The SPEAKER SETUP menu is used to config-
ure the RSP-1066 for use with your specific
loudspeakers. The menu is accessed from the
MAIN menu.
Home theater systems vary in the number of
speakers and the bass capabilities of those
speakers. The RSP-1066 offers surround modes
tailored to systems with various numbers of
speakers and bass management features which
send bass information to the speaker(s) best
able to handle it – subwoofers and/or large
speakers. For optimum performance, you must
tell the RSP-1066 the number of speakers in
your system and how bass should be distrib-
uted among them.
: There are two types of bass in a sur-
NOTE
round sound system. The first is normal bass
recorded in each of the main channels (front,
center, and surround). This bass is present in
all recordings and soundtracks. In addition,
Dolby Digital 5.1 and DTS 5.1 recordings
have a Low Frequency Effects (LFE) channel –
the .1 channel. This bass channel, typically
played by a subwoofer, is used for effects
such as explosions or rumble. The use of the
LFE channel will vary from soundtrack to
soundtrack. Recordings that are not encoded
in Dolby Digital or DTS do not have the LFE
channel.
The following configuration instructions refer
to LARGE and SMALL speakers, referring more
to their desired bass configuration than their
physical size. Specifically, use the LARGE
setting for speakers that you want to play deep
bass signals. Use the SMALL designation for
speakers that would benefit from having their
bass sent to more capable speakers. The bass
management system redirects bass informa-
tion away from all SMALL speakers and sends
it to the LARGE speakers and/or the SUB-
WOOFER.

Four examples illustrate the principles behind
bass management:
• A system with five LARGE speakers and a
subwoofer: This system requires no bass
redirection. All five speakers play the nor-
mal bass recorded in their respective chan-
nels. The subwoofer plays only the LFE
channel bass. This may not be the most ef-
ficient use of system resources. Depend-
ing on the soundtrack, there may be mini-
mal use of the LFE channel, so the subwoofer
would be underutilized. Meanwhile the
normal bass places higher demands on the
capabilities of the other speakers and the
amplifiers driving them.
• A system with LARGE front, center, and
surround speakers, but no subwoofer. The
normal bass from the front, center, and
surround channels is played in its respec-
tive speakers. With no subwoofer, the LFE
bass is redirected to all five LARGE speak-
ers. This places significant demands on these
speakers and their amplifiers, as they must
play their own normal bass plus the very
demanding LFE bass.
• A system with LARGE front speakers, SMALL
center and surround speakers, and a sub-
woofer. The normal bass from the SMALL
center and surround speakers is redirected
to the LARGE front speakers and the sub-
woofer. The LARGE front speakers play their
own normal bass plus the redirected bass
from the SMALL speakers. The subwoofer
plays the LFE bass plus some of the redi-
rected bass from the SMALL center and
surround channels. This might be an ap-
propriate configuration with a pair of very
capable front speakers driven by a large
separate power amplifier.
• A system with all SMALL speakers and a
subwoofer. The normal bass from all chan-
nels is redirected to the subwoofer, which
also plays the LFE bass. The subwoofer
handles ALL of the bass in the system, while
the other speakers benefit from the added
dynamic range and reduced strain of not
having to play low bass. This configura-
tion realizes the full benefits of bi-amping:
bass is played by the speaker most suited
to do so, the other speakers play louder
with less distortion, and the need for am-
plifier power is reduced. This is the most
popular home theater configuration and
should be strongly considered even if the
speakers are physically large and capable
of playing low bass. This configuration is
particularly advantageous when driving the
speakers with moderate power amplifiers.
: An alternative configuration for setting
NOTE
up a satellite/subwoofer package as the front
speakers: follow the speaker manufacturer's
instructions, connecting the high-level inputs
of the powered subwoofer directly to the
speaker outputs of front amplifier and con-
necting the satellite speakers to the
subwoofer's own crossover. In this arrange-
ment, the speakers would be classified as
LARGE and the subwoofer setting would be
OFF for all surround modes. No information
will be lost during playback because the sys-
tem knows to redirect the bass information to
the front LARGE speakers. While this configu-
ration may ensure correct satellite speaker
operation by using the speaker manufacturer's
own crossovers, it has some disadvantages
in terms of system calibration.
The following speaker options are available:
FRONT SPEAKERS (small/large): This
menu setting determines what kind of main front
left and right speakers you are using. Use the
LARGE setting to have the front speakers play
low bass. Use the SMALL setting to redirect
normal bass away from these speakers to a
subwoofer.
CENTER SPEAKER(S) (small/large/
none): Use the LARGE position (not available
with SMALL front speakers) to have the cen-
ter speaker play low bass. Use the SMALL po-
sition if your center channel speaker has more
limited low frequency capability, or if you prefer
that the bass be sent to the subwoofer. 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 (small/large/
none): Select the LARGE setting (not avail-
able with SMALL front speakers) to have the
surround speakers play low bass. If your rear
speakers have limited bass capability or if you
would prefer that the bass go to a subwoofer,
use the SMALL setting. 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).
