Using the Dolby Pro Logic II
Dolby Pro Logic II creates five full-bandwidth
output channels from two-channel sources to
achieve high-purity matrix surround.
! If both the center and the rear speakers are
set to OFF, you cannot use this function.
! Dolby Pro Logic II supports up to 48 kHz
sampling rate stereo source and has no ef-
fect on other types of source.

Adjusting the Music mode
You can adjust the Music mode with the fol-
lowing three controls.
! Panorama (PANO) extends the front stereo
image to include the surround speakers for
an exciting
“wraparound” effect.
! Dimension (DIME) allows you to gradually
adjust the sound field either towards the
front or the rear.
! Center Width Control (CENTER) allows cen-
ter-channel sounds to be positioned be-
tween the center speaker and the left/right
speakers. It improves the left-center-right
stage presentation for both the driver and
the front passenger.

the center speaker. 7 places all center sound
equally in the left/right speakers.
Using the sound field control
The SFC function creates the sensation of a
live performance.
! The acoustics of different performance en-
vironments are not the same and depend
on the extent and contour of space through
which sound waves move and on how
sounds bounce off the stage, walls, floors
and ceilings. At a live performance you
hear music in three stages: direct sound,
early reflections, and late reflections, or re-
verberations. Those factors are programed
into the SFC circuitry to recreate the acous-
tics of various performance settings.
