Adjusting the Acoustic Image (BI-
PHANTOM)
To install a center speaker, it must be located in the dash, an equal
distance between the Left and Right speakers. In most cases, this is very
difficult to achieve. Using Bi-PHANTOM, a virtual center speaker is
created by sending the center channel information to both the Left and
Right speakers. Adjusting the center width in Dolby Pro Logic II
“Music” (see “Using Dolby Pro Logic II (Dolby PLII)” on page 53),
makes this function ineffective. This is used in a system where there is
no sub-woofer and the rear speakers can produce lower frequency
sounds than the front speakers. (Initial setting: “OFF”, “±0 dB”)
1
Press [FUNC.].
2
Rotate the [Rotary encoder] to select “Multi Ch.
Setup,” and then press the [Rotary encoder].
3
Rotate the [Rotary encoder] to select “BI-
PHANTOM,” and then press the [Rotary encoder].
4
Rotate the [Rotary encoder] to select “ON,” and then
press the [Rotary encoder].
Turning this feature on creates the acoustic image in which
the center speaker is virtually located exactly in front of the
listener by splitting the sound of the center speaker into
both sides.
5
Adjust the level by rotating the [Rotary encoder].
LEVEL: -5 to +5 dB (in 1 dB steps)
The level can be adjusted between -5 and +5. When the
level becomes greater, the acoustic image moves from the
center speaker location toward both sides.
6
When the setting is complete, press and hold [ ]
for at least 2 seconds.
• If [ ] is pressed during setting, the unit returns to the previous
item.
• Do not perform operations such as Stop/Pause/Disc Exchange/Cue/
Fast Forward/Audio Switching on the player during this setup
adjustment. When the decode state switches, the settings will be
cancelled.
• When the Center speaker is off in “Setting the Speaker System
(System Select)” (page 37)/“Setting the Speakers (Speaker Setup)”
(page 38), this item cannot be set.
• Effective only for Dolby Pro Logic II, EUPHONY and DTS (with
Center signal).
• After the setting, it is recommended to store the setting contents on
the unit. For details, refer to “Storing the Preset Values (Preset
Store)” (page 36).
Mixing the Low Range Audio for the Rear
(Rear Mix)
This function mixes the front channel audio signals to the audio signals
output from the rear speakers, improving the sound in the vehicle’s rear
seat. This is used in a system where there is no subwoofer and the rear
speakers can produce lower frequency sounds than the front speakers.
(Initial setting: “OFF”, “±0 dB”)
1
Press [FUNC.].
2
Rotate the [Rotary encoder] to select “Multi Ch.
Setup,” and then press the [Rotary encoder].
3
Rotate the [Rotary encoder] to select “Rear Mix,” and
then press the [Rotary encoder].
4
Rotate the [Rotary encoder] to select “ON,” and then
press the [Rotary encoder].
Turning this feature ON mixes the audio signals output from
the rear speakers with the front audio signals.
5
Adjust the level by rotating the [Rotary encoder].
LEVEL: -6/-3/0/+3/+6 dB
The level can be adjusted in 5 steps. The higher the level,
the more the low range audio is output from the rear
speakers. (Depending on the software such as DVD, the
effect may vary.)
6
When the setting is complete, press and hold [ ]
for at least 2 seconds.
• If [ ] is pressed during setting, the unit returns to the previous
item.
• 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.
• When the Rear speaker is off in “Setting the Speaker System (System
Select)” (page 37)/“Setting the Speakers (Speaker Setup)”
(page 38), this item cannot be set.
• Effective only for Dolby Pro Logic II, EUPHONY and DTS (with
Rear signal).
• After the setting, it is recommended to store the setting contents on
the unit. For details, refer to “Storing the Preset Values (Preset
Store)” (page 36).
