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.

Figure 64 – Speaker/Channel Input Indicators

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.
