34 RSP-1098 Surround Sound Processor
Dolby Pro Logic II
DOLBY PRO LOGIC II
MODE:Music
OPTIONAL PARAMETERS
PANORAMA:Off
DIMENSION:3
CENTER WIDTH:0
INPUT SETUP MENU
When Dolby Pro Logic II is selected as the
default surround mode on the INPUT SETUP
menu, there are additional settings and pa-
rameters to optimize the surround decoding
for music or movie soundtracks. Dolby Pro Logic
II uses matrix decoding algorithms to derive
a center channel and surround channels from
2-channel source material.
The first line of the Dolby Pro Logic II sub-menu
selects one of three types of matrix decoding:
CINEMA, MUSIC, or EMULATION modes. Use
the +/– buttons on the remote to select a mode.
Select CINEMA to optimize for Dolby Surround
encoded movie soundtracks including in-
creased surround separation and full-bandwidth
surround channel frequency response.
Select EMULATION for decoding that emu-
lates the original Dolby Pro Logic system. You
may prefer this option for older soundtracks
that are not of optimum audio quality. EMU-
LATION mode reduces the high-frequency
response and separation of the surround chan-
nels and may increase the delay setting.
Select MUSIC to optimize for musical record-
ings. When the MUSIC mode is selected, three
additional parameters will be available on the
OSD screen. Use the UP/DOWN buttons on
the remote to select a parameter. Use the +/–
buttons to change the selected parameter as
follows:
• PANORAMA: The Panorama option
extends the front stereo image to include
the surround speakers for a dramatic “wrap-
around” effect. The options are OFF or ON.
• DIMENSION: The Dimension option al-
lows you to gradually adjust the soundfield
towards the front or towards the rear. There
are seven incremental settings from 0 to
6. A setting of 0 shifts the soundfield to-
wards the rear for maximum surround ef-
fect. A setting of 6 shifts the soundfield to
the front for minimum surround effect. The
default setting of 3 provides a “neutral”
balance between the two extremes.
• CENTER WIDTH: The Center Width option
allows you to spread the signal intended for
the center speaker to the left and right front
speakers, widening the perceived soundfield.
There are eight incremental settings from 0
to 7. With the default setting of 0, there is
no center width spreading and all of the center
channel information is sent to the center
speaker. The maximum setting of 7 shifts all
of the center channel signal to the left and
right speakers, essentially muting the center
speaker and maximizing the soundfield width.
Other settings provide incremental steps be-
tween the two extremes.
When you have completed all the desired
adjustments, highlight the INPUT SETUP MENU
line at the bottom of the screen and press the
ENTER button to return to the INPUT SETUP
menu (or just press the ENTER button).
DTS Neo:6
DTS Neo:6
MODE:Cinema
INPUT SETUP MENU
When DTS Neo:6 is selected as the default
surround mode on the INPUT SETUP menu,
there are additional option settings and pa-
rameters available to optimize the surround
decoding for various types of recordings, music
or movie soundtracks. DTS Neo:6 uses ma-
trix decoding algorithms to derive a center
channel and surround channels from 2-chan-
nel source material.
In DTS Neo:6 surround mode, there will only
be one choice available on the sub-menu:
selecting CINEMA or MUSIC modes. Use the
+/– buttons on the remote to change the set-
tings.
• Select CINEMA to optimize the DTS Neo:6
decoding for movie soundtracks.
• Select MUSIC to optimize the DTS Neo:6
decoding for musical recordings.
When you have completed the setting, high-
light the INPUT SETUP MENU line at the bot-
tom of the screen and press the ENTER but-
ton to return to the INPUT SETUP menu (or just
press the ENTER button).
Configuring
Speakers and Audio
This section of the setup process covers items
concerning audio reproduction such as the
number of speakers, bass management includ-
ing subwoofer crossovers, establishing equal
output levels for all channels, delay settings,
and tone contour settings.
Understanding Speaker
Configuration
Home theater systems vary in the number of
speakers and the bass capabilities of those
speakers. The RSP-1098 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-1098 the number of speakers in
your system and how bass should be distrib-
uted among them.
NOTE : There are two types of bass in a sur-
round system. The first is bass recorded in each
of the main channels (front, center, and sur-
round). This bass is present in all recordings
and soundtracks. In addition, Dolby Digital 5.1
and DTS 5.1 recordings may have a Low Fre-
quency Effects (LFE) channel – the .1 channel.
This LFE channel, typically played by a sub-
woofer, 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 set-
ting 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 information
away from all SMALL speakers and sends it to
the LARGE speakers and/or the SUBWOOFER.
It may be useful to think of LARGE as “full-range”
and SMALL as “high-pass filtered.”
Four typical examples of the many possible
system configurations illustrate the principles
behind bass management:
