is played by the speaker most suited to do so, the main speakers may
play louder with less distortion, and the need for amplifier power is
reduced. This configuration should be used with bookshelf-size or
smaller main speakers. It should also be considered in some cases
with floorstanding front speakers. This configuration is advantageous
when driving the system with moderate power amplifiers.

LARGE front speakers, SMALL other speakers, and a subwoofer: The
normal bass from the SMALL center and surround speakers is redirected
to the LARGE front speakers and the subwoofer. The LARGE front
speakers play their own normal bass plus the redirected bass from
the SMALL speakers. The subwoofer plays the redirected bass from
all of the other channels. This might be an appropriate configuration
with a pair of very capable front speakers. A potential disadvantage
with mixed LARGE and SMALL configurations is that the bass response
may not be as consistent from channel to channel as it might be with
the all SMALL configuration.

The SPEAKER CONFIGURATION menu is used to configure the RAP-1580 for
use with your specific loudspeakers and to determine the bass management
configuration as described in the previous overview. The menu is accessed
from the MAIN menu. The Audio Configuration will determine which speakers
are displayed in the Speaker Configuration menu.
The following speaker options are available:
FRONT SPEAKERS (Small/Large): Use the "Large" setting to have the front
speakers play low bass (full-range). Use the "Small" setting to redirect
normal bass away from these speakers to a subwoofer (high-pass filtered).
CENTER SPEAKER(S) (Large/Small/None): Select the "Large" setting (not
available with SMALL front speakers) to have the center speaker play low
bass (full-range). Select the "Small" setting if your center channel speaker
has limited low frequency capability, or if you prefer that the bass be sent
to the subwoofer (high-pass). Select the "None" setting if your system does
not have a center channel speaker (the surround modes will automatically
divide all center channel information equally between the two front speakers,
creating a phantom center channel).
SURROUND SPEAKERS (Large/Small/None): Select the "Large" setting (not
available with SMALL front speakers) to have the surround speakers play
low bass (full-range). If your rear speakers have limited bass capability
or if you would prefer that the bass go to a subwoofer, select the "Small"
setting (high-pass). If your system has no rear surround speakers, select the
"None" setting (surround channels are added to the front speakers so none
of the recording is lost).
SUBWOOFER (Yes/Max/No): The "Yes" setting is the standard setting if your
system has a subwoofer. If your system does not have a subwoofer, select

"No". Select the "Max" setting for maximum bass output with normal bass
being duplicated by both the subwoofer and any LARGE speaker in the system.
CENTER BACK (1Large/1Small/2Large/2Small/None): Some systems have
one or two additional center back surround speakers. Select the "Large"
setting (not available with SMALL front and surround speakers) to have
your center back speaker(s) play low bass. Use "1Large" if you have one
center back speaker (6.1) or "2Large" (7.1) if you have two center back
speakers (7.1). If your center back speakers have limited bass capability or
if you would prefer that the bass go to a subwoofer, use the "Small" setting
("1Small" for one speaker, "2Small" for two speakers). If your system has
no center back speakers, select the "None" setting.
CEILING FRONT (Large/Small/None): Select the "Large" setting (not available
with SMALL front and surround speakers ) to have your top front speakers
play low bass. If you would prefer that the bass go to a subwoofer, use
the "Small" setting.
CEILING REAR (Large/Small/None): Select the "Large" setting (not available
with SMALL front , top front and surround speakers ) to have your top rear
speakers play low bass. If you would prefer that the bass go to a subwoofer,
use the "Small" setting.
ADVANCED: Speaker configuration is generally a global setting for all surround
modes and need only be done once. However, for special circumstances,
the processor provides the option of setting the speaker configuration
independently for each surround mode. Select the ADVANCED SETUP line
on the menu and press ENTER to go to the ADVANCED SPEAKER SETUP
menu described in the following section.
To change a setting on the SPEAKER CONFIGURATION menu, place the
highlight on the desired line using the Up/Down arrow buttons and use the
Left/Right arrow buttons to toggle through the available settings. To return to
the MAIN menu, select "BACK" on the OSD and press the ENTER button,
or press the BACK button. Press the SETUP/MENU button, or select "EXIT"
on the OSD to exit setup and return to normal operation.

In most cases, the standard speaker configuration described above is a global
setting and can be used for all surround modes. However, the processor
provides the capability to customize these settings for three different modes:
Dolby, DTS, and Stereo. In addition, the ADVANCED SPEAKER SETUP
allows you to select a customized high-pass crossover frequency for the
front, center, surround, surround back speakers.
NOTE: In most systems, the default settings on this menu will provide
the most predictable results and most users will not need to change
any settings. You should fully understand bass management and have
a specific reason for needing a custom configuration before changing
these settings. Otherwise, skip to the following topic, SUBWOOFER
