Using Dolby Surround
Adjusting the acoustic image
In most installations, the centre speaker must be
placed directly between the front passenger and
driver. Using this function, the centre channel
information is distributed to the left and right
speakers. This creates an acoustic image
simulating a centre speaker directly in front of
each listener. Adjusting the centre width in
DOLBY PL II MUSIC (see “Using the Pro Logic II
mode”, page 20), makes this function ineffective.
NOTE
Avoid stopping, pausing, switching the disc, cueing,
fast-forwarding or switching the audio channel of the
player while making this adjustment. The setting is
cancelled if the decode mode is switched.
1
Press the SETUP button.
The setup mode is set.
2
Turn the Rotary encoder to select the “5.1CH
SETUP” mode, then press the ENTER button.
3
Turn the Rotary encoder to select “BI-
PHANTOM”, then press the ENTER button.
4
Turn the Rotary encoder to select “BI-
PHANTOM ON” or “BI-PHANTOM OFF”, then
press the ENTER button.
When set to “ON”, the centre channel
information is distributed to the left and right
speakers. This creates an acoustic image
simulating a centre speaker directly in front of
each listener.
5
Turn the Rotary encoder to adjust the level,
then press the ENTER button.
The level can be adjusted within the range of –5
to +5. The higher the level, the more the position
of the centre speaker is shifted to the sides.
6
Once the settings are completed, press the
SETUP button repeatedly to quit the setup
mode.
NOTES
• This adjustment is ineffective if the centre speaker is
set to “OFF” or “Sub.W” in the speaker setup
settings.
• Once the settings are made, we recommend storing
them in the memory. See page 28 for instructions.
