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 48) are ineffective while
this function is activated.)
Touch
[
]
or
[
]
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 49).
•
“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 48).
•
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.
Setting item: X-OVER
1
Touch
[

of X-OVER.
A speaker list on the X-OVER screen is displayed.

of the speaker to be adjusted.
The screen changes to the X-OVER screen to be adjusted.
4
Adjust the crossover to your preference.
Selecting the Cut-Off Frequency
Touch
[
]
or
[
]
of FREQ., then select the cut-off frequency
(crossover point).
The adjustable bandwidth differs depending on the speaker
(channel).
Adjusting the Level
Touch
[
]
or
[
]
of LEVEL, then adjust the HPF or LPF level.
Adjusting the Slope
Touch
[
]
or
[
]
of SLOPE, then adjust the HPF or LPF
slope.
•
When the speaker is set to the “OFF” mode, the X-OVER for that
speaker cannot be set. Refer to “Setting the Speakers” (page 48).
•
Check the playback frequencies of the connected speakers before
adjusting.
•
In order to protect the speakers, there is no OFF setting for the
subwoofer low pass filter (the slope remains the same).
•
The HPF cannot be set SLOPE to OFF if Tweeter (TW) is selected
for FRONT1 . Or, only the subwoofer is adjustable if STEREO is
selected for the subwoofer.
Because of the particular conditions inside the vehicle, there can be
major differences in the distances between the various speakers and the
listening position. It is possible to calculate the optimum correction
values and eliminate the time error at the listening position yourself
using this function.
Setting item: T.CORR
1
Sit in the listening position (the driver’s seat, for
example) and measure the distance (in meters)
between your head and the various speakers.
2
Calculate the difference in distance between the
farthest speaker and the other speakers.
3
Divide the distances calculated for the different
speakers by the speed of sound (343 m/s
temperature 20°C).
This value is the time correction value for the various
speakers.
Concrete examples
Calculating the time correction value for the front left speaker on
the diagram below.
X-OVER Adjustment
L+R:
Sets the same adjustment values for the left and right
channels.
L/R:
Different adjustment values can be set for the left and
right channels.
Performing Time Correction Manually
(T.CORR)
L =
(distance of farthest speaker)
– (distance of other speakers)
Conditions:
Distance between farthest speaker and listening position:
2.25 m (88-3/4")
Distance between front left speaker and listening position:
0.5 m (20")
Calculation:
L = 2.25 m (88-3/4") – 0.5 m (20")= 1.75 m (68-3/4")
Compensation time = 1.75 ÷ 343 x 1000 = 5.1 (ms)
