the
BASS MGR line at the bottom
of this menu so that only those inputs
where the analog bypass is desired will be
routed in this fashion, while other analog
inputs such as a VCR or cable box will be
digitized for surround processing.
When you have completed your selection
for the front channel, press the
¤
Button
n on the remote to move the cursor to
CENTER.
Press the
/
Buttons o on
the remote
to select the option that best
describes your system, based on the speaker
definitions shown below.
When
SMALL is selected, low-frequency
center channel sounds will be sent only to
the subwoofer output. If you choose this
option and there is no subwoofer con-
nected, you will not hear low-frequency
sounds from the center channel.
When
LARGE is selected, a full-range
output will be sent to the center speaker
output, and NO center channel signal will
be sent to the subwoofer output.
NOTE: If you choose Logic 7 as the sur-
round mode for the particular input
source for which you are configuring your
speakers, the AVR580 will not make the
“large” option available for the center
speaker. This is due to the requirements
of Logic 7 processing, and does not indi-
cate a problem with your receiver.
