3.0
This indicates a three-channel signal, which normally will be reproduced
through the left front, center, and right front output channels. If the system
contains no center speaker, the center channel signal will be split equally
between the left and right front output channels.
4.0
This indicates a four-channel signal, reproduced through the left and right
front and surround output channels.
5.0
This indicates a five-channel signal, which normally is reproduced through
the left and right front, center, and left and right surround channels.
.1
The ".1" indicates that the bitstream contains a low-frequency effects (LFE)
channel, which carries only bass information. In most systems, the LFE
channel is reproduced by a subwoofer. If there is no subwoofer, it will be
routed to speakers designated as Large.
The number of channels indicated on the front-panel display is based on the
number of channels of information present in the digital bitstream. It is not an
indication of a signal being present on a particular speaker and does not
reflect your system’s speaker configuration. For example, if you have set
"Center Speaker" and "Subwoofer" to "None" (not present) in the Speaker
Configuration Menu, the display will still show Dolby Digital 5.1 for a 5.1-chan-
nel Dolby Digital soundtrack.
When a Dolby Digital soundtrack contains surround back channel information,
the front-panel display will indicate THX Surround EX.
THX Surround EX will NOT be displayed if any of the following conditions
exist:
1. The Surround Back channels in the Speaker Configuration Menu are set
to None
2. THX Surround EX is turned to OFF in the THX Setup Menu
3. The soundtrack is flagged as not containing stereo surround information
THX Surround EX-encoded discs can be played on a system with any number
of speakers connected to it, but to take full advantage of the surround back
channel information a full complement of speakers must be connected, includ-
ing the Surround Back speakers.
When a DTS soundtrack contains surround back channel information, the
front-panel display will indicate DTS ES Matrix or DTS ES Discrete.
DTS ES soundtracks containing 6.1 channels of information are encoded in a
matrixed or discrete format. In a DTS ES Matrix soundtrack, the surround
back channel information is encoded into the primary surround channels,
extracted by the DSP module, and then sent to the Surround Back output
channels. DTS ES Discrete soundtracks contain a discrete surround back
channel signal, which is decoded by the DSP module and fed to the Surround
Back outputs.
The Stage One will not decode DTS ES if the Surround Back channels are set
to "None" in the Speaker Configuration Menu. DTS ES-encoded discs are
backward-compatible with a 5.1 system, so Surround Back channels are not
required to play them. However, the system cannot take advantage of the
extra surround channel unless, in addition to the primary surround speakers,
surround back speakers are connected.
2-Channel and 8-Channel Analog Passthrough
The top line of the display will indicate when the 8-Channel Analog input or
the Stereo Direct (2-channel passthrough) mode is selected.
Sampling Rate
For PCM signals (standard uncompressed digital output from a CD, DVD, or
laserdisc player or a digital satellite receiver), the display will show the sam-
pling frequency to the right of the post-processing mode.
Volume Level
The bottom right-hand corner of the display indicates the current master vol-
ume setting. The master volume ranges from –62dB to + 12dB, with 00dB as
the THX reference setting.
Current Input
The bottom left-hand side of the display indicates the currently selected input,
as long as there is no post processing information required to be displayed.
When the tuner is selected, this location will display the currently tuned radio
frequency.
Post-Processing
In some modes, the Stage One may need to display additional information,
such as the type of post-processing being applied. The following list presents
the Stage One modes and the post-processing or additional information avail-
able in each.
Dolby Pro Logic II
has five possible decoding modes, selected from the
remote control’s Pro Logic II Modes page: Movie, Music, Panorama (indi-
cated as PAN), Matrix and Pro Logic. (See "Modes.")
Dolby Digital
has 11 possible decoding modes, either selected from the
remote control’s Modes page or loaded as the default based on system set-
tings: PLII, Stereo, Mono, 5-Channel Stereo, Club, Party, DTS Neo:6, THX,
THX Surround EX, THX MusicMode, and THX Ultra2 Cine. Certain modes
may only be applied to Dolby Digital 2.0 signals that are not flagged as sur-
round encoded (See "Modes.")
DTS
has 10 possible decoding modes, selected from the remote control’s
Modes page or loaded as the default based on system settings: PLII,
Stereo, Mono, 5-Channel Stereo, Club, Party, DTS Neo:6, THX, THX
MusicMode, and THX Ultra2 Cine. Certain modes may only be applied to
DTS 2.0 signals that are not flagged as surround encoded (See "Modes.")
