You can independently change the balance, center
level, surround level, surround back level, and
subwoofer level to alter the balance of sound in
your surround system.
Changing the balance alters the level of both
the left and right main loudspeakers to shift
the position of the stereo image, keeping the
overall level of the sound the same. The other
adjustments change the level of the corresponding
speaker(s) without affecting the remaining
speakers in the surround system.

The surround mode determines how the sound
is divided between the loudspeakers in your
surround system. Each source is associated with
a default surround mode, which will be used
when you select that source, but you can choose
a different surround mode for the source if you
prefer.
For example, the standard surround mode for
the DVB source is PLIIX Movie, since most TV
broadcasts are Pro Logic encoded, but if you
are watching a music concert you may prefer to
choose the Stereo or Bypass surround modes, as
these give a more natural sound when listening
to music.
To change the surround mode
•
Press the
AUDIO
button on the remote
control to step between the available
surround modes.
The options available depend on the source you
are listening to.
