The second number indicates whether any surround channels are
“0” indicates that no surround information is present.
“1” indicates that a matrixed surround signal is present.
“2” indicates discrete left and right surround channels.
“3” is used with DTS-ES bitstreams to represent the presence
of the discrete surround back channel, in addition to the side
surround left and right channels.
“4” is used with 7.1-channel digital formats to indicate the presence
of two discrete side surround channels and two discrete back
The third number is used for the LFE channel:
“0” indicates no LFE channel.
“.1” indicates that an LFE channel is present.
The 6.1-channel signals – Dolby Digital EX and DTS-ES Matrix
and Discrete – each include a flag meant to signal the receiver to
decode the surround back channel, indicated as 3/2/.1 EX-ON for
Dolby Digital EX materials, and 3/3/.1 ES-ON for DTS-ES materials.
Dolby Digital 2.0 signals may include a Dolby Surround flag indicating
DS-ON or DS-OFF, depending on whether the 2-channel bitstream
contains only stereo information, or a downmix of a multichannel
program that can be decoded by the AVR’s Dolby Pro Logic
decoder. By default, these signals are played in Dolby Pro Logic IIx
When a PCM signal is received, the PCM message and the sampling
rate (32kHz, 44.1kHz, 48kHz or 96kHz) will appear.
When only two channels – left and right – are present, the analog
surround modes may be used to decode the signal into the remain-
ing channels. If you would prefer a different surround format than
the native signal’s digital encoding, press the OSD Button, and use
the Buttons to select “SURROUND SELECT”. Press the OK Button.
Use the Buttons to select one of the surround mode categories.
The Auto Select option uses the native signal’s digital encoding,
e.g., Dolby Digital, DTS, Dolby TrueHD or DTS-HD Master Audio.
For 2-channel materials, the AVR defaults to Logic 7 Movie mode.
If you prefer a different surround mode, select the surround mode
category: Virtual Surround, Stereo, Movie, Music or Video Game.
Press the OK Button to change the mode.
Each category is set to a default surround mode:
Harman Virtual Speaker
Logic 7 Movie
Logic 7 Music
Logic 7 Game
You may select a different mode. The choice of surround modes
depends on the number of speakers in your system.
Harman Virtual Speaker
2-channel stereo, 5-channel stereo or 7-channel stereo
Logic 7 Movie, DTS Neo: 6 Cinema, Dolby Pro Logic II
Movie, Dolby Pro Logic IIx Movie
Logic 7 Music, DTS Neo:6 Music, Dolby Pro Logic II
Music, Dolby Pro Logic IIx Music
Logic 7 Game, Dolby Pro Logic II Game, Dolby
Pro Logic IIx Game
Once you have programmed the surround mode for each type of
audio, select the line from the Surround Select menu to override
the AVR’s automatic surround mode selection. The AVR will use the
same surround mode the next time the source is selected.
Please refer to Table A9 in the appendix for more information on
which surround modes are available with different bitstreams.
Dolby Surround Settings
Some additional settings are available for Dolby modes. When
the Dolby Pro Logic II or IIx Music modes have been selected, the
Center Width, Dimension, Panorama and Night Mode settings will
become available. See Figure 25.
Figure 25 – Dolby Pro Logic II/IIx Music Mode Settings
Center Width: This setting affects how vocals sound through
the three front speakers. A higher number (up to 7) focuses the
vocal information tightly on the center channel. Lower numbers
broaden the vocal soundstage. Use the Buttons to adjust.
Dimension: This setting affects the depth of the surround
presentation, allowing you to “move” the sound toward the front
or rear of the room. The setting of “0” is a neutral default. Setting
“F-03” moves the sound toward the front of the room, while setting
“R-03” moves the sound toward the rear. Use the Buttons to
Panorama: With the Panorama mode turned On, some of the
sound from the front speakers is moved to the surround speakers,
creating an enveloping “wraparound” effect. Each press of the
OK Button toggles the setting on or off.
Night Mode: Night mode is available with some Dolby Digital
programs, if it has been encoded in the material. It compresses the
peak sound levels, maintaining the intelligibility of the dialogue and
quieter passages, while reducing the loudness of special effects
and louder passages, to avoid disturbing others. Three levels of
compression are available:
At this setting, there is no compression, as the Night mode
A mild compression is applied.
More compression is applied.
