ChAnGinG the leVelS
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.
To change a level
•
Press the
_
button on the front panel, or the
BAL/ST
button on the remote control, until the display
shows the level you want to change.
The first step allows you to change the balance of the
main speakers:
0.0dB L=R 0.0dB
Subsequent steps allow you to change the levels of the
surround speakers:
CENTER 0.0dB
SUBWOOFER 0.0dB
SURROUND 0.0dB
SURR BACK 0.0dB

Use the
VOLUME
control on the front panel, or the

value.

After a short delay the display will revert to the normal
display.

value.
The AV Delay can be changed from 0ms to 250ms. After a
short delay the display will revert to the normal display.
ChooSinG the SUrroUnd Mode
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
display the current surround mode.
•
Press again to step between the available surround
modes.
The options available depend on the source you are
listening to.
