The first number indicates the number of front channels in the signal:
“1” represents a monophonic recording, usually an older program that
has been digitally remastered or, more rarely, a modern program
for which the director has chosen a special effect.
“2” indicates the presence of the left and right channels, but no
center channel.
“3” indicates that all three front channels (left, right and center)
are present.
The second number indicates whether any surround channels are present:
“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 surround channels.
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 con-
tains 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 Movie mode.
When a PCM signal is received, the PCM message and the sampling
rate (32kHz, 44.1kHz, 48kHz or 96kHz) will appear.
The Speaker/Channel Input Indicators indicate the number of channels
discretely encoded in the signal by displaying a letter inside that channel’s
speaker box. A line connects the SBL and SBR boxes when a 6.1-
channel signal is detected, indicating that the same signal is playing
through both speakers.The letters flash when no signal is present,
such as when a disc is paused. See Figure 64.

When only two channels – left and right – are present, the analog surround
modes may be used to decode the signal into the remaining channels.
If you would prefer a different surround format than the native signal’s
digital encoding, press the Surround Modes Button to display the
Surround Modes menu (see Figure 63).
The Auto Select option uses the native signal’s digital encoding, e.g.,
Dolby Digital or DTS. For 2-channel materials, the AVR defaults to
Logic 7 Movie mode. If you prefer a different surround mode, select the
processing type: Virtual Surround, Stereo, Movie, Music or Video Game.
Press the OK Button to change the mode.
Each processing type is set to a default surround mode:
• Virtual Surround: Dolby Virtual Speaker Reference
• Stereo: 7-channel stereo
• Movie: Logic 7 Movie
• Music: Logic 7 Music
• Video Game: Logic 7 Game
The choice of surround modes depends on the number of speakers in
your system.
• Virtual Surround: Dolby Virtual Speaker Reference or Wide
• Stereo: 2-channel stereo, 5-channel stereo or 7-channel stereo
• Movie: Logic 7 Movie, DTS Neo 6:Cinema, Dolby Pro Logic II Movie,
Dolby Pro Logic IIx Movie
• Music: Logic 7 Music, DTS Neo 6:Music, Dolby Pro Logic II Music,
Dolby Pro Logic IIx Music
• Video Game: Logic 7 Game, Dolby Pro Logic II Game, Dolby
Pro Logic IIx Game
Once you have programmed the surround mode for each type of pro-
cessing, select the line from the Surround Modes menu to override the
AVR’s automatic surround mode selection. The AVR will use the same
surround mode the next time the source input is selected.
Please refer to Table A12 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, choose the Edit
submenu to adjust the Center Width, Dimension and Panorama settings.
See Figure 65.
