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
