ADVANCED FUNCTIONS
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
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 Movie mode.
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 Surround Modes
Button to display the Surround Modes menu (see Figure 30).
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:
• Virtual Surround: Harman Virtual Speaker
• Stereo: 7-channel stereo
• Movie: Logic 7 Movie
• Music: Logic 7 Music
• Video Game: Logic 7 Game
You may select a different mode. The choice of surround modes
depends on the number of speakers in your system.
• Virtual Surround: Harman Virtual Speaker
• 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
audio, 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 is selected.
Please refer to Table A13 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 30.
Figure 30 – 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 7/3 Buttons to adjust.
Dimension: This setting affects the depth of the surround pres-
entation, allowing you to “move” the sound toward the front or rear
of the room. The setting of “0” is a neutral default. Setting “F-3”
moves the sound toward the front of the room, while setting “R-3”
moves the sound toward the rear. Use the
7/3 Buttons to adjust.
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.
MANUAL SPEAKER SETUP
The AVR 2600 is flexible and may be configured for most speakers,
and to compensate for the acoustic characteristics of your room.
The EzSet/EQ process automatically detects the capabilities of each
speaker, and optimizes the AVR 2600’s performance. If you are
