SELECTING A SURROUND MODE

Surround mode selection can be as simple or sophisticated as
your individual system and tastes. Feel free to experiment, and
you may find a few favorites for certain sources or program types.
More detailed information on surround modes may be found in
the Advanced Functions section.

To select a surround mode, press the Surround Modes Button
(front panel or remote). The Surround Modes menu will appear
(see Figure 26). Use the

Buttons until the desired surround

mode category appears: Auto Select, Virtual Surround, Stereo,
Movie, Music or Video Game. Press the OK Button to change
the audio type’s surround mode.

Figure 26 – Surround Modes Menu

Auto Select:

For digital programs, such as movies recorded

with a Dolby Digital soundtrack, the AVR will automatically use the
native surround format. For 2-channel analog and PCM programs,
the AVR uses Logic 7 Movie, Music or Game mode, depending on
the source.

Virtual Surround:

When only two main speakers are present

in the system, Dolby Virtual Surround may be used to create an
enhanced soundfield that virtualizes the missing speakers. Select
between Wide and Reference modes.

Stereo:

When 2-channel playback is desired, select the number

of speakers used for playback:

• 2 CH STEREO uses only two speakers. As described on page 40,

you may select Analog Bypass mode for a pure analog signal
when analog audio inputs are in use. Turn off the Tone Control
setting in the Audio Effects submenu, and the AVR does the rest.

• 5 CH STEREO plays the left-channel signal through the front

and surround left speakers, the right-channel signal through the
right speakers and a summed mono signal through the center
speaker.

• 7 CH STEREO follows the same scheme as 5 CH STEREO, but

adds the surround back speakers. This mode is only available
when the surround back speakers are present and have not
been reassigned to multizone operation. See page 47 for more
information.

Movie:

Use when a surround mode is desired for movie playback:

Logic 7 Movie, DTS Neo:6 Cinema or Dolby Pro Logic II (IIx when
seven main speakers are present).

Music:

Use when a surround mode is desired for music playback:

Logic 7 Music, DTS Neo:6 Music or Dolby Pro Logic II (IIx when
seven main speakers are present). The Dolby Pro Logic II/IIx Music
mode allows access to a submenu with some additional settings.
See the Advanced Functions section for more information.

Video Game:

Use to select a surround mode for game playback:

Logic 7 Game, or Dolby Pro Logic II (IIx when seven main speakers
are present) Game.

After you have made your selection, press the Back/Exit Button.

See the Advanced Functions section for more information on
surround modes.
