Pro Logic processing can be conducted on the music signals recorded
on two channels to achieve Dolby Pro Logic II surround sound. For
two-channel Dolby Digital and DTS signals, there is also a “REAR
FILL” function for outputting the signals of the front channel to the rear
channel.
Setting item: DOLBY PLII/REAR FILL
Touch
[

or
[

of DOLBY PLII/REAR FILL to select the
desired mode.
If PL II MUSIC is selected, the centre width can be adjusted with
following operations.
This function offers the optimum vocal position by adjusting the
centre channel position between the centre speaker and the L/R
speaker. (The adjustments established in “Adjusting the
acoustic image (Bi-Phantom)” (page 27) are ineffective while
this function is activated.)

of Center Width Cont. to adjust the level.
The level can be adjusted between 0 to +7. When the
level increases, the centre channel position moves from
the centre speaker position to both sides.
Touch
[OFF]
of Center Width Cont. to turn off the centre
width control.
• This adjustment is effective when the setting of the centre speaker is
SMALL or LARGE in the speaker setup settings (page 28).
• “REAR FILL” function:
Depending on the input signals, the sound may only be output from
the front speakers. In this case, the “REAR FILL” function can be
used to output signals from the rear speakers as well.
• Avoid stopping, pausing, switching the disc, cueing, fast-forwarding
or switching the audio channel of this unit while making this
adjustment. The setting is cancelled if the Decode mode is switched.
• This adjustment is ineffective when the speaker is set CENTER to
OFF in “Setting the Speakers” (page 27).
• This function only works with two-channel signals. This operation is
ineffective when 5.1-channel DTS or Dolby Digital signals are input.
• If the setting of REAR FILL is made when REAR MIX is ON, sound is
unchanged in the rear fill setting because REAR MIX is given priority
during 2 channel decoder other than linear PCM.
• For linear PCM signals, the voice is output from the rear speaker
regardless of the REAR FILL and REAR MIX setting.

adjusting.
• In order to protect the speakers, there is no OFF setting for the
subwoofer low pass filter (the slope remains the same).

for Front 1. If STEREO is selected for the subwoofer, this adjustment
is not available.
