Multi Input Setup; Dolby Pro Logic Iix - Rotel RSX-1058 Manuel D'utilisation

NOTE: Default surround modes are stored in-
dependently for the analog and digital inputs
for each source.
Options for the default surround modes are:
Dolby Pro Logic II, Dolby 3 Stereo, DSP 1,
DSP 2, DSP 3, DSP 4, 5ch Stereo, 7ch Ste-
reo, PCM 2 Channel, DTS Neo:6, Bypass
(for analog input only), and Stereo.
NOTE: The following types of digital discs or
source material are generally detected auto-
matically and the proper decoding activated
with no action or setting required: DTS, DTS-ES
Matrix 6.1, DTS-ES Discrete 6.1, Dolby Digital,
Dolby Digital Surround EX, Dolby Digital 2-
channel, PCM 2-Channel, PCM 96kHz, MP3,
HDCD, and HDCD 96kHz.
Since Dolby Digital 5.1 and DTS sources are
detected and decoded automatically, the
default setting typically tells the RSX-1058
how to process a 2-channel stereo signal.
For example, you might have your CD input
default to 2-channel stereo, DVD and VCR
inputs default to Dolby Pro Logic II process-
ing for matrix-encoded Dolby surround ma-
terial, and TUNER input default to one of the
DSP modes.
In some cases, the default setting can be
manually overridden by the front panel sur-
round mode buttons or the SUR+ button
on the remote. See the Manually Selecting
Surround Modes section of this manual for
more information on which settings can be
overridden.
Two of the default surround mode settings
available on this menu offer additional
choices. Dolby Pro Logic II decoding offers
a choice of CINEMA or MUSIC settings, etc.
DTS Neo:6 decoding offers a choice of CIN-
EMA or MUSIC settings. When either Dolby
Pro Logic II or DTS Neo:6 is selected with
this menu item, the current setting choice will
also be displayed. In addition, the function
of the ENTER button changes, taking you to
a sub-menu where you can change the set-
tings and/or additional parameters for Dolby
Pro Logic II or DTS Neo:6 decoding. See the
following section for details.
GROUP DELAY: Also known as "lip-sync"
delay, this setting delays the audio signal for
an input by the specified amount to match
the video input. This feature can be useful
when the video signal is delayed more than
the audio signal as sometimes happens with
39
upconverted digital TV processors or when
trying to match a radio broadcast with the
video from a sports event.
The range of available settings is from 0ms
to 500ms, in 5ms increments. The setting is
individually stored for each input and is the
default group delay each time that input is
selected. The setting can be temporarily over-
ridden from the front panel or the remote.
OPTIONS: This selection is only visible when
Pro Logic II or Neo:6 surround mode is se-
lected. Highlight this line and press ENTER
to go to submenus with additional options;
press the +/- button to select these surround
modes. See below.
To return to the MAIN menu from the INPUT
SETUP menu (except when Dolby Pro Log-
ic II or DTS Neo:6 is selected in the SURR
MODE field), press the ENTER button. Press
the MENU/OSD button on the remote to
cancel the menu display and return to nor-
mal operation.

When the MULTI INPUT source is selected
on the INPUT SETUP menu, the available
options change to reflect the fact that these
inputs are direct analog inputs and bypass
the RSX-1058's digital processing. The INPUT,
CINEMA EQ, DEFAULT MODE and GROUP
DELAY options are not available since these
are all digitally implemented features.
The VID INPUT, INPUT LABEL, INPUT ATT and
12V TRIGGER options are still available and
work as described on the previous menu.
One additional option, LFE REDIRECT, pro-
vides an alternative bass management con-
figuration. Typically, the eight channels of the
MULTI INPUT are configured as pure analog
bypass signals, going straight from the inputs
to the volume control and the preamp outputs,
bypassing all of the digital processing. There
are no crossovers and no bass management;
therefore, whatever signal goes into the sub-
woofer channel will be sent to the subwoofer
preamp output.
This configuration may not be ideal for mul-
tichannel systems configured with high-pass
speakers, redirecting bass to a powered
subwoofer. An option, called LFE REDIRECT,
sends the seven main channels directly to
the outputs as usual. In addition, it takes
a duplicate copy of these seven channels,
combines them into mono, and routes them
through a 100 Hz analog low-pass cross-
over to the subwoofer preamp output. This
creates a summed mono subwoofer signal,
derived from the seven main channels of the
MULTI INPUT.
Use the LFE REDIRECT off for the pure ana-
log bypass configuration. Use the LFE REDI-
RECT on setting to derive the mono summed
subwoofer output.

When Dolby Pro Logic IIx 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 chan-
nels from 2-channel source material.
The first line of the Dolby Pro Logic IIx sub-
menu selects CINEMA, MUSIC, GAME, or
PRO LOGIC modes for matrix decoding.
Use the +/– buttons on the remote to select
a mode.
Select CINEMA to optimize for Dolby Sur-
round encoded movie soundtracks includ-
ing increased surround separation and full-
bandwidth surround channel frequency re-
sponse.
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
