32 33 English RSP-1570 Surround Sound Processor 32 33 English RSP-1570 Surround Sound Processor
center back speaker(s) and will ensure proper extended surround
decoding of all multichannel digital signals, even those that might not
otherwise trigger the proper extended surround mode.
In many cases, the processor will also recognize a digital signal with Dolby
Surround encoding (such as the default soundtrack on many DVDs) and
activate Dolby
® Pro Logic II ® decoding. Additionally, you can configure a
default surround mode for each input using the INPUT SETUP menu (see
the Setup section of this manual).
Combined with the auto-detection of Dolby Digital 5.1 and DTS, this
default surround setting makes operation of the processor’s surround
modes totally automatic. For example, if you set Dolby Pro Logic II
movie mode as the default for all of your video inputs, the processor will
automatically decode Dolby Digital 5.1 and DTS soundtracks when they
are played and use Pro Logic II matrix decoding for all other recordings.
For stereo inputs such as CD and Tuner, you could select STEREO mode
as the default for 2-channel playback or Dolby Pro Logic II music mode if
you prefer to hear music sources in surround sound.
Note: A digital signal coming into the processor will be
recognized and properly decoded. However, on a DVD with
multiple soundtracks, you must tell the DVD player which one
to send to the processor. For example, you may need to use
the DVD’s menu system to select the Dolby Digital 5.1 or DTS
5.1 soundtrack rather than the default Dolby Digital 2.0 Dolby
Surround soundtrack.
Manually Selecting
Surround Modes
As described in the previous section, the combination of auto-detection
of Dolby Digital and DTS recordings and setting default surround
modes for each input during the setup of the processor makes operation
of surround modes totally automatic. For many users, this automatic
surround mode selection will meet all of their listening needs.
For users who prefer a more active role in setting surround modes,
buttons on the remote and the front panel provide manual selection of
surround mode that are not automatically detected or, in some cases, to
override an automatic setting.
Manual settings available from the front panel and/or the remote might
be used when you want to play:
• Standard 2-channel stereo (left/right speakers only) with no surround
processing.
• Downmixed 2-channel playback of Dolby Digital 5.1 or DTS
recordings.
• Dolby 3-channel stereo (left/right/center) of 2-channel recordings.
• 5-channel or 7-channel stereo from 2-channel recordings.
• One of four DSP modes for DSP concert hall simulation from 2-
channel music recordings.
• Dolby Pro Logic II cinema or music mode matrix decoding of 2-
channel recordings.
• DTS Neo:6 cinema or music mode matrix decoding of 2-channel
recordings.
• Dolby Digital Surround EX decoding of Dolby Digital 5.1 channel
recordings or Dolby Digital Surround EX discs that do not trigger
automatic decoding.
Note: DTS, DTS-ES Matrix 6.1, DTS-ES Discrete 6.1, DTS 96/24,
DTS-ES 96/24 and Dolby Digital signals are auto-detected and
cannot be overridden. However, you can choose to use Dolby
Digital Surround EX decoding for any Dolby Digital 5.1 source
material. You can also downmix Dolby Digital 5.1 or DTS 5.1
recordings for 2-channel playback.
• PCM 2-channel (non 96kHz) digital signals can be overridden to
Dolby Pro Logic II, Dolby 3-Stereo, DTS Neo:6, DSP 1–4, 5CH
Stereo, 7CH Stereo, and Stereo.
• Dolby Digital 2-channel Stereo can be overridden to Dolby Pro Logic
II, Dolby 3-Stereo, and Stereo.
The following topics describe in detail the manual surround mode options
available for each type of recording:
Dolby Digital 5.1 discs
Dolby Digital Surround EX discs
7LNO
Dolby Digital decoding is auto-detected and cannot be overridden. You
may, however, select a 2-channel downmix of 5.1 channel recordings.
In a 6.1 or 7.1 channel system, you can also choose Dolby Surround
EX, Dolby Pro Logic IIx Music, Dolby Pro Logic IIx Cinema (7.1 channel
only), or Rotel XS processing for center back channels.
Note: In addition to the options that follow, you can press the
2CH button on the front panel or the remote to toggle between 2-
channel downmix and multichannel playback.
• On a 5.1 system. Press the SUR+ button on the remote, then press
the +/– buttons to change between DD 5.1 channel or DD 2.0
channel downmix playback.
• On a 6.1 system. Press the SUR+ button on the remote, then use the
+/– buttons to step through five options: DD 2.0 channel downmix,
DD 5.1 channel, DD Surround EX center back processing, DD with
Pro Logic IIx Music center back processing or DD with Rotel XS center
back processing. You should typically select Surround EX or discs that
are labeled Dolby Digital Surround EX. For standard 5.1 channel
discs, Dolby Pro Logic IIx Music or Rotel XS processing will provide
a more diffuse surround effect than the more highly localized Dolby
EX decoding and will probably be the better 6.1 channel options
for non-Surround EX discs. Selecting DD 5.1 forces the center back
channel processing off for conventional 5.1 channel playback. You
can also repeatedly press the DOLBY PLIIx Mode button on the front
panel until the desired center back channel option is selected.
• On a 7.1 system. Press the SUR+ button on the remote, then use the
+/– buttons to step through six options: DD 2.0 channel downmix,
DD 5.1 channel, DD Surround EX center back processing, DD with
Pro Logic IIx Music center back processing, DD with Pro Logic IIx
Cinema back channel processing, or DD with Rotel XS center back
processing. You should typically select Surround EX or discs that
are labeled Dolby Digital Surround EX. For standard 5.1 channel
discs, Dolby Pro Logic IIx Music or Rotel XS processing will provide a
more diffused surround effect than the more highly localized Dolby
EX decoding and may be the better 7.1 channel options for non-
Surround EX discs. Selecting DD 5.1 forces the center back channel
processing off for conventional 5.1 channel playback. You can also
repeatedly press the DOLBY PLIIx Mode button on the front panel until
the desired center back channel option is selected.
Note: When playing any Dolby Digital source, you can select
one of three dynamic range control settings. See the Dynamic
Range topic in the Other Settings section of this manual.
