want the particular speaker to play the deep
bass or whether you would prefer that the deep
bass be sent to the subwoofer. If you have
invested in a subwoofer for your system, you
might decide to send all of the bass to it, re-
gardless of how capable the other speakers
in the system may be. In this case, you would
tell the RSP-985 that all of your speakers are
SMALL, without regard to how big they may
actually be.
An alternative configuration for setting up front
SMALL speakers with a subwoofer would be
to follow the speaker manufacturer’s instruc-
tions, wiring the SMALL speakers to the
subwoofer’s crossover and then connecting the
subwoofer directly to the front speaker con-
nection terminals. In this arrangement, 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 system knows
to redirect the bass information to the front
LARGE speakers. This configuration may be
optimal for many users as it can improve the
way the bass integrates into the listening room
and ensure correct satellite speaker operation
by using the speaker manufacturer’s own cross-
overs.
To configure your system, highlight each of the
following menu lines and use the VOLUME
DOWN/UP buttons to make the setting that
best matches your speakers.
MAIN (Small/Large): This menu setting tells
the RSP-985 what kind of main front left and
right speakers you are using. Use the LARGE
setting if your main left and right speakers are
full range designs with good bass response
capability. If you are using satellite mini-speakers
or if you have THX certified front speakers,
choose the SMALL setting to redirect LFE bass
frequencies to the subwoofer. Highlight this
menu line and use the VOLUME DOWN/UP
buttons to make the appropriate setting. If you
have THX certified front speakers, choose the
SMALL setting.
CENTER (small/large/none): Surround
sound derives much of its spatial accuracy from
a center channel speaker located very close
to a TV. This center channel speaker anchors
dialog information to your screen for greater
coherence between the apparent point of origin
for picture and sound.
• Use the LARGE position if your
system’s center channel speaker is
capable of full-range, extended
bass response. In this position, bass fre-
quencies are handled by the center chan-
nel speaker itself.
• Use the SMALL position if your cen-
ter channel speaker has more lim-
ited low frequency capability or if
you have a THX certified center
channel speaker. Low frequencies be-
low 80 Hz are redirected to the front left
and front right speakers (or to a subwoofer)
so they will not overload the center chan-
nel speaker. When no subwoofer is used,
all bass frequencies below 80 Hz are sent
to the front left and right speakers. When
a subwoofer is used, bass below 80 Hz
is automatically sent to the subwoofer.
• Select the NONE setting if your sys-
tem does not have a center chan-
nel speaker. The RSP-985 turns the center
channel output off and divides the center
channel signal equally between left and
right front speakers.
SURROUNDS (small/large/none): Sur-
round speaker performance varies widely from
system to system. It is important to tell the
RSP-985 what type of surround speakers you
have in your system.
• If your rear surround speakers are
capable of sustained low frequency
output below 80 Hz, select the
LARGE setting. This ensures that your rear
speakers receive a full bandwidth signal
whenever available from the RSP-985.
• If your rear speakers have limited
bass capability or if you have THX
certified surround speakers, use the
SMALL setting. This limits the RSP-985’s
low frequency output so that the speaker
is not overdriven. The result will be cleaner
reproduction of ambience and effects in-
formation. In the SMALL position, the bass
information originally intended for particular
speakers is sent to the Subwoofer or LARGE
speakers instead. Fundamental tones are
not lost but simply redirected to the speakers
best able to handle them.
• If your system has no rear surround
speakers, select the NONE setting.
Surround information is sent to the front
speakers and, in certain cases, the
subwoofer.
SUBWOOFER (On/Off): Use the ON set-
ting if your system has a subwoofer. This ac-
tivates the built-in electronic crossover to route
low frequencies (called “redirected bass”) from
any SMALL speakers to the subwoofer, which
is best capable of reproducing these low fre-
quency signals. If your system does not
have a subwoofer, put this switch in
the OFF position. This sends the redirected
bass signals plus the LFE channel (Low Fre-
quency Extension, the .1 channel) to LARGE
speakers in the system.
NOTE : In STEREO, DOLBY PRO LOGIC, and
DSP MUSIC modes, bass is directed to the
front speakers and NOT to the subwoofer
when LARGE is selected. For subwoofer out-
put in these modes with LARGE front speak-
ers, override the bass management system
with a setting in the SUBWOOFER SETUP
menu.
Once you have completed the settings for all
of your speakers, return to the MAIN menu
by pressing the BACK button.
