tion. Thus, these discs must be decoded by
a SACD compatible player, with the output
sent to the RSX-1058's MULTI INPUTS.
MP3: The RSX-1058 also features a decoder
for the digital MP3 (MPEG1- Audio Layer 3)
compression format. MP3 format recordings
are available on the Internet and can be played
on portable MP3 players or some disc play-
ers that can read CD-ROM discs connected
to the RSX-1058's digital inputs.
MPEG Multichannel: Widely used in Eu-
rope, this format uses MPEG data compres-
sion to record up to 5.1 channels of discrete
digital audio, similar in function to the Dolby
Digital and DTS formats.

Automatic Surround Modes

Decoding of digital sources connected to the
digital inputs is generally automatic, with de-
tection triggered by a "flag" embedded in the
digital recording telling the RSX-1058 what
decoding format is required. For example,
when Dolby Digital 5.1 or DTS 5.1 channel
surround is detected, the RSX-1058 activates
the proper decoding.
The unit will also detect DTS-ES Matrix 6.1
or DTS-ES Discrete 6.1 discs and activate
DTS-ES Extended Surround decoding. Dol-
®
by Digital Surround EX recordings also trig-
ger automatic decoding (although not all
Surround EX DVDs have the necessary flag
and may require manually activating Sur-
round EX decoding).
Likewise, a digital input from an HDCD
coded compact disc, a standard CD, a DTS
96/24 disc, or MP3 player will be auto-de-
tected and properly decoded to 2CH stereo
operation.
Dolby Pro Logic IIx or Rotel XS processing
can be configured to be automatically active
in all 6.1 or 7.1 channel systems configured
with 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 ex-
tended surround mode.
In many cases, the RSX-1058 will also rec-
ognize a digital signal with Dolby Surround
encoding (such as the default soundtrack on
many DVDs) and activate Dolby
decoding. Additionally, you can configure a
default surround mode for each input using
the INPUT SETUP menu (see the Setup sec-
tion of this manual).
Combined with the auto-detection of Dolby
Digital 5.1 and DTS, this default surround
setting makes operation of the RSX-1058 sur-
round modes totally automatic. For example,
if you set Dolby Pro Logic II movie mode as
the default for all of your video inputs, the
RSX-1058 will automatically decode Dolby
Digital 5.1 and DTS soundtracks when they
are played and use Pro Logic II matrix de-
coding 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 mu-
sic mode if you prefer to hear music sources
in surround sound.
NOTE: A digital signal coming into the RSX-1058
will be recognized and properly decoded. How-
ever, on a DVD with multiple soundtracks, you
must tell the DVD player which one to send to
the RSX-1058. 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 com-
bination of auto-detection of Dolby Digital
and DTS recordings and setting default sur-
round modes for each input during the setup
en- of the RSX-1058 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 set-
ting 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 speak-
ers only) with no surround processing.
Pro Logic II • Downmixed 2-channel playback of Dolby
® ®
Digital 5.1 or DTS recordings.
• Dolby 3-channel stereo (left/right/center)
of 2-channel recordings.
30
• 5-channel or 7-channel stereo from 2-
channel recordings.
• One of four DSP modes for DSP concert
hall simulation from 2-channel music re-
cordings.
• Dolby Pro Logic II cinema or music mode
matrix decoding of 2-channel record-
ings.
• 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, Dolby Digital, MP3, MPEG Mul-
tichannel, HDCD (96kHz), and PCM 2-channel
(96kHz) 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 re-
cordings for 2-channel playback.
• HDCD (non 96kHz) and PCM 2-channel
(non 96kHz) digital signals can be over-
ridden to Dolby Pro Logic II, Dolby 3-Ste-
reo, 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
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 6.1ch or 7.1ch system, you
can also choose Dolby Surround EX, Dolby
Pro Logic IIx Music, Dolby Pro Logic IIx Cin-
ema (7.1ch 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.
